The ZEISS AT LARA is an extended depth of focus (EDOF) intraocular lens used in cataract surgery and refractive lens exchange. At our partner clinics, surgery with the AT LARA starts from £3,600 per eye, all-inclusive of consultation, biometry, theatre, the EDOF lens, post-op drops and follow-ups. A toric version for astigmatism is available from £3,900 per eye. EDOF sits between a monofocal and a trifocal lens — it gives stronger spectacle independence than a monofocal with fewer night-time haloes than a trifocal, ideal for patients who want excellent distance and intermediate vision and are happy to use light reading glasses for very fine print.
What is the ZEISS AT LARA EDOF lens?
The ZEISS AT LARA (for example the AT LARA 829MP) is a preloaded hydrophilic acrylic intraocular lens with an extended depth of focus optic. Rather than creating two or three fixed focal points like a multifocal lens, an EDOF design elongates a single, continuous zone of clear vision. In practice that means crisp distance vision flowing smoothly into intermediate range — the dashboard, the kitchen worktop, the computer screen — with usable near vision for everyday tasks.
Because the optic stretches one focal range instead of splitting light across several, EDOF lenses such as the AT LARA typically produce fewer of the rings, haloes and starbursts around lights that some patients notice with full trifocal lenses. That tends to make them a comfortable choice for people who drive at night. A toric version (AT LARA toric) is available to correct astigmatism at the same time as the cataract.
Who suits an EDOF lens like AT LARA?
- You want strong distance and intermediate vision — driving, screens, cooking, shopping
- You value night-driving quality — fewer haloes and glare than a trifocal
- You're happy to keep light reading glasses for very small or fine print
- You have astigmatism — the toric AT LARA can correct it in the same procedure
- You prefer a natural, smooth range of vision over maximum spectacle independence
Not sure which lens is right for you? Your consultant recommends an IOL based on your eye anatomy, astigmatism and lifestyle — the choice is permanent, so it's worth getting right.
Book a lens consultationHow AT LARA EDOF compares to monofocal & trifocal
Choosing an intraocular lens is the most important decision in cataract surgery, because the lens is permanent. The AT LARA sits in the middle of the spectrum: more spectacle freedom than a monofocal, fewer night-time haloes than a trifocal. Here's how the three families compare.
The toric AT LARA (which also corrects astigmatism) is available from £3,900 per eye. If your priority is the absolute most reading vision without glasses, your surgeon may discuss a trifocal IOL instead; if you want to see how AT LARA compares with other EDOF designs, see our pages on the Clareon Vivity, Tecnis PureSee and Rayner Galaxy EDOF lenses, or our general EDOF lens cost guide.
The procedure
The AT LARA is implanted during standard cataract surgery or refractive lens exchange (RLE). It is a day-case operation under local anaesthetic eye drops — you stay awake and feel no pain, only mild pressure and light. The procedure takes 15 to 25 minutes per eye, and you'll be at the clinic for around 2 to 3 hours including pre-op checks and post-op rest.
- Numbing drops are placed in your eye, and the surrounding skin is cleaned with sterile solution.
- The surgeon makes a tiny 2.2–2.8mm incision at the edge of your cornea — small enough to seal itself afterwards without stitches.
- Phacoemulsification is used: a fine ultrasound probe gently breaks up the clouded natural lens and removes the fragments.
- The preloaded ZEISS AT LARA EDOF IOL is folded and placed into the capsular bag through the same incision, where it unfolds and centres.
- The eye is shielded and you rest for 30–60 minutes before going home.
Recovery week-by-week
Recovery after AT LARA implantation is the same as routine cataract surgery. Most patients notice clearer vision within days, and the eye settles by around four weeks. The brain also adapts to the extended range of focus over the first weeks. Here's what to expect:
Day of surgery
Vision is hazy for a few hours. Eye shield worn for the first night. No driving, no heavy lifting. Eye drops begin.
Days 1–3
Vision begins to clear noticeably. Mild grittiness or watering is normal. Most return to gentle activities and screens.
Week 1
First post-op review. Most patients are back to driving, working and walking — no swimming or eye rubbing yet.
Weeks 2–4
Vision continues to refine and the brain adapts to the EDOF range. Eye drops continue. New glasses (if any) at week 4–6.
Beyond a month
Final vision is settled with a smooth distance-to-intermediate range. Second eye scheduled if both are being treated.
