In brief

EDOF lenses: range of focus, night vision and costs

The EDOF lens (extended depth of focus) is an artificial lens that, instead of fixed focal points, creates a continuous range of focus from distance to the screen. At EyeLaser Zurich, a refractive lens exchange with an EDOF lens costs CHF 5’000 per eye; for cataract, the surcharge is CHF 2’700. Reading glasses are often needed for small print.

Instead of several fixed focal points as with trifocal lenses, EDOF lenses extend the range in which you see sharply, from distance to about arm’s length: screen, dashboard, the person you are talking to. In studies, reading glasses are needed for small print more often than with trifocal lenses (Tavassoli 2024). Halos are also possible with EDOF lenses; whether they are less frequent than with trifocal lenses depends on the lens model (Karam 2023; Hovanesian 2022). The criteria for EDOF lenses were defined by the American professional society AAO (MacRae 2017).

Who are EDOF Lenses Suitable for?

EDOF-Linsen

EDOF lenses are often a good fit if you …

  • work a lot on a laptop, PC or tablet,
  • drive, including at night, and value contrast,
  • want clear distance and intermediate vision for sport and daily life,
  • accept that light reading glasses may be useful for small print.

When is an EDOF lens not a good fit?

  • You also want to read small print entirely without glasses → a trifocal lens is more suitable
  • Disease of the macula or retina, irregular cornea, untreated dry eyes → further assessment, often monofocal plus
  • Myopia under about 55 with a clear lens → ICL or laser eye surgery is more suitable

During the pre-examination we check your cornea, macula, tear film, pupil and visual habits, and then choose between EDOF, trifocal and monofocal plus, in a toric version if you have astigmatism.

EDOF, trifocal or monofocal plus: what is the difference?

EDOF Trifocal Monofocal plus
Vision ranges Distance to intermediate (arm’s length) Near, intermediate, distance one distance, usually far
Reading without glasses small print often with reading glasses usually without glasses reading glasses needed
Study value, near uncorrected worse than J2: 30 % uncorrected worse than J2: 3 % –
Halos and glare more than monofocal; on average not significantly fewer than trifocal, depending on the model less frequent more than monofocal few
Contrast at dusk slightly lower than monofocal slightly lower than monofocal unchanged
Refractive lens exchange CHF 5’000 per eye CHF 5’000 per eye CHF 5’000 per eye
Cataract (surcharge) CHF 2’700 CHF 2’700 CHF 700

How well do you see with EDOF lenses, and what are the risks?

ICL-Linsenimplantation
  • Independence from glasses: multifocal and EDOF lenses make glasses necessary less often than monofocal lenses; for near vision, trifocal lenses are better (Schallhorn 2021; Tavassoli 2024).
  • Halos and contrast: more frequent than with monofocal lenses, contrast at dusk slightly lower (Schallhorn 2021); adaptation takes weeks to months (Rosa 2017).
  • After-cataract: 5.8 to 19.3 % of eyes need a YAG treatment lasting a few minutes within five years (Ursell 2020).
  • Infection: rare, 0.023 % in a Swedish registry study (Friling 2024).
  • Retina: after lens surgery, the risk of retinal detachment is 0.99 % over four years, and markedly higher in high myopia (Daien 2015).
  • Residual refractive error: laser fine-tuning included in the first year for a refractive lens exchange, and for cataract in the tier with several distances (CHF 2’700).

What does an EDOF lens cost?

Woman with a clipboard next to the German words “Which laser eye method?” and “Life without reading glasses”

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. All prices at a glance: Lens implantation costs · all lens options: Lens surgery in Zurich.

A Word from Dr. Derhartunian

Dr. Victor Derhartunian

“EDOF technology closes the gap between monofocal and trifocal lenses. If you prioritise quality of vision and comfort when driving at night and want to do without glasses in daily life – especially when working at the PC – EDOF is often a good choice.”

Frequently asked questions about EDOF lenses

Am I Suitable for EDOF?

Usually yes for presbyopia and a focus on intermediate distances (PC, Küche, Gespräch). We examine the cornea, macula, tear film, pupil, and visual goals. With Astigmatism can be corrected with toric EDOF lenses; for macular or corneal issues, we advise on alternatives.

 

Will I See Completely without Glasses with EDOF?

In everyday life häufig ja: PC, Autofahren, Einkauf, TV. Für Very small print at close range – especially in low light – some people use fine reading glasses. We discuss this openly.

EDOF or trifocal: which is right for me?

In studies, trifocal lenses give better near vision without glasses (Tavassoli 2024); EDOF lenses cover distance and screen, with reading glasses often needed for small print. For halos, a meta-analysis found no established difference (Karam 2023); some non-diffractive EDOF models perform better. At EyeLaser Zurich, both cost CHF 5’000 per eye for a refractive lens exchange; what matters is your daily life.

What does a EDOF lens cost — for cataract and for lens exchange?

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.

Does the Procedure Hurt?

Outpatient under topical anesthesia – Pain is not expected. Brief pressure/touch sensations are normal. The procedure is standardized and explained step by step.

Are halos and glare possible with EDOF lenses?

Yes. Halos and glare occur more frequently with EDOF lenses than with monofocal lenses (Schallhorn 2021). Compared with trifocal lenses, a meta-analysis of 22 studies found no statistically established difference (Karam 2023); with non-diffractive EDOF models, studies report fewer halos. At EyeLaser Zurich we choose the lens model according to your daily life and support your adaptation at the check-ups.

How is Vision on Screens?

A core strength of EDOF: the intermediate range (≈ 60–80 cm) is stable and comfortable. Viele berichten von natural, relaxed screen vision.

Can I Play Sports?

You can resume light sport without body contact about one to two weeks after a refractive lens exchange. Swimming and saunas are usually possible after about two weeks once your doctor has given the all-clear. Contact and ball sports are usually possible after four weeks, in each case once cleared at your check-up.

How Long Does an EDOF Lens Last?

For lifelong use ausgelegt. Da die natürliche Linse ersetzt ist, kann später no cataracts can develop later.

Do I need follow-up checks after an EDOF lens?

Yes. After a refractive lens exchange, EyeLaser Zurich checks your eyes the next day, after one week, after one month and after three months; these appointments are included in the price. After that, we recommend an annual check-up for CHF 180. If you have problems 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 if Residual Refractive Error Remains?

Depending on the cornea/overall situation, fine-tuning are possible (e.g. laser touch-up). We plan conservatively and prioritize safety.

Are there Toric EDOF Lenses?

Yes. Bei Hornhautverkrümmung stehen toric EDOF designs are available. Selection based on biometry, axis, and stability.

Which EDOF lenses do you use?

EyeLaser Zurich uses EDOF lenses from established manufacturers, for example PureSee or LuxSmart; which model suits your eye is decided by the measurements from the pre-examination and your daily life (near vision, night driving, screen). If you have astigmatism, we choose the toric version. For a refractive lens exchange, every lens costs the same, CHF 5’000 per eye.

Does Basic Insurance Cover 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 Do I Make an Appointment?

Online or on 044 221 95 02. For a refractive lens exchange, it starts with the free initial consultation at EyeLaser Zurich, 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; it is billed to basic insurance together with all associated examinations.
