In brief

Trifocal lenses: three distances, procedure and costs

The trifocal lens is an artificial lens with three focal points for near (about 40 cm), intermediate and distance vision, which replaces your own natural lens in a refractive lens exchange. At EyeLaser Zurich, a refractive lens exchange with a trifocal lens costs CHF 5’000 per eye; for cataract, the surcharge is CHF 2’700. The procedure takes about 15 minutes per eye.

  • One system for all distances: three clearly defined focal points for near, intermediate (e.g. screen) and distance.
  • Largely without glasses in daily life: In studies, people with trifocal lenses read up close without glasses more often than with EDOF lenses (Tavassoli 2024); in low light, reading glasses may still be needed for small print.
  • Permanent: made to stay in the eye; a cataract can no longer develop afterwards.
  • Gentle procedure: precise planning and a minimally invasive outpatient procedure.

How the trifocal lens works – vision at three distances

Trifokallinse
  • Near (≈ 40 cm): smartphone, book, labels.
  • Intermediate (≈ 60–80 cm): notebook, stovetop, conversations.
  • Distance (from ≈ 1 m): road, sports, landscape.

The optic distributes the light across these ranges. The brain adapts during the first weeks to months (neuroadaptation; Rosa 2017). Halos around lights are more frequent with trifocal lenses than with monofocal lenses (de Silva 2016) and usually decrease during this time. Contrast and night vision gradually improve as well.

Who implants the trifocal lens at EyeLaser Zurich?

Dr. Victor Derhartunian
  • Refractive lens exchange: depending on the case, Dr. med. univ. Victor Derhartunian, Dr. med. Myron Kynigopoulos or Dr. med. Valery Vinzent Wittwer; Dr. Derhartunian is the medical director and oversees all findings and measurement data.
  • Cataract: our highly specialised team led by Dr. Kynigopoulos.
  • Measurement and planning: MS-39 (CSO) and Anterion (Heidelberg) for the cornea, biometry and lens calculation; a toric lens if you have astigmatism.
  • Location: Strehlgasse 33, 8001 Zürich – a five-minute walk from the Urania car park.

The price depends not on the lens but on your situation. Three cases, three clear answers.

Cataract with basic insurance: We bill the operation to your basic insurance under the TARDOC tariff. For an EDOF or multifocal lens you pay a surcharge of CHF 2,700 per eye, plus CHF 1,000 with the femtosecond laser. All cataract surcharges

Lens exchange without cataract: Refractive lens exchange without cataract costs CHF 5,000 per eye, CHF 6,000 with the femtosecond laser — regardless of which implant is used. Refractive lens exchange

Cataract as a self-payer: Without Swiss basic insurance, cataract surgery is priced like lens exchange: CHF 5,000 per eye, CHF 6,000 with the femtosecond laser.

For comparison: for sharp vision at one distance (monofocal plus), the surcharge for cataract is CHF 700 per eye. Toric trifocal lenses cost no more. All prices at a glance: Lens implantation costs · all lens options: Lens surgery in Zurich.

What are the risks of a trifocal lens, and how frequent are they?

ICL bei Alterssichtigkeit
  • Halos and glare: halos around 3.6 times and glare around 1.4 times more frequent than with monofocal lenses (de Silva 2016); they usually decrease with adaptation.
  • Contrast at dusk: slightly lower than with monofocal lenses (Schallhorn 2021).
  • After-cataract: 5.8 to 19.3 % of eyes need a YAG treatment within five years (Ursell 2020); it takes a few minutes.
  • Lens removed again: 0.83 % of 1’438 multifocal lenses, 0.28 % because of optical complaints (Kermani and Gerten 2016).
  • Infection: 0.023 % (Friling 2024).
  • Retinal detachment: 0.99 % over four years after lens surgery, markedly higher in high myopia (Daien 2015).

Frequently asked questions about trifocal lenses

Am I suitable for trifocal lenses?

 

Suitable candidates are usually people with presbyopia (with long-sightedness from about 45, otherwise from about 55 years of age) and stable, healthy eyes. During the suitability check we examine the structure of the eye (including the cornea, macula and tear film) and what you want to see in daily life. This determines which lens suits you: trifocal, EDOF, toric or another.

How quickly will I see after the surgery?

Many patients experience clear, significant improvements in their vision at various distances as early as the following day. In the first few weeks after the procedure, neuroadaptation optimizes the interplay of contrast, depth of field, and potential night vision. Full visual stability is typically achieved after a few weeks.

Does the Procedure Hurt?

The procedure itself is largely painless, as anesthesia is administered exclusively via special eye drops. Brief, slight pressure or touch sensations are possible during the short procedure, but we do not expect any significant pain. The entire standardized process is closely monitored by our team.

