Cataract surgery in Switzerland: regaining clear vision

A cataract is the gradual clouding of the crystalline lens, the natural lens inside the eye. It blurs vision, dulls colours and makes glare troublesome, particularly when driving at night. Its operation, which replaces the clouded lens with a clear implant, is one of the most commonly performed and most effective procedures in medicine. In Switzerland, it is covered by basic insurance when the cataract impairs vision. This page explains when to operate, how the procedure works, how to choose your implant, what the options cost, what the risks are and where to have surgery in each of the 26 cantons.

Cataract surgery is performed under local anaesthesia, often with drops alone, as day surgery, in fifteen to thirty minutes per eye. The lens is broken up and aspirated through an incision of a few millimetres, then replaced with an implant. Vision improves within a few days. The two eyes are operated on separately, a few days or weeks apart. The procedure and standard implant are covered by basic insurance; a premium implant, which reduces dependence on glasses, involves a supplement at your expense.

Causes

The main cause is age: most people develop a cataract after sixty-five. Diabetes, certain medicines such as long-term corticosteroids, smoking, ultraviolet exposure, high myopia, injury or previous eye surgery can accelerate it.

Symptoms

Blurred or hazy vision, glare from headlights or the sun, dull or yellowed colours, needing more light to read, frequent changes of glasses, sometimes double vision in one eye.

Progression

Cataract progresses slowly, over months or years. It is not treated with drops or glasses; only surgery corrects it.

The crystalline lens is a flexible, transparent lens about the size of a lentil, located just behind the iris. It is enclosed in a thin capsule, suspended by hundreds of very fine fibres, the zonules, which connect it to the muscle responsible for changing its shape. In children and young adults, this muscle can make the lens more curved to see close up: this is accommodation.

The lens grows throughout life by adding layers of fibres, rather like an onion. Over the years, it becomes harder, which explains presbyopia after forty, then less transparent, which leads to cataract. These two phenomena are two stages of the same ageing process.

During the operation, the surgeon keeps the capsule, which serves as a natural support for the implant. The zonules, sometimes fragile in very elderly people or after certain diseases, hold everything in place.

Cataract is one of the most common reasons for surgery in Switzerland, as in all countries with an ageing population. The vast majority of people over seventy-five have some degree of lens clouding, even if not all of them yet experience difficulty. Cataract surgery is among the most frequently performed surgical procedures.

This frequency has a positive consequence: surgeons have very extensive experience of this procedure, techniques are standardised and results are excellent. There is no reason to fear this operation, although any surgery deserves good preparation.

The ophthalmologist distinguishes several forms of cataract according to the area of the lens that becomes cloudy. Nuclear cataract affects the centre; it gradually yellows vision and can make the eye more short-sighted. Cortical cataract forms spokes at the periphery; it mainly causes glare against the light. Posterior subcapsular cataract, located just in front of the back capsule, quickly impairs reading and vision in bright light; it is common with cortisone and diabetes.

These forms often combine. They explain why two people with cataracts of the same severity do not describe the same symptoms. All are treated by the same operation.

• Difficulty reading road signs or subtitles.
• Glare from headlights at night or from a low sun.
• Needing a stronger lamp to read or sew.
• Faces less sharp, difficulty recognising people at a distance.
• Dull colours, difficulty distinguishing navy blue from black.
• Frequent changes of glasses without real improvement.
• Difficulty with golf, tennis or hiking in bright weather.

These signs develop so gradually that many patients only realise the extent of their difficulty after the first eye has been operated on, by comparing the two. Someone close to you sometimes notices before you do that you get closer to the television or hesitate on the stairs.

No measure guarantees that cataract will be avoided, but limiting modifiable factors can delay its onset. A diet rich in fruit and vegetables and not smoking are beneficial for eye health in general.

Loss of vision in an older person is not always due to a cataract. Macular degeneration, glaucoma, diabetic retinopathy, a retinal vessel occlusion or significant dry eye can cause similar symptoms, and several causes often coexist. That is why a complete examination of the back of the eye is essential before deciding on an operation.

If another disease is present, the operation may still be useful, but the gain in vision will be limited by that disease. The ophthalmologist explains what you can reasonably expect, to avoid disappointment.

• "A cataract is a film over the eye": false — it is the lens, inside the eye, that becomes cloudy.
• "The operation is done by laser": the operation is mainly performed with ultrasound; laser is only used for certain steps in some centres, or for posterior capsule opacification.
• "You have to wait until it is ripe": false — surgery is performed when the difficulty appears.
• "Cataract can come back": false — only the capsule can become cloudy, and this is treated by laser.
• "You can't have surgery after ninety": false — age is not a limit.
• "Drops can dissolve a cataract": false — no medical treatment makes it disappear.

Rarely, a child is born with a cataract or develops one in the first few years. It may be discovered as a white reflex in the pupil, visible in a photo or during the newborn examination, a squint or a child who seems not to see well. It must be treated quickly, as the child's brain needs sharp images to develop vision; without treatment, a permanent lazy eye can develop.

The operation is performed under general anaesthesia in paediatric ophthalmology centres, often university centres. It is followed by prolonged rehabilitation, with glasses, contact lenses and patching of the good eye, and follow-up into adulthood. Any white reflex in a child's pupil justifies a consultation without delay.

For centuries, cataract was treated by couching, which involved pushing the lens to the back of the eye, with poor results. In the eighteenth century, extraction of the lens through a large incision developed, but patients then had to wear very thick glasses. The invention of the intraocular implant in the mid-twentieth century changed everything by replacing the lens with an artificial one.

Phacoemulsification, developed from the 1960s and widely adopted since, made it possible to reduce incisions to a few millimetres, then foldable implants made it possible to insert them through these small incisions. Today, the operation is quick, performed as day surgery and very safe, with increasingly sophisticated implants.

A violent blow to the eye, a penetrating wound, an electric shock or certain radiation can cause a cataract, sometimes immediately, sometimes months or years later. It often affects one eye only and frequently concerns young people. The injury may have damaged other structures, such as the zonules, iris or retina, which makes the operation more complex and justifies treatment in an experienced centre.

When the cataract results from an accident, coverage may fall under accident insurance. Keep the documents relating to the accident and tell the ophthalmologist about it.

Besides cortisone, other treatments can encourage cataract or complicate its operation, such as certain prostate medicines, already mentioned, or some treatments used in psychiatry or dermatology. Conversely, no medicine has been shown to prevent or reverse cataract. At the assessment, bring the complete list of your treatments, including eye drops and food supplements.

It is no longer necessary to wait for a cataract to be "ripe". Surgery is performed when it interferes with daily life: reading, driving, work or leisure activities, safety, particularly the risk of falling. The decision is made with the ophthalmologist, according to the difficulty experienced, the measured visual acuity and the general condition of the eye. For driving, insufficient vision may no longer meet the legal requirements; the operation often restores them.

There is no universal vision threshold at which surgery should be performed. The decision is based on the difficulty experienced: problems driving, reading, recognising faces, enjoying leisure activities, moving around safely. An active person who drives a lot at night may be troubled by a mild cataract, while another, less exposed, will cope with a more advanced cataract.

The ophthalmologist measures vision under standard conditions, but also sometimes glare sensitivity, which better reflects the real difficulty. They ask you how your vision affects your daily life. Your opinion counts as much as the figures: you are the one living with this vision.

There is generally no urgency. The operation can be scheduled at a time that suits you, while avoiding waiting too long once the difficulty has set in.

To drive, the regulations set minimum vision requirements, checked during periodic medical examinations of older drivers. A cataract can bring acuity below these thresholds, or cause dangerous glare at night, without the driver being fully aware of it. The ophthalmologist may advise you to stop driving until the operation.

After the operation, vision often meets the requirements again, sometimes without glasses. If your licence states that you must wear a correction and you no longer need it, ask your canton's road traffic office about the procedure for having it changed.

In older people, blurred vision and poor perception of contrast and depth increase the risk of falling, particularly on stairs, pavements or in dim light. Falls can have serious consequences, such as fractures. Several studies show that cataract surgery reduces this risk and improves independence.

The operation can also improve quality of life more broadly: resuming reading, social activities and leisure, better orientation. In people with memory problems, better vision often helps maintain orientation. These benefits are important reasons not to delay the procedure once the difficulty is there.

Declining vision can lead people to go out less, give up reading, board games or driving, and encourage withdrawal, or even low morale, in older people. Cataract surgery, by restoring clear vision, often allows these activities to be resumed and social life to be regained. This is an important benefit to consider in the decision, beyond visual acuity figures.

After the first eye has been operated on, the difference between the operated eye, which sees clearly, and the other, still hazy, can be troublesome, especially if the prescriptions of the two eyes are very different. This situation, called anisometropia, can cause double vision, dizziness or difficulty wearing glasses. For this reason, the second eye is often operated on a few days to a few weeks after the first.

If the second eye has a mild cataract with no real difficulty, you can also wait. A contact lens on the non-operated eye can sometimes help during the interim period. The decision is made with the surgeon according to your symptoms.

Some centres offer surgery on both eyes in the same session, with strict precautions: each eye is treated as a separate procedure, with separate equipment and products. This approach reduces the number of trips and anaesthetics and the period of imbalance between the two eyes, which can be useful for elderly patients or those living far away.

It does, however, rule out adjusting the calculation for the second eye according to the result of the first, and it is not offered in complex situations, with an associated eye disease or a particular risk of infection. Most patients are still operated on in two stages.

After only one eye has been operated on, it is normal for the two eyes to see differently: one clear and bright, the other hazy and yellowish. If the prescriptions of the two eyes are very different, the brain may have difficulty merging the images, which gives a feeling of imbalance or double vision. This situation is temporary and resolves with the operation on the second eye or, in the meantime, with a suitable contact lens or glasses.

Most patients have both eyes operated on a few days or weeks apart. It is useful to plan both dates, the people accompanying you, the check-ups and any home help from the outset. Allow about a month in total between the first operation and the prescription of final glasses. If you have trips or important family events, organise the timetable accordingly.

