What is pupilloplasty and how does it work?
Pupilloplasty is an eye operation that repairs or reshapes the pupil, the black opening in the centre of the iris. When the iris is torn, stretched, scarred or stuck to the lens, the pupil can become too large, off-centre, irregular or even closed. Light then enters the eye in the wrong way, which causes glare, halos, light sensitivity and sometimes double vision in one eye. In pupilloplasty the surgeon works inside the front of the eye, frees adhesions if there are any, and draws the iris tissue together with very fine stitches so that the pupil becomes smaller, rounder and better placed. Eye hospitals in Turkey perform it as a stand-alone repair or in the same session as cataract or lens surgery.
This guide explains which problems it treats, what the evidence says, what it costs compared with the UK, US and Germany, what recovery involves and how to check a hospital. For the wider range of operations see our eye treatments in Turkey.
Which pupil problems can pupilloplasty correct?
The operation is aimed at a damaged pupil, not at poor sight in general. The usual reasons are:
- Injury: a blunt blow can tear the iris sphincter muscle and leave a large, oval or "keyhole" pupil that no longer narrows in bright light (traumatic mydriasis).
- Previous eye surgery: an iris pulled toward a surgical wound, or a pupil left distorted after cataract or glaucoma surgery.
- Inflammation: long-standing uveitis can glue the iris edge to the lens (posterior synechiae) and distort or close the pupil.
- Congenital differences: displaced or irregular pupils present from birth, in selected cases.
- Iris defects: small tears or a partly missing iris edge, sometimes seen with a dislocated lens.
Doctors often use the same word for the repair of a pupil that has closed over, where a membrane is removed so light can pass again. If you have no pupil at all, or a pupil blocked by scar tissue, ask whether a new opening is needed; that is described in our guide to artificial pupil surgery.
Does pupilloplasty work? What the evidence says
The evidence base is mainly case series and surgeon reports rather than large randomised trials, because the condition is uncommon and every damaged eye is different. Within those reports, a smaller and rounder pupil reliably reduces glare, haloes and light sensitivity, and monocular double vision often improves when the stray light path is closed. What the operation cannot do is repair other damage: if the retina, optic nerve or cornea were injured at the same time, sharpness of sight depends on them, not on the pupil. Some people also notice a slightly reduced field of dim-light vision after the pupil is made smaller. A careful surgeon will examine the whole eye, explain what improvement is realistic and will not promise a return to your former vision.
Pupilloplasty cost in Turkey compared with the UK, US and Germany
The ranges below are approximate figures per eye, not hospital quotes. The price depends on how complex the repair is, whether it is combined with a lens or cataract operation, the type of anaesthesia and the number of nights in hospital. Each hospital confirms its own price in a written plan after reviewing your records.
| Country | Approximate cost range (per eye) |
|---|---|
| Turkey | €1,000 – €3,500 |
| United Kingdom | €2,500 – €7,000 |
| United States | €3,500 – €10,000 |
| Germany | €2,000 – €6,000 |
A package normally covers the eye examination and scans before surgery, the operation, the surgeon and anaesthetist, the hospital stay, post-operative drops, check-ups before you fly and airport transfers. Ask for the list in writing, and ask whether a lens implant or a second procedure is included or would be charged separately.
How is pupilloplasty performed step by step?
Before surgery the team measures your vision and eye pressure, examines the iris and lens under the microscope and often images the front of the eye, so the surgeon can see exactly how much tissue is damaged. On the day:
- Anaesthesia: adults usually have numbing drops or an injection around the eye, with light sedation; children and anxious patients may have general anaesthesia.
- Access: two or three tiny incisions are made at the edge of the cornea and the front chamber is filled with a protective gel.
- Freeing the iris: adhesions to the lens or cornea are gently released, and any scar membrane is removed.
- Suturing: the surgeon passes a very fine polypropylene thread through the iris edges and ties it, a single stitch or several, to narrow and centre the pupil. Sliding-knot and purse-string methods are common.
- Finishing: the gel is rinsed out, the incisions are checked and a protective shield is placed.
Surgery usually takes 30 to 60 minutes. If you also have a cloudy lens, the surgeon may replace it in the same sitting; see our guide to cataract and lens surgery.
Pupilloplasty or another way of managing a damaged pupil?
Surgery is not the only option. Some people manage well with tinted or iris-print contact lenses, tinted glasses or a hat and sunglasses; others need an implanted artificial iris. The table compares the main choices in general terms; the right one depends on how much iris is missing and the health of the rest of the eye.
| Option | Suited to | Typical limits |
|---|---|---|
| Pupilloplasty (sutures) | Torn, enlarged or distorted pupil with enough iris tissue to draw together | Needs surgery; limited if iris is very thin or largely missing |
| Artificial iris implant | Large iris defects or loss of most of the iris | Larger operation; used in specialist centres |
| Tinted or iris-print contact lens | Mild glare and cosmetic concern | Needs daily wear and good lens fit; may not suit an injured cornea |
| Tinted glasses and sunglasses | Sensitivity to bright light | Reduces symptoms only; does not change the pupil |
A related technique, laser iridotomy, makes a tiny hole in the iris to relieve pressure in some forms of glaucoma; it is a different operation with a different purpose.