Are halos/glare normal?

Yes, the occurrence of halos or glare is normal at first, especially at night, and is a result of the optical lens design. These phenomena usually decrease significantly over time through neuroadaptation. We discuss this phenomenon in detail beforehand, select the lens design to suit your individual vision profile, and closely monitor the entire adjustment phase.

Am I allowed to drive after the surgery?

You may drive again as soon as medical clearance is given after the follow-up check and you feel absolutely safe in traffic. In most cases, this is possible within a few days, although night driving is only recommended after vision has fully stabilized.

Sports, swimming, sauna – from when?

Walks are often possible again after just a few days, light sport without body contact after about one to two weeks. Swimming and saunas are generally allowed after about 2 weeks, or once your doctor has given the all-clear, to avoid infections. Contact and ball sports are usually possible after four weeks, in each case once cleared at your check-up.

How long does a trifocal lens last?

Like any artificial lens, trifocal lenses are made to stay in the eye permanently and are usually not replaced. Because your own lens has been removed, a cataract can no longer develop. Clouding of the lens capsule may occur later (after-cataract), which the EyeLaser Zurich team treats in a few minutes with the YAG laser.

Will I still need glasses later?

The goal is extensive freedom from glasses in everyday life at all distances (near, intermediate, far). For very demanding specialized tasks, such as reading extremely fine print in low light, a light reading aid may nevertheless be useful. We discuss your expectations and realistic scenarios before the procedure.

Which lenses do you use?

We only use lenses from manufacturers that have been working in eye surgery for many years, for trifocal and multifocal lenses for example TECNIS Odyssey (Johnson & Johnson), enVista Envy (Bausch + Lomb) and PanOptix Pro (Alcon). If you also have astigmatism, we choose toric versions of the lenses. The final choice depends on a precise measurement of your biometry and a weighing of your priorities (e.g. best near vision vs. maximum comfort at night).

How much does a trifocal lens cost in Zurich?

For a refractive lens exchange, the trifocal lens at EyeLaser Zurich costs CHF 5’000 per eye, whether toric or not; with femtosecond laser CHF 6’000. Included are the procedure, the lens, a protective shield, the follow-up checks during the first three months and any laser fine-tuning in the first year. For cataract with basic insurance, you pay a surcharge of CHF 2’700 per eye. Six monthly instalments are interest-free.

Will my insurance cover the costs?

It depends on your situation, not on the lens. With a medically indicated cataract and basic insurance, the operation is billed under the TARDOC tariff; you pay the surcharge for the lens — CHF 2,700 per eye for EDOF and multifocal lenses, plus CHF 1,000 with the femtosecond laser. Refractive lens exchange without cataract costs CHF 5,000 per eye, CHF 6,000 with the femtosecond laser, regardless of the implant. Without Swiss basic insurance, lens-exchange prices apply to cataract surgery as well.

How is the follow-up care organized?

After a refractive lens exchange, EyeLaser Zurich checks your eyes the next day, after one week, after one month and after three months at Strehlgasse 33; these appointments are included in the price. After that, we recommend an annual check-up for CHF 180. In the first 24 hours you can reach the surgeon around the clock; after that, at night, the emergency department of the hospital on duty.

What happens if a small residual correction remains?

Should small residual values remain after the operation, these can – depending on the condition of the cornea and the overall findings – be fine-tuned (e.g., by means of a laser touch-up). Our treatment planning is fundamentally conservative and always prioritizes the long-term safety and stability of the eye.

Trifocal or EDOF: which is right for me?

In studies, trifocal lenses give better near vision without glasses, for example on a smartphone (Tavassoli 2024). EDOF lenses cover distance and screen; reading glasses are needed more often for small print. For halos, a meta-analysis found no established difference (Karam 2023). At EyeLaser Zurich, both cost CHF 5’000 per eye for a refractive lens exchange; we choose according to your daily life.

How Do I Make an Appointment?

Online or on 044 221 95 02. For a refractive lens exchange at EyeLaser Zurich, it starts with the free initial consultation, in person or by video; this is followed by the pre-examination for CHF 300, which is credited if you go ahead with treatment. For cataract, you book an examination directly, billed to basic insurance.

Who is not suitable for a trifocal lens?

At EyeLaser Zurich we generally advise against trifocal lenses in cases of disease of the macula or retina, an irregular cornea, untreated dry eyes, a large angle kappa or pronounced amblyopia (lazy eye) in one eye. If you drive a lot at night for work, EDOF or monofocal plus is often the better choice. Young, highly myopic people without presbyopia are usually candidates for the ICL.