The implant power is calculated from two main measurements: the length of the eye, measured by an optical device in a few seconds, and the curvature of the cornea. Mathematical formulas, refined by decades of experience, predict the power that will give the desired vision. Modern devices also measure the depth of the anterior chamber and the thickness of the lens, which improves precision.

Despite this precision, a small error remains possible, particularly in very highly short-sighted or long-sighted people, and after LASIK. It is generally corrected with light glasses. The surgeon tells you in advance if your eye presents a situation where the calculation is more delicate.

With a monofocal implant, you have to choose the distance at which you want to see clearly without glasses. Most patients choose distance vision, for driving and getting around, and wear glasses for reading. Others, often former short-sighted people used to reading without glasses, prefer a slightly short-sighted setting to read without correction and wear glasses for driving.

It is also possible to set the two eyes differently, with monovision. This choice is very personal: think about what you do most often without glasses and what bothers you most. The surgeon helps you find the setting that suits you.

Depending on your situation, other tests may be carried out before the operation: macular tomography, which detects a disease of the central retina that may limit the result; corneal topography, useful with astigmatism or for a premium implant; a count of corneal cells if the cornea is fragile; an ultrasound scan when the cataract is too dense to see the back of the eye.

These tests are painless and quick. Those needed for a standard operation are covered by insurance; some tests linked exclusively to premium implants may be billed separately.

The inner surface of the cornea is lined with cells that keep it transparent by pumping out water. In some people, particularly with Fuchs' dystrophy, these cells are fewer. Cataract surgery can weaken them further and cause lasting swelling of the cornea. The surgeon counts them before the procedure and adapts the technique to protect them.

In advanced cases, cataract surgery can be combined with or followed by a transplant of the inner layer of the cornea, which restores its transparency. This situation is assessed in specialist centres.

• Rose, 74, dazzled at night at the wheel: monofocal implants set for distance, reading glasses; she resumes night driving.
• Henri, 68, formerly short-sighted and a keen reader: slightly short-sighted setting in both eyes; he reads without glasses and wears glasses for driving.
• Claire, 63, active, marked astigmatism: toric implants, clear distance vision without glasses.
• Paul, 66, architect, works at a screen: extended depth-of-focus implants, glasses only for small print.
• Marguerite, 88, lives alone: both eyes operated on three weeks apart, home nurse for the drops.
• Jean, 71, treated glaucoma: cataract operated on with a glaucoma device at the same time, fewer drops afterwards.

When the wait before the operation is several weeks or months, a few measures improve daily life: stronger, directed lighting for reading, magnifiers, tinted sunglasses against glare, avoiding driving at night or in the rain, making the home safe against falls, with lighting on the stairs and removal of slippery rugs. Updating glasses can sometimes help at first.

If the difficulty worsens quickly, or if your safety is at stake, mention it: the wait can sometimes be shortened, or another facility may offer an earlier date.

Some people postpone the operation out of apprehension or because they gradually get used to poorer vision. Yet a very advanced cataract makes the operation more delicate, with more ultrasound energy needed, a slightly higher risk of complications and slower recovery. A very swollen cataract can also, rarely, cause glaucoma or inflammation. Surgery should not be performed too early, but there is no point waiting long once the difficulty has set in.

• Bring your current glasses and old prescriptions.
• Note your specific difficulties: driving, reading, glare, screens.
• List your medicines, particularly anticoagulants and prostate medicines.
• Mention your conditions: diabetes, glaucoma, retinal diseases.
• Come accompanied if pupil dilation is planned.
• Prepare your questions about implants and costs.

The assessment

The ophthalmologist measures the length of the eye and the curvature of the cornea, calculates the implant power, examines the retina and discusses with you the type of implant and your vision needs.

Anaesthesia

Usually, anaesthetic drops are enough, sometimes supplemented by an injection or light sedation. You remain awake, without pain.

Phacoemulsification

Through an incision of two to three millimetres, the surgeon opens the lens capsule, breaks the lens up with ultrasound and aspirates it.

Placing the implant

A folded implant is inserted into the capsule left in place, where it unfolds. The incision generally closes on its own.

Going home

After a short period of monitoring, you go home accompanied, with a protective shield and eye drops.

What about laser?

In some centres, a femtosecond laser performs some of the steps, such as opening the capsule or fragmenting the lens. This assistance can be useful in certain situations, but studies have not shown general superiority over the standard technique. It generally involves a supplement at the patient's expense.

• Mention all your medicines, including prostate medicines, past or present.
• Do not change your anticoagulants without instructions.
• Control diabetes or blood pressure as well as possible.
• Treat any eyelid infection or conjunctivitis before the operation.
• Arrange for someone to accompany you and the journey.
• Prepare the home: drops within reach, lighting, simple meals.

Many cataract patients take an anticoagulant or antiplatelet drug, for a heart rhythm disorder, a valve prosthesis or after a heart attack. As the operation is performed through small incisions without significant bleeding, these treatments are usually continued, particularly under anaesthetic drops. Stopping them without reason would expose you to a cardiovascular risk far more serious than the risk of bleeding in the eye.

If an injection around the eye is planned, or in a particular situation, the anaesthetist may ask for an adjustment, always in liaison with the doctor who prescribed the treatment. Do not change anything yourself.

In people with diabetes, it is important that blood sugar is well controlled before the operation and that the retina has been examined. Retinopathy or macular oedema must be treated beforehand, as the operation can temporarily worsen them. On the day of the procedure, fasting instructions and diabetes medication are adapted by the team. After the operation, the macula is monitored particularly closely.

Most heart and respiratory diseases do not contraindicate cataract surgery, which is short and under local anaesthesia. You must be able to lie flat for about twenty minutes; people who have difficulty breathing lying down, cough a lot or have back pain should mention it, and the team can adapt the positioning. Very high blood pressure on the day of the operation may lead to it being postponed.

• Assessment appointment done and implant chosen.
• Fasting and medication instructions understood.
• Someone arranged to accompany you there and back.
• Drops bought if prescribed in advance.
• Sunglasses and eye shield ready.
• Centre's number noted, including outside opening hours.
• Home help arranged if necessary.

• Can I keep my hearing aid in? Yes, generally; it even makes communication with the team easier.
• Can I keep my dentures in? Often yes for local anaesthesia; follow the instructions.
• Can I wear my jewellery? Better to leave it at home.
• Can I wash my hair? Yes, head tilted back, without water in the eye, in the first week.
• Can I sleep on my front? Better to avoid it in the first week.

Patients often mention the same reassuring elements: knowing exactly what will happen on the day, being accompanied, having a contact number, understanding the choice of implant, and hearing the team announce each step during the procedure. Many say afterwards that the operation was much simpler and quicker than they had imagined, and regret having put it off.

In the morning, take your usual medicines unless told otherwise, wash your face without make-up or cream, and dress comfortably. On arrival, the team checks your identity, the eye to be operated on, which is marked, and the planned implant model. Drops are applied to dilate the pupil, which takes about thirty minutes, then anaesthetic drops.

In the operating theatre, you lie down with your head stabilised. The skin around the eye is disinfected and a sterile drape covers the face, leaving the eye free, with air supplied under the drape. A speculum holds the eyelids open. You see a bright light and coloured shapes; you hear the noise of the device. The surgeon talks to you and warns you of each step.

After the procedure, a shield or dressing is placed over the eye. You stay in the recovery room for a while, a snack is often offered, then you go home accompanied, with the drops and written instructions.

Light intravenous sedation can be added to help you relax. The choice is made with the anaesthetist, according to your health, anxiety and the expected complexity. In most cases, anaesthesia with drops is enough and allows a quick return home.

• Two to three small incisions at the edge of the cornea, of one to three millimetres.
• Injection of a protective gel that maintains the space and protects the cornea.
• Circular opening of the front lens capsule.
• Separation of the lens from its capsule by injecting fluid.
• Fragmentation and aspiration of the nucleus by ultrasound.
• Aspiration of the softer peripheral layers.
• Injection of the folded implant, which unfolds in the capsule.
• Removal of the protective gel and checking that the incisions are watertight.

Some situations make the operation more delicate: a pupil that dilates poorly, common with certain prostate medicines or diabetes; a very dense cataract; fragile zonules, for example with pseudoexfoliation; a very short or very long eye; previous retinal surgery or injury. The surgeon identifies them during the assessment and plans suitable instruments and techniques.

These situations slightly increase the risk of complications, but the result remains good in the vast majority of cases. They sometimes justify entrusting the procedure to a particularly experienced surgeon or centre, notably in hospital.

Pseudoexfoliation is a common condition in older people, particularly in certain populations, in which a fine whitish deposit forms on the lens and in the eye. It weakens the zonules that hold the lens, causes poor pupil dilation and encourages glaucoma. It makes cataract surgery slightly more delicate.

The surgeon detects it during the assessment and takes particular precautions: devices to dilate the pupil, a capsular tension ring if necessary. Years after the operation, the capsule and implant can more rarely shift together; a sudden drop in vision requires medical attention.

A vitrectomy, performed for retinal detachment, a macular hole or a membrane, often accelerates the development of a cataract in the following months or years. Cataract surgery remains possible, but requires experience, as an eye without vitreous behaves differently during the procedure. Implant calculation may also be more delicate. It is often performed in centres used to these situations.

People who have had repeated eye inflammation, or uveitis, more often develop cataract, also encouraged by cortisone-based treatments. The operation is possible, but the eye must have been calm for several months, and intensified anti-inflammatory treatment is often prescribed before and after the procedure to prevent a flare-up. Follow-up is carried out in liaison with the specialist managing the inflammation.

In people with memory problems or dementia, cataract worsens disorientation, the risk of falling and isolation. The operation can improve independence and quality of life, provided the organisation is adapted: suitable anaesthesia, sometimes general if the person cannot stay still, constant support, help with drops and supervision to prevent them rubbing the eye. The decision is made with the family, the GP and the ophthalmologist.

