Lens Replacement Surgery in Turkey: Lens Options, Results and Recovery

If you are considering lens replacement surgery in Turkey, you are probably weighing two questions: is the operation right for my eyes, and which lens should I choose? The operation is well established. Most of the planning goes into the lens, because it shapes how you will see, and how often you will need glasses, for the rest of your life.

Prof. Dr. Elif Betül Türkoğlu, Professor of Ophthalmology, performs cataract and lens replacement surgery in Antalya, including complex cases. This guide gives an overview of the lens options, realistic results, recovery and risks, with links to a detailed page on each topic.

What is lens replacement surgery?

The eye's natural lens sits behind the colored iris and fine-tunes focus. With age it stiffens, so close work becomes harder (presbyopia), and later it may turn cloudy (cataract). Lens replacement surgery removes the natural lens through a tiny incision and replaces it with an intraocular lens (IOL), a small, foldable artificial lens designed to stay in the eye for life.

The same operation serves two purposes:

• Cataract surgery replaces a clouded lens. There is no need to wait until a cataract is "ripe"; surgery can be considered once it affects daily life. See cataract surgery in Antalya.
• Refractive lens exchange (RLE), or clear lens exchange, replaces a lens that is still clear, to reduce dependence on glasses. See refractive lens exchange.

Once the natural lens has been removed, a cataract cannot grow back, although the capsule that holds the new lens can cloud over later and need a quick laser treatment.

Who is lens replacement surgery suitable for?

No single age or prescription decides it. Candidates include people whose cataract affects reading, driving, work or hobbies (the UK's National Institute for Health and Care Excellence, NICE, advises against restricting surgery on the basis of a letter-chart score alone) and people from their mid-40s who want to depend less on glasses. A 2022 expert review suggests discussing RLE from about age 43, notes that prime candidates are usually over 50, and highlights farsighted (hyperopic) prescriptions of about +3 to +4 diopters or more.

Lens replacement is usually not the first choice for younger nearsighted (myopic) adults. They would lose their remaining natural focusing ability, and long, nearsighted eyes carry a higher risk of retinal detachment after lens surgery. The alternatives are compared in RLE vs LASIK.

What types of intraocular lens are there?

Lenses differ mainly in how they share light between distances. The more distances a lens covers, the less you need glasses, but the more likely you are to notice halos around lights at night. European guidance (ESCRS, 2024) recommends matching the lens to the health of the eye, to how strongly you want to be free of glasses and to realistic expectations. It notes that EDOF lenses and monovision give good intermediate vision with significantly fewer visual disturbances than multifocal lenses.

What do "smart lens" and "premium IOL" mean?

In Turkey, "smart lens surgery" (akıllı lens) is a popular term rather than a medical category. It usually means a presbyopia-correcting lens, such as a trifocal or other multifocal lens implant or an EDOF lens, sometimes with astigmatism correction. "Premium IOL" covers any lens beyond the standard monofocal. In the UK's National Health Service, for example, the standard lens is monofocal and multifocal lenses are not offered; they are available privately.

Each lens family has its own guide: EDOF lenses, trifocal lenses and toric lenses for astigmatism. To compare them by lifestyle and eye health, see how to choose a lens.

What results can you realistically expect?

When the rest of the eye is healthy, lens replacement usually gives clear vision. What differs between lenses is how often you still use glasses, and how lights look at night.

How likely are you to be free of glasses?

• Monofocal lenses: most people need reading glasses. In the US approval trial of a trifocal lens, 0.9% of the monofocal comparison group could read at 40 cm (16 inches) at about the 20/20 level without glasses, against 49.6% of the trifocal group.
• Multifocal lenses in general: a Cochrane review of 20 trials found that people with multifocal lenses were about a third less likely to depend on glasses than those with monofocal lenses.
• Trifocal lenses: a manufacturer-funded analysis of 13 studies of one widely used trifocal lens found complete spectacle independence in 91.6% of patients.

Halos, glare and night driving

Lenses that split light create faint rings (halos) or starbursts around lights in the dark. In the Cochrane review, halos were about 3.6 times and glare about 1.4 times as common with multifocal lenses. Being badly troubled is much less common: in the trifocal approval trial, 2.4% of patients were bothered "very much" by halos, against 0.9% with a monofocal lens. If you drive a lot at night, weigh this trade-off carefully.

Your brain needs time to adapt

With a multifocal lens, the brain learns to favor the sharp image and ignore the blurred ones (neuroadaptation). In a brain-imaging study, visual-disturbance scores fell from 2.82 one week after multifocal lens implantation to 1.14 at six months, similar to patients with monofocal lenses. Halos usually fade over weeks to months but may not disappear completely.

Are you a good candidate for a premium lens?

Presbyopia-correcting lenses work as designed only in an otherwise healthy eye. The planning examination looks in particular at:

• the retina and macula: multifocal lenses are considered unsuitable in retinitis pigmentosa and Stargardt disease, and other macular conditions call for caution;
• the optic nerve: glaucoma makes surgeons cautious with multifocal designs;
• the cornea: irregular astigmatism (for example from keratoconus or scarring) limits multifocal lenses, and after LASIK, PRK or RK special calculation methods are needed;
• the pupil and lens supports: a multifocal lens that sits off-center by as little as 0.75–1.00 mm loses optical quality, which matters with small pupils or weak lens fibers (zonules);
• the tear film: ESCRS recommends diagnosing and treating dry eye before surgery;
• your expectations: what you want, and what you are willing to trade for it.

