EDOF stands for Extended Depth of Focus (erweiterte Tiefenschärfe). Statt mehrerer fixer Brennpunkte (Multifokal/Trifokal) erzeugen EDOF-Linsen einen continuous range of focus from distance to intermediate distance (≈ 60–90 cm).
Your advantage: a very natural visual impression, comfortable night vision and stable computer vision – ideal for everyday life, work, and mobility.
Note: like a modern autofocus that keeps not just one point, but an entire area in focus.
EDOF is particularly beneficial if you…
During the suitability assessment, we check the cornea, macula, tear film, pupil, and visual habits and individually select EDOF vs. alternatives (incl. toric variants for astigmatism).
| Criterion | EDOF | Trifocal | Monofocal |
| Near | good–very good (everyday, menus, labels); small print may require reading glasses | very strong (mostly full near vision independence) | Reading glasses needed |
| Intermediate (60–80 cm) | very strong (PC, kitchen, conversation) | very strong | medium |
| Distance | very good | very good | very good |
| Halos/Glare | generally fewer | possible initially, usually subside | minimal |
| Visual Impression | very natural, wide depth of focus | 3 defined distances | one distance |
| Spectacle Independence | high in everyday life; near small print may require glasses | very high at all distances | low |
Visual Profile (PC, Night Driving, Sports), Goals, Medical Conditions
Exact biometry & imaging quality → Decision EDOF vs. alternatives and toric yes/no
Topical Anesthesia, Micro-invasive Lens Exchange, Structured, Calm Process
Check-ups in Zurich; Rapid Return to Everyday Life/Work; Fine-tuning Possible (e.g., Laser Touch-up)
“EDOF technology closes the gap between monofocal and trifocal lenses. Those who prioritize visual quality and night driving comfort and want to avoid glasses in everyday life – especially when working on a PC – often make the best choice with EDOF.”
“Relaxed at the screen, clear in the distance – exactly what I was looking for.”
“Quiet at night, sharp everywhere during the day. For very small print, I use fine reading glasses – it doesn’t bother me.”
Tell your reading glasses Farewell. The first step is a simple, non-binding suitability analysis at our clinic in Zurich.
Find out whether you can see your life in focus again with your own eyes.
Yes, I would like a free suitability analysis!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.
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: broad depth of field, tends to have fewer halos, strong PC range, very natural impression.
Trifocal: maximum freedom from glasses inkl. Nah-Kleinstschrift; anfangs halos möglich, meist rückläufig. Decision based on visual habits & priorities.
Many experience results the following day klare Verbesserungen. In the following weeks, the visual system adapts (neuroadaptation); contrast & night vision stabilize.
Outpatient under topical anesthesia – Schmerzen erwarten wir nicht. Brief pressure or touch sensations are normal. The procedure is standardized and explained step by step.
Yes, possible – tends to be rarer/less frequent als bei klassischen Multifokal-Designs. Appropriate lens design, expectation management, and aftercare support the adjustment period.
A core strength of EDOF: the intermediate range (≈ 60–80 cm) is stable and comfortable. Viele berichten von natural, relaxed screen vision.
Light activity usually after a few days. Swimming/sauna typically after ≈ 2 weeks (ärztliche Freigabe). Contact/ball sports on an individual basis.
For lifelong use ausgelegt. Da die natürliche Linse ersetzt ist, kann später no cataracts can develop later.
Yes – structured plan (z. B. Tag 1, Woche X, Monat X) in Zürich. If you have any questions, you can reach us directly.
Depending on the cornea/overall situation, fine-tuning möglich (z. B. Laser-Touch-up). Wir planen konservativ und priorisieren safety.
Yes. Bei Hornhautverkrümmung stehen toric EDOF designs zur Verfügung. Selection based on biometry, axis, and stability.
We work with premium implants from leading manufacturers and select the design based on your visual profile (near, night comfort, screen).
With refractive motivation, usually no. With medical indication (z. B. Katarakt) erfolgt die Beurteilung gemäss gesetzlichen Vorgaben. We assist with the clarification process.
Online or by phone. Die Initial consultation is non-binding – we clarify suitability, goals, and the best lens option (EDOF, trifocal, monofocal, toric). Free initial consultation is possible.