In people with macular degeneration, cataract adds haze to central vision that is already impaired. The operation can improve clarity, colours and brightness, and make it easier to monitor the macular disease by making the back of the eye more visible. It does not, however, restore fine vision lost because of the macula.

Multifocal implants are not advised in this situation. Patients treated with injections for a wet form continue their treatment; the operation is scheduled in coordination with the injection schedule. It is important to have realistic expectations, discussed with the ophthalmologist.

When a person has only one seeing eye left, because of another disease or an accident, cataract surgery on that eye understandably causes concern. It generally remains indicated when the difficulty is significant, as it can restore precious independence. Precautions are increased: an experienced surgeon, careful preparation, home help during recovery and close monitoring. The decision is made by carefully weighing benefits and risks with the ophthalmologist.

Certain medicines used to make urination easier in men, and sometimes prescribed to women, make the iris floppy during the operation: it billows, constricts and can hinder the surgeon. This can occur even if the treatment was stopped long ago. It is essential to mention these medicines, current or past, during the assessment.

Once informed, the surgeon uses drops, products or small devices to stabilise the iris, and the operation proceeds normally. It is generally not useful to stop the treatment before the operation.

In some centres, a femtosecond laser performs the corneal incisions, the circular opening of the capsule and pre-cutting of the lens before the manual phase. The patient first goes under the laser, then under the operating microscope for the rest of the procedure. This technique offers great reproducibility of certain steps, and can be useful in particular situations.

For most patients, studies have not shown a clear difference in visual result or safety compared with a well-mastered manual technique. The laser involves an extra cost, generally at the patient's expense, and slightly lengthens the total time in theatre.

In patients with glaucoma, cataract surgery can be an opportunity for an additional procedure to lower eye pressure, using small devices implanted in the fluid drainage pathways, performed in the same session. This combination can reduce the number of drops needed. In angle-closure glaucoma, simply replacing the lens, which frees up space in the eye, is often very beneficial.

Glaucoma follow-up continues after the operation, with regular pressure measurements and visual field tests. Multifocal implants are generally not advised with advanced glaucoma.

Because it is short, frequent and performed as day surgery, cataract surgery is sometimes trivialised. It nevertheless remains real surgery inside the eye, requiring a serious assessment, an experienced team, strict hygiene conditions and rigorous follow-up. The procedure's very high level of safety depends on these precautions, and on the patient's participation: using the drops properly, protecting the eye and reporting any unusual symptom promptly.

This rigour also explains why the two eyes are often operated on separately, why you are asked not to swim in the first few weeks, and why the first check-up is important even if you already see well.

Cataract surgery is performed by ophthalmologists trained in microsurgery, many of whom perform hundreds of procedures each year. For a simple cataract, the surgeon's general experience is more than enough. For a complex situation, such as fragile zonules, a very dense cataract, previous retinal surgery or a fragile cornea, it may be useful to choose a surgeon or centre that regularly handles these cases. Do not hesitate to ask.

Infection prevention begins before the operation, by treating any infection of the eyelids or tear ducts. On the day, the skin and eye surface are disinfected with an antiseptic, the equipment is sterile and often single-use, and many centres inject an antibiotic into the eye at the end of the procedure. After the operation, drops, the shield, no rubbing and no swimming complete these measures. Together, they make serious infection very rare.

Premium implants reduce dependence on glasses, but can cause halos or a loss of contrast at night, and do not suit every eye, for example with retinal disease or advanced glaucoma. The choice is made with the ophthalmologist according to your lifestyle.

This table gives general trends. The choice must take into account the condition of your eyes, your activities and your tolerance of trade-offs. Our page on intraocular lenses details each family of implants.

• At which distance do I most need to see without glasses?
• Do I often drive at night?
• Do I read a lot, for long periods, or small print?
• Do I work at a computer?
• Does the idea of wearing reading glasses bother me?
• Am I prepared to accept halos around lights?
• What budget am I prepared to spend on a premium implant?

Short-sighted people are often used to reading without glasses, by taking them off. If the implant is set for perfect distance vision, they will lose this ability and need reading glasses, which is sometimes a surprise. Some prefer to keep slight myopia to continue reading without glasses, and wear glasses for driving.

Highly short-sighted people should also know that their retina is more fragile and that the risk of retinal detachment after the operation is slightly higher. They need to know the warning signs and seek help without delay in the event of flashes or a curtain.

Highly short-sighted people often develop cataract earlier than average, sometimes in their fifties. Their eye, which is longer, has a thinner, more fragile peripheral retina, with a slightly higher risk of detachment after the operation. The assessment includes a careful examination of the retina, and a fragile area can be treated preventively by laser before the procedure.

After the operation, highly short-sighted people often discover clear distance vision without their thick glasses, which changes their daily life. They must, however, remain vigilant: flashes, a shower of floaters or a curtain justify a consultation the same day, even years later.

Long-sighted people have often worn glasses for distance and near, getting stronger with age. Cataract surgery corrects their hyperopia, and many discover clear distance vision without glasses for the first time in years. As their eye is shorter, it also sometimes has a narrow angle that carries a risk of angle-closure glaucoma; replacing the lens frees up space and reduces this risk.

Implant calculation is slightly more delicate in very short eyes, but current formulas give good results.

Astigmatism usually comes from the cornea, which is not perfectly round. It is not corrected by a standard implant and persists after the operation. Slight astigmatism is often well tolerated or corrected by glasses. For more significant astigmatism, a toric implant, positioned along the measured axis, clearly improves vision without glasses.

The position of the toric implant is marked using reference marks or a guidance system, as a few degrees of rotation reduce its effectiveness. If the implant rotates in the following days, it can be repositioned. The extra cost of the toric implant is generally at the patient's expense.

The implants used in Switzerland are certified medical devices, made of biocompatible materials, usually soft acrylic. Each implant is identified by its model, power and batch number, recorded in your file and often on a card given to you after the operation. This traceability allows the implant to be identified if needed.

Keep this card with your important documents: it will be useful if you consult another ophthalmologist, if posterior capsule opacification needs to be treated, or for any future eye procedure.

In the first few weeks after a multifocal implant is fitted, many patients notice halos or rings around lights at night, and near vision that requires sufficient lighting. The brain gradually learns to interpret these new images: this is called neuroadaptation. It takes a few weeks to a few months.

Most patients adapt and appreciate doing without glasses day to day. A minority remain bothered; the ophthalmologist then looks for a treatable cause, such as dryness, posterior capsule opacification or a small refractive error. Implant exchange remains exceptional.

Research aims to better restore near vision without the drawbacks of multifocal implants: implants whose power can be adjusted by light after the operation, accommodating implants that try to reproduce the flexibility of the natural lens, and new optics that reduce halos. Some of these technologies are already available in a few centres, others are still being studied. Your surgeon can tell you whether one of them is relevant in your case.

Intermediate vision, at the distance of a computer screen or dashboard, plays a growing role in daily life, including after retirement: tablets, computers, cooking, music. With a monofocal implant set for distance, screens may require suitable glasses. Extended depth-of-focus implants or enhanced monofocal implants offer better intermediate vision.

If you spend a lot of time at a screen, tell the surgeon: it is an important criterion in choosing the implant and target vision.

Beyond sharpness, cataract reduces contrast perception: seeing a step in dim light, a face against the light, a sign in the rain. After the operation, contrast sensitivity improves markedly with a monofocal implant. With a multifocal implant, it may be slightly reduced, which matters for certain activities, such as night driving or certain occupations. This trade-off is part of the discussion about choosing the implant.

People whose activity depends on fine colour perception, such as painters, photographers or graphic designers, often notice a major change after the operation: the disappearance of the lens's yellow filter makes blues and violets more intense. Some famous artists even changed their palette after their operation. It sometimes takes a few weeks to recalibrate your perception, especially between the operations on the two eyes.

Musicians, dressmakers, watchmakers or DIY enthusiasts need precise vision at particular distances. It is useful to measure the distance at which you read a score, work at your bench or sew, and to tell the surgeon. The implant or glasses setting can be optimised for this distance, for example with glasses dedicated to the activity.

Monovision involves setting the dominant eye for distance vision and the other eye for intermediate or near vision. With monofocal implants, it reduces the need for glasses without the halos of multifocal implants. A moderate difference between the two eyes, called partial monovision, is often better tolerated and allows most texts to be read and a screen to be seen without glasses.

People who have already worn contact lenses in monovision know whether they tolerate it. For others, a prior trial is not always possible with an advanced cataract. Monovision slightly reduces depth perception and can hinder certain activities, such as ball sports or night driving. It is discussed with the surgeon according to your priorities.

Between the conventional monofocal implant and extended depth-of-focus implants, a category of so-called enhanced monofocal implants offers a slight extension of vision towards intermediate distance, for example to see a dashboard or a screen at arm's length, while keeping the optical quality and absence of halos of a monofocal. Depending on the model, they may be covered or involve a supplement; ask the centre.

The supplement for a premium implant is a one-off expense, for an implant that will last a lifetime. For some patients, a lasting reduction in dependence on glasses justifies this investment; for others, good-quality reading glasses remain the simplest and most economical solution. There is no right or wrong choice: the key is to decide with knowledge of the benefits and trade-offs.

Avoid rubbing the eye, bending head-down for long periods, lifting heavy loads and swimming pools in the first few weeks. Reading, television and screens are possible quickly. Driving resumes after the check-up that confirms sufficient vision.

On the evening of the operation, rest and keep the shield on. A gritty sensation, watering and still blurred vision are normal. The next day, remove the shield, gently clean the eyelids with a damp sterile compress, from the inner corner outwards, and use the drops according to the prescription. The first check-up checks eye pressure, the absence of significant inflammation and the position of the implant.

During the first week, you can walk, read, watch television, cook and shower, avoiding soapy water running into the eye. Avoid rubbing the eye, heavy exertion, dust and swimming. Wear the shield at night and sunglasses outdoors if the light bothers you.