Which tests are done before surgery?

European guidance lists refraction, visual acuity, a slit-lamp examination, eye pressure and biometry as essentials, adding corneal mapping when astigmatism is present and an OCT scan of the retina when indicated. Before a premium lens, planning typically includes optical biometry (a light-based scan of eye length and corneal curvature, recommended by NICE), corneal topography or tomography, an OCT scan of the macula, tear-film tests and a dilated examination of the retina and optic nerve.

What happens on the day of surgery?

1. Preparation. Drops widen the pupil and numb the eye. Most people stay awake; sedation or general anesthesia can be arranged for special needs.
2. Removing the natural lens. Through a tiny, self-sealing incision at the edge of the cornea, the lens is broken up with ultrasound (phacoemulsification) and removed, leaving its thin capsule in place.
3. Implanting the new lens. The folded IOL is injected into the capsule, where it unfolds; a toric lens is rotated to its planned angle.
4. Preventing infection. An antibiotic is placed inside the eye at the end, a step European guidance supports with its highest grade of evidence.
5. Going home. The operation usually takes about 20–45 minutes, and you go home the same day with a protective shield and a schedule of drops.

Both eyes on the same day? For suitable, low-risk eyes, European guidance considers same-day surgery on both eyes effective and safe. With premium lenses there is a trade-off: operating on separate days allows the first eye's result to refine the calculation for the second lens. Laser-assisted surgery is another way of performing some steps and is explained separately.

How long is recovery, and when can you fly home?

Vision usually improves over the first few days. Most people return to light activities within two to three days, full recovery takes about four to six weeks, and any new glasses are usually prescribed about six weeks after the second eye. The American Academy of Ophthalmology considers flying soon after uncomplicated surgery to carry no risk, but it is sensible to fly only after a post-operative check. Early check-ups can be spread over up to two weeks in uncomplicated cases, so later visits can take place with an eye doctor at home.

How long you stay for lens replacement in Antalya depends on whether one or both eyes are treated and on the lens: a light-adjustable lens, for example, needs visits over several weeks. See recovery and flying home and our guide for international patients. Airport transfers, accommodation, interpreters and scheduling can be organized through BergemHealth, the practice's international patient coordination partner.

What are the risks of lens replacement surgery?

UK patient guidance from the Royal College of Ophthalmologists and RNIB puts the risk of a serious complication at about 1 in 1,000. The main issues to know about are:

• Clouding of the capsule behind the lens (posterior capsule opacification, or "secondary cataract") affects about 1 in 3 people within five years and is treated with a quick YAG laser procedure.
• Retinal detachment is more likely in long, nearsighted eyes. In a Swedish register of 58,624 eyes, it occurred in 0.51% over an average of 4.7 years overall, but in 9.5% of men under 60 whose eyes were longer than 25 mm.
• Inflammation, swelling of the central retina (macular edema), raised eye pressure or an unexpected lens power are usually treatable; infection inside the eye (endophthalmitis) is rare but serious.

Details are on risks and side effects of lens replacement.

How much does lens replacement surgery cost?

The price mainly reflects the lens type (trifocal and toric lenses cost more than a standard monofocal), whether one or both eyes are treated, the planning tests and the after-care included. When comparing quotes, check that the lens model, tests, follow-up and the policy for enhancements or YAG laser are listed in writing. See lens replacement cost for published price comparisons; the practice can prepare a personalized quote once your eye details are known.

What is new in lens replacement (2024–2026)?

As of September 2026, notable developments include:

• European guidance: the European Society of Cataract & Refractive Surgeons (ESCRS) published its first cataract surgery guideline in 2024.
• New trifocal and "full range" lenses: TECNIS Odyssey began its US rollout in September 2024. Clareon PanOptix Pro, introduced in 2025, is reported by its manufacturer to use 94% of incoming light, against 88% for its predecessor. US Food and Drug Administration (FDA) approval of the hydrophobic FineVision HP trifocal was announced in October 2025.
• Refractive EDOF lenses: TECNIS PureSee, described by its manufacturer as a purely refractive EDOF lens, gained FDA approval in March 2026 after use in nearly half a million eyes worldwide, according to the company.
• Low-halo designs: enhanced monofocal and non-diffractive EDOF lenses aim to extend the range of vision while keeping night-time halos close to monofocal levels.

US approval often follows earlier availability elsewhere. Lens names on this site are market examples and do not indicate which lenses are used at this practice.

Choosing where to have lens replacement surgery in Turkey

Wherever you have surgery, a few questions help you judge a clinic:

• Who will examine you and operate, and will you meet them before the day of surgery?
• Will your whole eye, including the retina, be examined before a lens is recommended?
• Does the written quote name the lens model and list the tests, follow-up visits and enhancement policy?
• What happens if you need care after you return home?
• Have you discussed your plans with your own doctor? UK travel advice recommends doing so before booking treatment abroad.

Prof. Türkoğlu performs cataract and lens replacement surgery alongside her work as an ocular oncologist and is a member of the European Society of Cataract & Refractive Surgeons. She examines your eyes, explains which lens types suit them and which do not, and plans the operation with you, in English or Turkish. Patients who have had an eye tumor treated, or who have other conditions that make surgery more demanding, can have both aspects assessed together; see complex cataract surgery.