Who is a good candidate for pupilloplasty, and who is not?
Good candidates have a stable eye, a pupil that is clearly irregular or enlarged, troublesome glare or double vision, and enough healthy iris tissue to repair. Surgery is usually delayed while the eye is still inflamed, and in injured eyes surgeons often wait until the eye has settled. Less suitable situations include active infection, uncontrolled raised eye pressure, a retina or optic nerve so damaged that little sight could be gained, and very thin iris that would tear under the stitch. Tell the team about previous eye surgery, glaucoma, uveitis, diabetes and any blood-thinning tablets.
What results can you realistically expect?
The change is visible in a mirror as a smaller, rounder pupil, but the main benefit is functional. Many people report less glare in daylight and less trouble with headlights and haloes at night. Photographs of the eye help you see the cosmetic change, but they cannot show how comfortable the vision is. Results vary with the cause: a clean traumatic tear usually repairs well, while an eye scarred by long-term inflammation may respond less predictably. In some eyes a stitch loosens and the pupil enlarges again, and a second repair is then discussed. Ask the surgeon what improvement is likely in your own case, and what it would mean if the pupil needed a second operation.
How long is the stay in Turkey and what is recovery like?
Most overseas patients stay about four to six nights: arrival and tests, surgery, then check-ups on the first day, within the first week and before the flight. The eye is covered for the first day. You use antibiotic and anti-inflammatory drops for several weeks, sometimes with drops to keep the pupil from sticking. Mild discomfort, watering and light sensitivity are common in the first days. Avoid rubbing the eye, swimming, dusty places and strenuous exercise for about two to four weeks, or as the surgeon advises. Desk work often resumes within a week, and driving only after the surgeon confirms your vision meets the legal standard.
Short flights are normally allowed once the first check shows the eye is stable. Keep the post-operative plan, drop schedule and the surgeon's report, and arrange a local eye specialist to review you after you return home, because the stitches and eye pressure need monitoring over the following weeks.
What are the risks of pupilloplasty?
All eye surgery carries risk. Possible problems include inflammation, raised eye pressure, bleeding inside the eye (hyphaema), swelling of the cornea or of the central retina (macular oedema), a loosened or cut stitch, and the pupil widening again. Infection inside the eye (endophthalmitis) is rare but serious and needs urgent treatment, and a retinal detachment can occur after any intraocular surgery. The NHS and the Royal College of Ophthalmologists advise anyone with sudden pain, loss of vision, a growing curtain over sight or a red, sticky eye after surgery to seek an eye casualty immediately. Ask the clinic in advance how it handles complications and who will treat you at home.
How to choose an eye surgeon and hospital in Turkey, and red flags
Look for an ophthalmologist who regularly treats trauma or anterior-segment problems, an operating theatre with a surgical microscope and sterile standards of a licensed hospital, and a team that examines your records, previous scans and photographs before quoting. A good clinic explains alternatives, states the limits of the repair and gives you a written plan with a price. Red flags include a firm quote without any examination or records, promises of perfect vision, no named surgeon, pressure to pay a deposit quickly and no follow-up plan. Our page on how it works describes the process, and you can start through the free quote form.

Frequently asked questions
Pupilloplasty is an eye operation that repairs a torn, enlarged, off-centre or scarred pupil. The surgeon frees any adhesions and uses very fine stitches to draw the iris together, which makes the pupil smaller, rounder and better placed.
Reports from surgeons show that it reliably reduces glare, haloes and light sensitivity and can improve one-eye double vision. It cannot repair retinal, nerve or corneal damage, so overall sharpness depends on the rest of the eye.
Approximate ranges are €1,000 to €3,500 per eye in Turkey, against roughly €2,500 to €7,000 in the UK. The price depends on complexity, combined lens surgery and the hospital stay, and is confirmed in a written plan.
People with an enlarged or distorted pupil after injury, previous eye surgery or long-term inflammation who have glare, light sensitivity or double vision. The eye must be stable and have enough healthy iris tissue for the repair.
The eye is covered for a day and you use drops for several weeks. Desk work often resumes within a week; avoid rubbing, swimming and strenuous exercise for about two to four weeks unless your surgeon says otherwise.
Numbing drops or an injection are used, so the operation itself should not hurt. Mild aching, watering and light sensitivity are common for a few days afterwards and are usually eased with simple painkillers.
Occasionally a stitch loosens or the tissue tears, and the pupil widens again. A second repair is then discussed. Regular check-ups in the first weeks help the surgeon notice this early.
No. Pupilloplasty repairs an existing pupil by reshaping the iris. Artificial pupil surgery creates a new opening when the natural pupil is closed or absent. A specialist examination decides which is suitable.
It is established eye surgery, but risks exist: inflammation, raised eye pressure, bleeding, swelling of the cornea or retina and, rarely, infection. Choosing an experienced ophthalmologist and attending every check-up lowers the chance of problems.
Plan on about four to six nights. This covers tests, the operation and check-ups on the first day and within the first week, so the surgeon can confirm the eye is stable before you fly.