• Check your vision every day by covering the other eye.
• Note whether the pain decreases from one day to the next, as expected.
• Watch for redness that increases instead of decreasing.
• Look out for flashes, many floaters or a curtain.
• If in doubt, call the centre rather than waiting for the next check-up.

After the operation, there is no need to stay in bed. Walking, light household tasks, reading, television and outings in town are possible from the first few days, observing the precautions: no rubbing, no swimming, no dust, shield at night. Staying active helps morale and adaptation to the new vision. More intense activities resume gradually according to the intervals given.

In some situations, a night in hospital after the operation may be offered: a very elderly person living alone without possible help, a significant general illness, general anaesthesia, a complex procedure or a single eye, that is, when the other eye sees very poorly. This monitoring allows eye pressure to be checked the next day and a safe return home to be organised. Discuss your situation during the assessment so that the team can plan for it.

For the first few nights, wear the shield over the operated eye to avoid rubbing or pressing on it in your sleep. Sleep preferably on your back or on the side of the non-operated eye. If the shield bothers you, ask the team for an alternative. A slight gritty feeling on waking is normal; a few drops of artificial tears relieve it. Keep your morning drops within reach, and turn on a soft light if you get up at night, as depth perception may be slightly disturbed.

Regimens vary between centres; some use combined eye drops or an injection at the end of the operation that reduces the number of drops. Follow the exact prescription, even if the eye feels fine, and do not stop the anti-inflammatory abruptly without advice.

• Wash your hands.
• Tilt your head back or lie down.
• Gently pull the lower eyelid down.
• Let a drop fall into the small pocket formed, without touching the eye with the tip.
• Close the eye gently for one to two minutes, without squeezing.
• Wait five minutes before another eye drop.

If your hands shake or you find it difficult, an eye-drop aid sold in pharmacies, a relative or a home nurse can help. Correct use is important to prevent infection and inflammation.

The next day, vision is often already much better, with an impression of brightness and vivid colours. It may remain slightly blurred for a few days if the cornea has swollen, which is more common after a dense cataract. Some patients see small reflections or a crescent-shaped shadow at the side; these generally disappear within a few weeks.

Vision stabilises within two to four weeks. If it deteriorates after an initial improvement, or if pain appears, seek advice promptly. Years later, a gradual decline may indicate posterior capsule opacification, which is easy to treat.

After the operation, many patients find that white looks slightly bluish and that light is intense. This is explained by the disappearance of the yellowish filter formed by the clouded lens: the brain, used to yellowed colours for years, now perceives the full palette. It adapts within a few days to a few weeks. Between the operations on the two eyes, the difference in tint between the eyes is particularly striking.

In the first few days, the pupil may remain slightly dilated and the eye more sensitive to light. Sunglasses outdoors and dimmed lighting at home improve comfort. This sensitivity decreases quickly. If it is accompanied by increasing pain or a drop in vision, contact the centre, as it may indicate inflammation.

Night glare is one of the most troublesome symptoms of cataract, particularly for driving. After the operation with a monofocal implant, most patients notice a clear improvement: headlights cause much less glare and contrast is better. With a multifocal implant, halos around lights may appear and generally diminish over time. If night vision remains troublesome, a check-up can look for dryness, a small residual correction or posterior capsule opacification.

Between the operations on the two eyes, your glasses prescription no longer suits the operated eye, while it is still needed for the other. Several solutions exist: removing the lens over the operated eye, wearing simple off-the-shelf reading glasses for reading, or using a contact lens on the non-operated eye. The optician or ophthalmologist will advise you on the most practical solution. Final glasses are made once both eyes have been operated on and have stabilised.

Older people who live alone can perfectly well be operated on as day surgery, provided the return home and the first few days are organised. A relative can drop in in the evening and the next morning, or a home help and care service can be called on for the drops, on prescription. Do your shopping and prepare meals in advance, keep the drops within reach and note the centre's number somewhere visible.

If the other eye sees poorly, the first few days may require more help. The family doctor can organise the necessary support.

For older or frail people, family members play an essential role: accompanying them to appointments, helping with drops, watching for warning signs, reminding them not to rub the eye and to wear the shield at night. They can also help choose the implant by sharing what they observe of everyday difficulties. A written list of instructions and drop times, displayed in the kitchen, makes things simpler.

• "Did it hurt?" No, just a feeling of pressure and a bright light.
• "Were you asleep?" Usually not, just relaxed.
• "Can you see better?" Often from the next day, with vivid colours.
• "Do you still need glasses?" For reading, often yes with a standard implant.
• "Can it come back?" No, only the capsule can become hazy, and this is treated by laser.

• The consultation: glare at night, cataract confirmed, standard implant chosen for distance.
• The assessment: eye measurements in a few minutes, explanations about the drops and the shield.
• The day: three hours at the centre, twenty minutes in theatre, a bright light and colours, no pain.
• The evening: gritty feeling, shield, rest.
• The next day: check-up, vivid colours, clear distance vision with the operated eye.
• Three weeks: end of the drops; the other eye now looks yellow and hazy.

• Two weeks after the first eye: operation on the second, same procedure.
• The first week: balanced vision, off-the-shelf reading glasses for reading.
• One month: final check-up, prescription of final reading glasses.
• Six months: back to night driving, no more trouble with headlights.
• Two years: hazy vision in one eye, posterior capsule opacification treated by laser in five minutes.

• Three years after the operation: vision in the right eye gradually becomes hazy again, with glare in the sun.
• The consultation: capsule opacification confirmed, laser scheduled for the following week.
• The day of the laser: dilation, two minutes in front of the device, no pain.
• The next day: vision clear again, a few small floating specks.
• One week: normal check-up, no further treatment needed.

Many patients describe a real rediscovery: brighter colours, white that looks almost bluish at first, regained brightness, less glare at night. Reading, television, recognising faces and getting around become easier. Some resume night driving, golf or hiking that they had given up.

It sometimes takes a few weeks to get used to the new vision, particularly between the operations on the two eyes. With an implant set for distance, reading glasses become essential for reading, which is good to anticipate.

About four weeks after the last operation, vision is stable and the ophthalmologist or optometrist can prescribe final glasses. With monofocal implants set for distance, you choose according to your needs between simple reading glasses, varifocal lenses for all distances, or glasses dedicated to screen work. If a small distance correction persists, it can be incorporated into varifocal lenses.

Do not have your final glasses made too early, before stabilisation: the prescription could still change by a fraction of a dioptre. In the meantime, off-the-shelf reading glasses will do.

With monofocal implants set for distance, there are two main options for near vision. Simple reading glasses are inexpensive and give a wide reading field, but you have to put them on and take them off. Varifocal lenses correct all distances in a single pair, which is practical day to day, but require an adaptation period, particularly on stairs. Glasses dedicated to screen work suit those who work at a computer for long periods.

Your optician helps you choose according to your activities. People who already wore varifocals before the operation generally adapt very quickly to their new glasses.

For adults, basic insurance does not in principle cover glasses, except in particular situations provided for by the regulations. Some supplementary insurance policies contribute to lenses and frames, sometimes every two or three years. After cataract surgery, check with your insurer before buying your final glasses, and keep the prescription and invoice.

Travelling by train or as a passenger in a car is possible from the first few days. For a longer trip, generally wait until the first-week check-up and take your drops, the shield and the operative report. Stays at altitude pose no problem, but intense light and dry air call for sunglasses and artificial tears. Avoid skiing and activities with a risk of falling for about two weeks.

During the first two weeks, keep your pets from sleeping near your face or licking it, and wash your hands after stroking them, before using your drops. Gardening, dusty DIY and cleaning with irritating products should be avoided during this period, or done with protective glasses. These precautions reduce the risk of infection.

After sixty, a regular eye examination, every one to two years, is recommended, even without particular difficulty. It allows screening not only for cataract but also for glaucoma and macular degeneration, which often progress silently. People with diabetes must have their retina examined every year. After cataract surgery, this follow-up remains necessary, as the implant does not protect against these other diseases.

For patients still working, screen work is generally possible after a few days, with regular breaks. Still-blurred intermediate vision or a difference between the two eyes can be tiring in the first few days; temporary glasses suited to screen distance help. Jobs exposed to dust, heat or physical exertion require one to two weeks off.

The first check-up, the next day or in the following days, checks eye pressure, inflammation, corneal clarity and the position of the implant. A second check-up, three to six weeks later, assesses vision, healing and the absence of macular swelling, and allows final glasses to be prescribed. In between, contact the centre if you have a worrying symptom.

After that, follow-up can be provided by your usual ophthalmologist, at a frequency suited to your age and any other eye diseases.

• The implant card, with its model and power, for each eye.
• The operative report.
• The assessment measurements, useful for any later correction.
• The prescription for your final glasses.
• Insurance statements and invoices for supplements.

Sometimes the ophthalmologist who usually follows you does not perform surgery and refers you to a colleague. In that case, the surgeon carries out the pre-operative assessment, the operation and the first check-ups, then refers you back to your usual ophthalmologist for subsequent care. This collaboration is common and works well, provided the reports are shared. Do not hesitate to ask for a copy to be sent to each.

After the operation, driving resumes when vision, with or without glasses, meets the legal requirements and the ophthalmologist has confirmed it. With one eye operated on and the other still affected, binocular vision may be unbalanced: be careful, avoid night driving and long journeys. Once both eyes have been operated on, many patients find night driving much more comfortable, without the glare that bothered them.

In winter, the sun is less intense and swimming is not on the agenda, which simplifies the precautions of the first few weeks. However, heating dries the air and ice increases the risk of falling during the period when vision is not yet balanced. In summer, strong light and the temptation to swim require more vigilance, but long days make getting around easier. Choose the period that suits your arrangements and those of the people close to you.

During the period when only one eye has been operated on, or if vision remains blurred for a few days, the perception of distance and depth may be disturbed. A few adjustments limit the risk of falling: good lighting on stairs and in corridors, night lights, removing slippery rugs, everyday items stored within reach, stable shoes. These measures are particularly useful for older people living alone.

