What is a refractive lens exchange?

Refractive lens exchange is when the eye's natural lens is replaced with an artificial lens (IOL, intraocular lens). The procedure corrects presbyopia or severe ametropia and is an excellent alternative to laser eye treatment. It creates lifelong independence from reading glasses or varifocals and prevents cataracts common in old age.Various lens types are available for the procedure. Our premium lenses are multifocal lenses which enable clear vision for both near and far - experience a whole new level of freedom and quality of life.

Preliminary examination

Firstly, we examine your visual acuity and corneas during a free, no-obligation, 30-minute preliminary examination to determine if a refractive lens exchange is viable.


Main examination

During the 45-minute, free, no-obligation main examination, our ophthalmologists thoroughly examine and measure your eyes to determine the strength and type of lens you need.

Firstly, we anaesthetise your eyes with drops. Then, we gently remove your natural eye lens through a tiny opening in the side of the cornea and insert the artificial lens. The entire procedure takes approximately 10 minutes and is entirely pain-free.

Frequently Asked Questions

These are the most important and frequent questions and answers about betterview. If you can't find the answer to your question here, please get in touch with us.

Laser eye surgery or lens exchange?

Whether laser eye treatment or refractive lens exchange is best for your vision correction depends on various factors. However, if you are over 45 and want to correct presbyopia, refractive lens exchange is probably better because it prevents the progression of presbyopia.

What ages are suitable for a lens exchange?

We use refractive lens exchange to correct presbyopia for people over 45. However, in some cases, we also use the treatment to correct severe, non-age-related ametropia, which we can carry out as soon as you are over 18.

How long does an artificial eye lens last?

Artificial lenses are permanent and last a lifetime. We use refractive lenses to replace your eye's natural lenses and prevent further ametropia and lens clouding (cataracts), enabling clear vision throughout old age.

What are the risks associated with lens exchange?

Refractive lens exchange is a proven and safe method for treating presbyopia. If your vision deviates from the desired result afterwards, we can correct it with laser eye treatment. We also treat the rare cases of eye infection that occur after the procedure.

How much does refractive lens exchange cost?

betterview charges CHF 4,980 per eye for refractive lens exchange, which you can pay immediately or in convenient instalments. Our flat rate includes the preliminary and main examinations, the procedure and follow-ups. Thanks to the betterview warranty, you'll only be charged if we perform the procedure.

What can I expect after treatment?

The eye recovers significantly in the first 24 hours after the procedure, and visual acuity gradually improves. However, it may take several weeks to achieve optimal and stable vision. As a rule, you can resume your usual activities the day after, but you should limit them to a reasonable level. Strenuous activities should be avoided to allow the eyes to rest and recover.