For many patients, cataract surgery is experienced as a visual rebirth: colours, light and details regain their brilliance. This benefit is all the more marked because the cataract developed slowly, without the person realising how much their vision had deteriorated. Patients often say it feels as if the windows of their house have been replaced.

Many patients are active retirees: travel, hiking, grandchildren, volunteering, sport, reading. Cataract surgery often allows them to continue or resume these activities in better conditions. It is useful to plan the operation around planned trips and important commitments, allowing about a month for both eyes and the prescription of final glasses.

Once both eyes have been operated on, vision becomes balanced again and depth perception improves. If both implants have been set identically, vision is symmetrical; with monovision, the brain learns to use each eye for one distance. A few weeks of adaptation are sometimes needed, particularly for stairs and driving. If difficulty persists beyond a few months, mention it at the check-up.

These intervals are indicative and may vary according to healing and your surgeon's instructions. A gradual return and listening to your body remain the best rule.

Eye make-up waits one to two weeks, with new products. Face creams can be used, avoiding the eye area in the first week. At the hairdresser's, prefer having your hair washed with your head tilted back and warn them to avoid splashes in the eye; dyes and hairsprays should be avoided near the eyes for two weeks. Beauty facials, such as salon treatments, also wait until healing is complete.

After the operation, old glasses generally no longer suit. Some people who have worn thick lenses since childhood experience this change as liberation; others are disconcerted at having to get used to reading glasses. Old frames can often be reused with new lenses, and old glasses can be donated to charities that recycle them.

Serious eye infection

It is rare, but it is the most feared complication. Reduced vision, increasing pain and a very red eye in the following days require urgent consultation.

Inflammation

Common and mild, it is treated with eye drops. Swelling of the central part of the retina can sometimes reduce vision for a few weeks.

Posterior capsule opacification

Months or years later, the capsule containing the implant may become hazy. A quick laser treatment in the consulting room restores vision.

Retinal detachment

Rare, slightly more common in highly short-sighted people. Flashes, a shower of floaters or a curtain require immediate consultation.

Operative complications

Capsule rupture, a fragment of lens falling into the eye, a decentred implant: these are rare and can be treated, sometimes with a second operation.

In the event of a sudden drop in vision, significant pain or a very red eye, seek urgent medical attention; call 144 if necessary.

After the operation, the back capsule of the lens, left in place to support the implant, may gradually become cloudy, months or years later, in some patients. Residual cells multiply on its surface and form a haze. Vision becomes blurred again, with glare, as before the operation, which often causes needless worry.

Treatment takes place in the consulting room with a specific laser: after pupil dilation, the laser opens a small window in the centre of the capsule, in a few minutes, without pain or incision. Vision improves within one to two days. Temporary floaters are common. The treatment is covered by basic insurance. Once treated, posterior capsule opacification does not recur.

Many patients worry when told they need laser treatment years after their operation, thinking that the cataract has come back or that the implant must be changed. It is simply a matter of opening the clouded capsule behind the implant, in a few minutes, in the consulting room, without incision or any anaesthesia other than drops. The implant is not touched and the result is immediate or almost.

Treatment for posterior capsule opacification takes place in the consulting room, sitting in front of a device similar to the one used for routine examinations. After drops that dilate the pupil and sometimes drops to prevent a rise in pressure, a contact lens is placed on the eye to focus the laser. You hear small clicks for one to two minutes. No pain is felt. You can go home immediately, accompanied if your pupil is dilated.

For a few days, small floating specks may be visible; they gradually disappear. Eye pressure is sometimes checked. The risk of complications is very low.

A few weeks after the operation, inflammation can cause swelling of the macula, the central area of the retina, with vision that declines or becomes distorted after an initial improvement. This is more common in people with diabetes, with a history of eye inflammation or after a complication during the operation. The prescribed anti-inflammatory drops are partly intended to prevent it.

It is diagnosed by retinal tomography and treated with anti-inflammatory drops, sometimes injections. It resolves in the vast majority of cases within a few weeks to a few months. This is one of the reasons for following the treatment carefully and reporting any secondary drop in vision.

The day after the operation, eye pressure may be temporarily high, because of the gel used during the procedure or inflammation. It is measured at the first check-up and is easily corrected with drops or tablets if necessary. Later, cortisone drops can increase pressure in some people; that is why pressure is checked at subsequent visits.

Very high pressure can cause pain, headaches and nausea: you must then call the centre without delay.

Infection inside the eye, called endophthalmitis, is the most feared complication of cataract surgery. It is very rare thanks to rigorous disinfection, antibiotics injected at the end of the operation in many centres, and post-operative precautions. It generally occurs in the following days, with increasing pain, redness, rapid loss of vision and sometimes discharge.

It is an absolute emergency, requiring treatment the same day, with samples and injection of antibiotics into the eye. Treated quickly, it leaves fewer after-effects. Never ignore pain that increases after the operation.

Despite the precision of the measurements and formulas, the vision obtained may deviate slightly from the target: slight myopia, slight hyperopia or residual astigmatism. Usually this difference is minimal and corrected with light glasses. If it is significant and troublesome, several solutions exist: laser on the cornea, an additional implant placed in front of the first or, rarely, implant exchange.

These corrections are discussed once vision is stable, generally after a few weeks. For the second eye, the surgeon takes the result of the first into account to refine the calculation.

After cataract surgery, it is common to notice more small moving spots in the visual field, partly because vision has become clearer. These floaters are generally harmless. However, the sudden appearance of a shower of floaters, flashes of light or a curtain covering part of the visual field can signal a retinal tear or detachment, and requires a consultation the same day.

The incisions, eye drops and inflammation can temporarily worsen dryness of the eye surface, with gritty or burning sensations and fluctuating vision. Older people, and especially post-menopausal women, are often already prone to dryness. Preservative-free artificial tears, warm compresses on the eyelids and good hydration bring relief. Dryness generally improves within a few weeks.

Studies of operated patients show a significant improvement in vision, quality of life and independence in the vast majority. Serious complications are rare, and posterior capsule opacification, the most common, is treated simply. The most satisfied patients are those whose expectations about glasses had been clearly discussed before the operation.

Cataract patients often describe the same surprise: the procedure was shorter and simpler than they feared, and their vision the next day moved them. Many say they have rediscovered colours, reading the newspaper, their grandchildren's faces or night driving. The rare disappointments mainly concern expectations about glasses that had not been discussed enough, or another eye disease that limits the result.

• Waiting for years out of fear of the operation when the difficulty has set in.
• Choosing a premium implant without understanding the trade-offs.
• Stopping anticoagulants without instructions.
• Forgetting to mention a prostate medicine.
• Rubbing the eye or swimming in the first few weeks.
• Stopping the drops too early because the eye feels fine.
• Having final glasses made before vision has stabilised.
• Ignoring pain that increases after the operation.

When the cataract impairs vision, the procedure, anaesthesia, check-ups and a standard monofocal implant are covered by compulsory health insurance, subject to your deductible (franchise) and co-payment (quote-part). The supplement for a premium implant, toric correction or laser assistance remains at your expense; it must be announced and accepted in writing before the procedure. The operation is usually performed as day surgery. Some supplementary insurance policies contribute to the supplement.

For outpatient cataract surgery, the hospital ward category is less important than for an operation with a stay, but it can influence free choice of surgeon and certain supplements. Semi-private or private supplementary insurance often allows you to choose your surgeon and facility. Check with your insurer before the operation to find out what is covered.

For standard cataract surgery, basic insurance covers the costs, but you contribute under the usual rules: your chosen annual deductible, then a ten per cent co-payment, up to an annual ceiling. If you have chosen a high deductible, a large part of the cost of the first operation may be at your expense in the year in which it takes place.

Having both eyes operated on in the same year often limits your total contribution, as the deductible is only counted once per calendar year. This is a practical point to take into account in planning, if your medical situation allows.

For a standard operation, billing takes place directly between the facility and your insurer, which then sends you a statement for the deductible and co-payment. If you choose a premium implant, the facility bills you directly for the supplement, often before the operation. Keep the statements and check that they match the quote. Supplementary insurance may reimburse some supplements on presentation of the invoices.

If you have chosen a family doctor, care network or telemedicine model, you must generally first go through your primary care doctor or the telephone advice service before consulting the ophthalmologist. Without this step, the insurer may refuse or reduce reimbursement. Regular eye check-ups may sometimes be directly accessible. Check the terms of your policy.

Cataract surgery is performed in university eye clinics, the Jules-Gonin Eye Hospital in Lausanne, most cantonal and regional hospitals, and many equipped clinics and practices. Provision is therefore close to home in almost every canton.

In French-speaking Switzerland, cataract surgery is available in Geneva, the canton of Vaud, Neuchâtel, Jura, Fribourg and Valais, in cantonal hospitals, private clinics and many outpatient centres. The university eye hospital in Lausanne and the ophthalmology department of the Geneva University Hospitals (HUG) treat complex cases.

In German-speaking Switzerland, Bern, Basel and Zurich have university clinics, and cantonal hospitals, such as those in Aarau, Lucerne, St. Gallen or Chur, as well as many private centres, perform cataract surgery. In Ticino, Lugano, Bellinzona and Locarno provide operations, with consultations in Italian. In the small cantons, patients are often operated on in the neighbouring canton.

As check-ups are few, distance matters less than the quality of the team and the date offered. Your usual ophthalmologist can often provide follow-up after the operation.

Provision changes and some surgeons operate in several facilities. For a standard operation covered by insurance, the cost to the patient depends mainly on their deductible and co-payment rather than on the city.

Cataract surgery is performed in three types of facility. Public and university hospitals operate on basic insurance patients and treat complex cases, with a complete team on site. Private clinics often offer free choice of surgeon and greater comfort, with basic coverage supplemented by supplementary insurance depending on the ward category. Specialist outpatient centres focus their activity on eye surgery, with fast organisation.

For a simple cataract, all three options give excellent results. The choice depends on your preferences, your insurance cover, waiting times and the complexity of your situation.

• Is my cataract the only cause of my loss of vision?
• Which implant do you recommend for me, and why?
• At what distance will I see clearly without glasses?
• Will my astigmatism be corrected?
• Does my situation present any particular difficulties?
• When will you operate on the second eye?
• What will be at my expense?
• Whom should I contact if there is a problem?

A second opinion is useful if you are offered an expensive premium implant and are hesitating, if your situation is complex, or if you doubt that the cataract is the main cause of your difficulty. The assessment measurements can be passed on. For a simple cataract, the opinion of a single experienced ophthalmologist is generally enough.

Before the operation, the ophthalmologist informs you of the nature of the procedure, the expected benefits, the risks, the alternatives and any costs, then you sign a consent form. Take the time to read it and ask your questions. A relative can accompany you to this consultation.

To understand the choice of implant, the instructions for the drops and the warning signs, it is important to be treated in a language you are fluent in. In French-speaking Switzerland, everything takes place in French. In German-speaking hospitals and clinics, many ophthalmologists see patients in French, and professional interpreters can be requested. In Ticino, care is provided in Italian. Ask for written instructions in your language.

The family doctor is often the first to notice a loss of vision or to hear complaints about glare. They can refer you to an ophthalmologist, which is sometimes required by your insurance model. Before the operation, they help control diabetes or blood pressure, and manage anticoagulants in liaison with the team. After the operation, they can prescribe home help if necessary.

For any question about cataract, your ophthalmologist and family doctor are the first people to ask. Hospitals and eye centres often publish information sheets for patients. Associations supporting visually impaired people can help those whose vision remains low because of another eye disease. For home help after the operation, contact the home help and care services in your municipality or region.

• 1. Assess the difficulty in daily life: driving, reading, glare, leisure.
• 2. Have a complete examination to confirm that the cataract is the cause.
• 3. Choose the implant and target vision with the surgeon.
• 4. Organise the operations on both eyes, the people accompanying you and any help.
• 5. Prepare for recovery: drops, shield, precautions, check-ups.

Cataract surgery restores the transparency of the eye's optical system, but it does not repair a diseased retina, optic nerve or cornea. If the eye is otherwise healthy, vision generally becomes excellent again. If another disease is present, the gain is more limited, although clarity and colours often improve. With a standard implant, glasses remain necessary for certain distances. Knowing these limitations in advance avoids disappointment and allows you to fully appreciate the result.

• It does not cure macular degeneration or glaucoma.
• It does not always eliminate the need for glasses.
• It does not protect against posterior capsule opacification, which is easy to treat.
• It does not replace regular eye follow-up.
• It does not correct significant astigmatism without a toric implant.

Cataract surgery is generally not urgent. Take the time to understand the implant options, ask your questions and talk to those close to you, especially if a premium implant is being considered. A surgeon who takes time to explain, without pushing towards the most expensive option, is a good sign. Once the implant is in place, the choice is final: it deserves a few days' reflection.

The choice of implant and timing of the operation is personal, but it is often useful to discuss it with those close to you, especially if they will be asked to accompany you and help with the drops. They can also bring an outside view of your everyday difficulty, which patients sometimes underestimate. If you wish, a relative can attend the consultation to ask questions and take notes.

Your deductible and co-payment on the covered part are added to these supplements. Details on our page on cataract surgery prices in Switzerland.

A clear quote distinguishes the part covered by basic insurance from the part at your expense, eye by eye.

• Capsule: the thin envelope of the lens, kept to support the implant.
• Posterior capsule opacification ("secondary cataract"): clouding of the capsule after the operation.
• Crystalline lens: the eye's natural lens.
• Monofocal implant: an implant that gives clear vision at one distance.
• Toric implant: an implant that corrects astigmatism.
• Phacoemulsification: a technique for breaking up the lens with ultrasound.
• Zonules: the fibres that suspend the lens.
• Biometry: eye measurements used to calculate the implant.
• Macula: the central area of the retina.
• Endophthalmitis: serious infection inside the eye.

• A cataract is clouding of the lens, mainly linked to age.
• Surgery is performed when difficulty appears, without waiting for it to become advanced.
• The procedure is short, painless and performed as day surgery.
• The choice of implant determines the need for glasses after the operation.
• The operation is covered by basic insurance with a standard implant.
• Increasing pain or a sudden drop in vision require urgent consultation.

For the vast majority of patients, cataract surgery is a simple, quick and extremely beneficial procedure. It restores not only sharper vision, but also colours, light and often regained independence. Well prepared, with an implant suited to your needs and rigorous follow-up, it gives excellent, lasting results.

If you are still hesitating, an information consultation with an ophthalmologist will allow you to review your vision, understand whether the operation is useful now, and ask all your questions without obligation. It is often this discussion that allows you to decide calmly, at the right time for you. Bring your glasses, prescriptions and list of medicines: this information makes the consultation more effective and allows the ophthalmologist to advise you as well as possible, taking into account your overall health and lifestyle. Do not hesitate to come with someone close to you, who can take notes for you during the consultation.

Medespoir Suisse helps you understand the implant options, prepare your questions and find an ophthalmologist or facility suited to your situation, in your region and your language. We also help you distinguish what is covered by insurance from what remains at your expense.

Cataract surgery is one of the most effective procedures in medicine: in about twenty minutes, it restores clear vision, vivid colours and often regained independence. Choosing your implant well, following the instructions and attending the check-ups are the keys to an excellent result. For an overview, see our guide to eye surgery in Switzerland.

Answers to the most frequent questions about cataract surgery in Switzerland.

Understanding cataract

What is a cataract? A cataract is clouding of the crystalline lens, the natural lens behind the iris that allows the eye to focus. Over time, the proteins it is made of deteriorate and it loses its transparency, rather like a window becoming dull. Light passes through less well and is scattered, making vision blurred, hazy and sensitive to glare.

Is cataract a serious disease? It is not dangerous to general health and generally progresses slowly, but it gradually reduces vision and can become a real handicap in daily life, particularly for driving and reading. Left untreated for a very long time, it can make the procedure more delicate. The good news is that it is treated very effectively by short, safe surgery.

What are the first signs? Vision that becomes hazy, the impression of seeing through a dirty window, glare from headlights at night or from the sun, colours that look dull or yellowed, needing more light to read, and frequent changes of glasses without real improvement. These signs often appear on one side only at first.

Can cataract be treated without surgery? No. No eye drop, medicine, food supplement or exercise makes a cataract regress. At first, better-suited glasses and better lighting can compensate for the difficulty for a while. When the difficulty becomes significant, only surgery, which replaces the clouded lens with an implant, restores clear vision.

Does cataract affect both eyes? Usually yes, but rarely at the same pace: one eye is generally more affected than the other. The eye that is most troublesome is operated on first, then the second when it becomes troublesome in turn, often a few weeks or months later. A cataract in one eye only can also occur after injury or inflammation.

Can you get a cataract when young? Yes, although it is less common. A cataract can appear before fifty with diabetes, long-term cortisone treatment, high myopia, eye injury, chronic inflammation or after certain retinal surgery. There are also congenital cataracts in children, which must be operated on quickly.

Should you wait until it is "ripe"? No, that is an old idea. Nowadays, there is no longer any wait for a cataract to become very advanced: surgery is performed when the problem affects daily life. A cataract that is too dense is even more difficult to operate on, requires more ultrasound energy and carries a higher risk of complications. It is therefore pointless, even counterproductive, to wait.

Can cataract come back? No, as the lens has been removed, the cataract cannot recur. However, months or years later, the capsule that holds the implant may become cloudy: this is posterior capsule opacification, or "secondary cataract". It causes similar symptoms but is treated very simply, in a few minutes, with a laser in the consulting room.

Does sunlight encourage cataract? Yes. Prolonged exposure to ultraviolet light, particularly in the mountains and on snow, is a recognised risk factor. Wearing UV-filtering sunglasses and a hat outdoors, from an early age, helps protect the lens. Modern implants also filter ultraviolet light after the operation.

Does smoking encourage cataract? Yes, smoking is one of the modifiable risk factors for cataract, along with sun exposure. It also increases the risk of macular degeneration. Stopping smoking is beneficial to eye health at any age, and also helps healing after a procedure.

Does cataract affect driving? Often, and it is even one of the first reasons for seeking advice: glare from headlights, difficulty reading signs, less sharp vision at dusk. Driving requires a minimum visual acuity set by the regulations. If your vision no longer meets these requirements, you must stop driving until the operation.

Does diabetes accelerate cataract? Yes. Diabetes encourages earlier onset and faster progression of cataract. People with diabetes must also have their retina monitored, as diabetic retinopathy can influence the result of the operation and require treatment before or after. Well-controlled diabetes is preferable before the procedure.

Do corticosteroids encourage cataract? Yes, long-term cortisone treatment, in tablets, high-dose inhalers or drops, can cause a cataract, often of a particular form that quickly impairs reading and vision in bright light. If you are on such treatment, regular eye check-ups are useful. Never stop a treatment without medical advice.

Does cataract cause pain? No, an ordinary cataract is painless. Eye pain, redness or a sudden drop in vision should prompt a search for another cause, such as acute glaucoma or inflammation, and justify a prompt consultation.

Can you see double with one eye? Yes, cataract can cause double vision or ghost images even when the other eye is closed, as the clouded lens diffracts light irregularly. This symptom disappears after the operation. Double vision that disappears when one eye is closed, on the other hand, has another cause, often muscular or neurological, and must be investigated.

Does cataract change colour perception? Yes. The clouded lens yellows and acts as a filter: colours look dull, and blues and violets less vivid. After the operation, many patients are struck by the brightness and vividness of colours, sometimes to the point of finding white almost bluish in the first few days.

Can myopia increase because of cataract? Yes. Some cataracts in the centre of the lens increase its power and make the eye more short-sighted. An older person may then find that they can read again without glasses while their distance vision deteriorates. This rapid change in prescription is a classic sign of nuclear cataract.

Can an injury cause a cataract? Yes. A violent blow to the eye, a penetrating wound or certain radiation exposures can cause a cataract, sometimes months or years later. These cataracts often affect one eye only and may be accompanied by other injuries, which are assessed before the operation.

How is cataract diagnosed? The ophthalmologist measures vision, then examines the lens under the microscope after dilating the pupil with drops. They assess the type and density of the cataract and examine the retina and optic nerve to check that the loss of vision has no other cause. The examination is painless; vision remains blurred for a few hours after dilation.

Does cataract cause blindness? In countries where access to surgery is limited, cataract remains a major cause of blindness. In Switzerland, thanks to accessible and effective surgery, it no longer causes permanent blindness: even a very advanced cataract can be operated on and vision restored, if the rest of the eye is healthy.

The operation

How is the operation performed? After anaesthetic and dilating drops, the surgeon makes small incisions at the edge of the cornea, opens the lens capsule, breaks up the lens with ultrasound and aspirates the fragments. They then insert a foldable implant into the capsule left in place, where it unfolds. The procedure is performed under the microscope, with you lying down and the eye held open by a small speculum.

How long does it take? The procedure itself generally takes ten to twenty minutes. Including preparation, positioning and post-operative monitoring, you spend about two to four hours at the centre or hospital. You go home the same day.

Is it painful? No. Anaesthetic drops, sometimes supplemented by a small injection of anaesthetic into the eye, eliminate pain. You may feel slight pressure, see lights and colours, and hear the noise of the device. After the operation, discomfort or a gritty sensation is common for a few hours, rarely real pain.

Will I be asleep? Generally not: the operation is performed under local anaesthesia, often with light sedation to help you relax. You remain conscious, which allows you to follow instructions such as looking at the light. General anaesthesia is reserved for particular situations, such as patients who cannot stay still, or children.

Are both eyes operated on the same day? Usually not: one eye is operated on, then the second a few days to a few weeks later. This allows the result of the first eye to be checked, the choice of implant for the second to be adjusted if needed, and the very low risk of a complication affecting both eyes to be limited. Some centres offer same-day surgery on both eyes to selected patients.

Do I need to stay in hospital? No, in almost all cases the operation is performed as day surgery: you arrive in the morning and go home a few hours later, accompanied. A short hospital stay may be considered for very elderly patients living alone, in the event of a significant general illness, or with general anaesthesia.

What is phacoemulsification? It is the reference technique for cataract surgery. A probe vibrating at a very high frequency, inserted through an incision of two to three millimetres, breaks the lens into small pieces while aspirating them. The small size of the incisions allows quick recovery and, usually, no stitches.

Is laser better? Some centres use a femtosecond laser to make the incisions, open the lens capsule and pre-cut the lens. It brings great precision to certain steps, but studies have not shown clear superiority over the manual technique for most patients. It involves an extra cost, generally at the patient's expense. Your surgeon will tell you whether it is of interest in your case.

Are stitches needed? Usually not. The incisions are so small and constructed so tightly that they close on their own, through the pressure of the eye. A stitch may sometimes be placed for a larger incision or in a particular situation; it is then removed or dissolves.

Can I move during the operation? You must stay as still as possible, but the team guides you throughout and warns you before each step. A speculum holds the eyelids open, so you do not need to fight blinking. If you need to cough or sneeze, simply tell the surgeon, who will pause.

Is an assessment needed beforehand? Yes. The assessment includes measuring the length of the eye and the curvature of the cornea, which are essential for calculating the implant power, examination of the retina and optic nerve, and sometimes other tests such as macular tomography. It also allows the implant to be chosen and the target vision to be discussed.

Should I stop my anticoagulants? Usually not. Cataract surgery involves no significant bleeding, and most anticoagulants and antiplatelet drugs can be continued. Never change your treatment on your own: follow the instructions of the ophthalmologist and anaesthetist, in liaison with the doctor who prescribed the treatment.

Can I have surgery if I have glaucoma? Yes. Cataract surgery can even lower eye pressure in some glaucomas, particularly those linked to a narrow angle. It can be combined with minimally invasive glaucoma surgery at the same time. The surgeon adapts the choice of implant: multifocal implants are generally not advised with advanced glaucoma.

Can I have surgery if I have retinal disease? Yes, but the visual result will depend on the condition of the retina. With macular degeneration, diabetic retinopathy or macular oedema, the operation improves the clarity of vision, but fine vision may remain limited. The retinal disease must be stabilised and monitored before and after the procedure.

Is previous LASIK a problem? Not for the operation itself, but calculating the implant power is more delicate, as the shape of the cornea has been changed. Surgeons have specific formulas. If you have kept your measurements from before LASIK, bring them: they greatly improve the precision of the calculation.

What is a capsule rupture? It is the most common intra-operative complication, although rare: the very thin lens capsule tears during the procedure. The surgeon then adapts the technique, places the implant in another location or position, and if necessary removes some of the vitreous. The final result remains good in most cases, sometimes with slower recovery.

Is the implant permanent? Yes. The implant is designed to last a lifetime, without maintenance or replacement. It does not wear out or become cloudy. Only the capsule surrounding it can become cloudy later, which is treated by laser without touching the implant.

Can the implant be changed later? It is possible but rarely necessary, and more delicate over time, as the implant becomes fixed in the capsule. An exchange may be considered in the event of a significant calculation error, intolerance of a multifocal implant or displacement. To correct a small error, glasses, corneal laser or an additional implant are often preferred.

Is surgery possible at a very advanced age? Yes. Age is not a contraindication: patients aged ninety and over are operated on successfully. The procedure, short and under local anaesthesia, is very well tolerated. It often greatly improves the independence, safety when moving around and quality of life of older people.

Do I need to fast? It depends on the type of anaesthesia and the centre. For simple local anaesthesia, a light meal is often allowed; if sedation is planned, you may be asked to fast for a few hours. Follow the instructions received precisely, and take your usual medicines unless told otherwise.

Implants

What is a monofocal implant? It is the standard implant, covered by basic insurance. It gives clear vision at one chosen distance, generally for distance. Near vision, and often intermediate vision, then require reading glasses. It offers excellent quality of vision and contrast, without particular halos, and suits the vast majority of patients.

What is a toric implant? It is an implant that also corrects corneal astigmatism. It must be positioned along a precise axis, marked before the procedure. It clearly improves vision without glasses in people with significant astigmatism. Its extra cost compared with the standard implant is generally at the patient's expense.

What is a multifocal implant? It is an implant that divides light between several focal points, to see at distance, intermediate and near. It allows many patients to do without glasses in daily life. In return, it can cause halos around lights at night and a slight loss of contrast. It does not suit every eye.

What is an extended depth-of-focus implant? It is an implant that extends the range of sharp vision, from distance to the distance of a computer screen, with fewer halos than a multifocal implant. Light glasses often remain useful for reading small print. It is a compromise appreciated by patients who drive a lot at night and use a computer.

What is monovision? Monovision involves setting one eye for distance vision and the other for intermediate or near vision, with monofocal implants. The brain uses the eye suited to each distance. It can reduce the need for glasses without the drawbacks of multifocal implants, but not everyone adapts to it; a prior trial is advisable.

Do premium implants have drawbacks? Yes: multifocal implants can cause night halos and glare and a loss of contrast, and require an adaptation period. They are not advised with macular disease, advanced glaucoma or severe dry eye. Their extra cost is generally at the patient's expense. A premium implant is not necessarily the best choice for everyone.

Which implant for a night driver? People who drive a lot at night often favour a monofocal or extended depth-of-focus implant, which cause few or no halos. A multifocal implant can impair night driving, especially in the first few months. Tell the surgeon about your driving habits.

Which implant for a keen reader? A keen reader can choose a monofocal implant set for distance and wear reading glasses, or opt for monovision or a multifocal implant to read without glasses. Some even prefer a slightly short-sighted setting in both eyes to read without glasses and wear glasses for driving. The choice depends on your priorities.

Are implants reimbursed? The standard monofocal implant is covered by basic insurance with the operation. For toric, multifocal or extended depth-of-focus implants, the price difference and additional tests are generally at the patient's expense. Ask for a quote that clearly separates the covered part and the part to be paid.

Can different implants be chosen for each eye? Yes. The surgeon can combine different implants or different settings for the two eyes, for example with monovision, or adapt the second implant according to the result of the first. This strategy is discussed according to your needs and tolerance.

Do implants block ultraviolet light? Yes, current implants filter ultraviolet light, as the natural lens did. Some also filter part of the blue light. Wearing sunglasses remains recommended outdoors, particularly in the mountains, for comfort and to protect the eye surface.

Can the implant move? Rarely. An implant can decentre or rotate in the first few days, which is more troublesome for a toric implant and may require repositioning. Years later, an implant can shift if the fibres that hold the capsule are fragile. A sudden drop in vision requires medical attention.

Can the implant be felt? No. The implant is placed inside the eye, where the lens was, and cannot be felt. It is invisible from the outside. Some people occasionally notice a slight reflection or shadow at the edge of the visual field in the first few weeks; this generally disappears with time.

Can I have an MRI with an implant? Yes. Cataract implants contain no metal and pose no problem for an MRI, CT scan or security checks. There is no need to mention them for these tests, but it is useful to mention the operation to any ophthalmologist.

Will I still need glasses afterwards? With a monofocal implant set for distance, reading glasses are needed, and sometimes a small distance correction. With a multifocal or extended depth-of-focus implant, many patients do without glasses day to day, sometimes with glasses for prolonged reading or small print. Final glasses are prescribed a few weeks after the operation.

How do I choose? The choice is made with the surgeon, based on your activities, priorities, the condition of your eyes and your budget. Ask yourself at which distances you want to see without glasses, whether you drive a lot at night, and whether you are prepared to accept halos. There is no ideal implant for everyone, but there is a suitable implant for each person.

Can monovision be tested? Yes, with contact lenses set as the implants would be, for a few days. This test helps you know whether you tolerate the difference between the two eyes. It is not always possible in patients with an advanced cataract, but it is useful for those who already wear contact lenses.

Will astigmatism be corrected? Slight astigmatism can be reduced by the position of the incisions. More significant astigmatism is corrected by a toric implant, at an extra cost. Without correction, it persists after the operation and requires glasses. The assessment measures corneal astigmatism precisely so that the suitable option can be proposed.

Do implants age? No. Current materials are stable and do not deteriorate over time. They remain transparent for life. The rare cases of clouding of certain old implants do not concern the models used today.

Is a premium implant always better? No. A premium implant offers more independence from glasses, but at the cost of trade-offs and an extra charge. For many patients, a well-calculated monofocal implant, with reading glasses, gives the best quality of vision. The best implant is the one that suits your eyes and your lifestyle.

Recovery and risks

When will I see better? Often from the next day, with clearer vision and brighter colours. Vision may remain slightly blurred for a few days, particularly if the cataract was dense or if there is swelling of the cornea. It stabilises within two to four weeks.

How long is the recovery period? Recovery is quick: most daily activities resume within a few days. Precautions, such as drops, the shield at night, no rubbing and no swimming, last two to four weeks. Vision is stable at about one month, when final glasses can be prescribed.

When can I drive? Not on the day of the operation. You can drive again when your vision meets the legal requirements, often after a few days, and with the ophthalmologist's approval. If the other eye has not yet been operated on, the difference between the two eyes can be troublesome; be careful or wait for the second operation.

When can I go back to work? For office work, often after a few days to a week. Physical jobs, those exposed to dust or requiring heavy lifting require one to two weeks, sometimes more. Your ophthalmologist will issue a suitable certificate.

Are eye drops needed? Yes. Antibiotic and anti-inflammatory drops are prescribed for several weeks, on a tapering schedule. They prevent infection and inflammation and promote good healing. It is important to use them regularly, even if the eye feels fine, and to ask for help if you find it difficult.

Can I watch television? Yes, from the same day or the next day. Television, reading and screens do not harm the operated eye. They may be tiring in the first few days; take breaks. Near vision may require temporary glasses while waiting for the final ones.

Can I bend down? Everyday movements, including bending down briefly, are allowed. Avoid heavy exertion, lifting heavy loads and prolonged head-down positions for one to two weeks, as well as rubbing the eye. These precautions limit pressure in the eye while it heals.

When can I go to the swimming pool? It is advisable to avoid swimming pools, swimming in lakes or the sea, jacuzzis and the sauna for two to four weeks, because of the risk of infection. After that, swimming goggles can be worn as a precaution for a few more weeks.

What are the main risks? The most common are posterior capsule opacification, temporary inflammation, a temporary rise in eye pressure, swelling of the macula, a residual refractive error and dry eye. Serious complications, such as serious infection or retinal detachment, are rare. Follow-up and drops allow them to be prevented or treated early.

Which signs should alert me? Increasing pain, increasing redness, a drop in vision after an initial improvement, discharge, or the appearance of flashes of light, many floaters or a curtain in the visual field. In these cases, contact the centre or an eye emergency department immediately.

What is posterior capsule opacification ("secondary cataract")? It is the gradual clouding of the thin capsule that holds the implant, months or years after the operation. Vision becomes hazy again, as before the operation. It is treated in the consulting room with a laser that opens a window in this capsule, in a few minutes, without pain or incision. Vision improves from the next day.

Is retinal detachment common? It is rare, but slightly more common after cataract surgery, especially in highly short-sighted people and young men. It shows as flashes, a shower of floaters or a curtain spreading across the visual field, and requires urgent consultation. Treated quickly, it has good results.

Can the eye be dry afterwards? Yes, temporary dryness is common, linked to the incisions and eye drops. It is treated with artificial tears and improves within a few weeks. People who already had dry eyes before the operation may feel it more and benefit from preventive treatment.

Do halos disappear? With a monofocal implant, halos are rare and temporary. With a multifocal implant, they are more common and generally fade within a few months as the brain adapts. If they persist and are troublesome, the ophthalmologist looks for the cause, such as posterior capsule opacification or dryness, which can be treated.

Do I need new glasses? Yes, usually. The prescription changes after the operation. Final glasses are generally prescribed three to four weeks after the last operation, once vision is stable. In the meantime, temporary reading glasses can help.

Are complications covered? Yes. As cataract surgery is a basic insurance benefit, treatment of its complications, such as laser for posterior capsule opacification or a further operation, is also covered under the usual deductible (franchise) and co-payment (quote-part) rules.

How many check-ups are needed? Generally a check-up the next day or in the following days, then a check-up at around three to six weeks. Additional check-ups may be needed with an associated disease, such as glaucoma or retinopathy. Follow-up can then be provided by your usual ophthalmologist.

Can I sleep on my side? It is advisable not to sleep on the side of the operated eye during the first week, and to wear the protective shield at night. Sleeping on your back or on the non-operated side avoids pressing on the eye and rubbing it inadvertently.

Can I wear make-up? Eye make-up is not advised for one to two weeks, to avoid the risk of infection. Then use new products, particularly mascara and eye pencil, and remove make-up gently, without rubbing. The rest of the face can be made up from the next day, avoiding the eye area.

Is the result permanent? Yes. The implant remains in place for life and the cataract cannot recur. Vision may, however, change with other age-related conditions, such as macular degeneration or glaucoma, or with posterior capsule opacification, which is easily treated. Regular eye follow-up remains recommended.

Organising in Switzerland

Is the operation reimbursed? Yes. When the cataract impairs vision, the operation with a standard implant is covered by basic insurance, under the usual deductible (franchise) and co-payment (quote-part) rules. Supplements for premium implants, femtosecond laser or certain additional tests generally remain at the patient's expense.

How much will I pay? With a standard implant, you pay your annual deductible if it has not yet been reached and the ten per cent co-payment, up to the annual ceiling. If you choose a premium implant, the supplement is added. Ask for a detailed quote specifying the covered part and the part at your expense.

Is prior approval needed? For standard cataract surgery, no prior approval from the insurer is generally needed. Depending on your insurance model, you may have to go through your family doctor or a care network first to be referred to the ophthalmologist. Check the terms of your policy.

Where can I have the operation? In most cantons, in cantonal and university hospitals, private clinics and many outpatient eye centres. The Jules-Gonin Eye Hospital in Lausanne and the university clinics treat complex cases. Your ophthalmologist can recommend a surgeon or facility.

Are waiting times long? They vary between regions and facilities, from a few weeks to a few months. If your difficulty is significant, for example for driving or safety, mention it: the wait can sometimes be shortened. Comparing several facilities can also help you get an earlier date.

Can I have the operation in another canton? Yes. Free choice of facility applies: you can choose a hospital on a cantonal hospital list outside your canton. Coverage may then be limited to the tariff of your canton of residence, with any difference covered by supplementary insurance or at your expense. Find out beforehand.

Do I need someone with me? Yes, on the day of the operation, as you will not be able to drive and your vision will be blurred. Someone accompanying you is also useful for the first check-up the next day. For people who live alone, having someone present or visiting on the first night is reassuring.

Can I be treated in my own language? In French-speaking Switzerland, everything takes place in French. In German-speaking hospitals and large clinics, many ophthalmologists speak French or English, and interpreters can be requested. In Ticino, care is provided in Italian. When choosing the implant, it is important to understand the explanations fully.

Can my family doctor help? Yes. They can refer you to an ophthalmologist, control diabetes or blood pressure before the operation, manage your anticoagulant treatment in liaison with the team, and organise home help if necessary. Tell them the date of the operation.

How can I get a personalised opinion? By consulting an ophthalmologist for a complete examination. You can also tell us your age, symptoms, eye history and expectations about glasses: we will direct you to a suitable surgeon or facility, in your region and your language.

How many days off are needed? For office work, often a few days to a week per operated eye. For a physical job or one exposed to dust, one to two weeks. As many patients are retired, the question is mainly about organising help and transport.

Is supplementary insurance useful? Supplementary insurance can cover free choice of surgeon and a room in the private or semi-private ward, an operation outside your canton, and sometimes part of the extra cost of a premium implant. Conditions vary greatly; check your policy and ask for written confirmation.

What should the quote specify? The type of implant and any supplement, whether or not a femtosecond laser is used, additional tests billed separately, the number of check-ups included, and the split between what is covered by insurance and what remains at your expense.

Should I keep my documents? Yes. Keep the operative report and the implant card, which shows its model and power. This information is useful in the event of a problem, for future laser treatment of posterior capsule opacification, or if you consult another ophthalmologist.

Are both eyes operated on at the same place? Generally yes, by the same surgeon, to ensure consistency in the choice of implants and follow-up. It is possible to change facility between the two eyes, but all the measurements and the report on the first eye must then be passed on.

Should I arrange home help? For most patients, help is only needed on the day of the operation and the next day. Very elderly people, those living alone or having difficulty using the drops can benefit from home visits by a nurse, prescribed by the doctor and covered by basic insurance.

Which season should I choose? There is no mandatory season. Some prefer to avoid summer, so as not to give up swimming and intense sun, or the pollen season if they have allergies. The main thing is to choose a period when you can attend the check-ups and avoid long trips in the first few weeks.

Is the consultation reimbursed? Yes. Consultations and tests related to the diagnosis and preparation of cataract surgery are covered by basic insurance under the usual rules. Some additional tests needed only for a premium implant may be billed separately.

Can several centres be compared? Yes. You can compare the surgeons' experience, the implants offered, waiting times, how check-ups are organised and any supplements. For a covered operation, price differences mainly concern options and the hospital ward category.

What should I do if there is a problem at the weekend? Before the operation, ask for the number to call outside opening hours. In the event of intense pain, significant loss of vision or increasing redness, and if the centre cannot be reached, go to an eye or general emergency department, mentioning your recent operation.
