Glaucoma treatment in Turkey: what you should know first
Glaucoma is a group of eye diseases in which the optic nerve is slowly damaged, usually because the pressure inside the eye is too high for that nerve. Side vision is lost first and often unnoticed until the damage is advanced. Every proven treatment — drops, laser or glaucoma surgery — works the same way: by lowering the eye pressure, it slows or stops further damage.
Can glaucoma be cured? No. Vision that has already been lost does not come back, and NHS information is clear that treatment aims to prevent further loss. Any clinic that promises to restore sight lost to glaucoma or to "cure" it is not telling the truth. What treatment can do is keep the vision you have for the rest of your life — provided the pressure is controlled and checked regularly.
That shapes when travelling makes sense. Glaucoma treatment in Turkey is worth considering for a one-off procedure — SLT laser, laser iridotomy or an operation — when it is expensive or slow to get at home. It is not a reason to travel for eye drops or check-ups, which you need for life and should have near home. The hospitals that treat glaucoma are listed on this page with their prices.
Types of glaucoma and why the type matters
Open-angle glaucoma is the most common form: the eye's drainage channel works poorly and pressure rises slowly, without symptoms. Angle-closure glaucoma happens when the iris blocks the drainage angle; it can develop slowly or suddenly, with a painful red eye, blurred vision and nausea — an emergency that needs treatment within hours, not a trip abroad. Normal-tension glaucoma damages the nerve at normal pressures; ocular hypertension is raised pressure without damage yet. Secondary glaucoma follows another condition, and congenital glaucoma affects babies and children.
The type decides the treatment: SLT laser suits open-angle glaucoma and ocular hypertension, laser iridotomy suits a narrow or closed angle, and surgery is for pressure that remains too high. More about the condition: glaucoma.
Tests before glaucoma treatment in Turkey
No treatment should be decided without a full examination on the clinic's own equipment, even if you bring results from home. It usually includes eye pressure measurement (tonometry), corneal thickness (pachymetry, because a thick or thin cornea changes how pressure readings should be read), examination of the drainage angle with a special lens (gonioscopy), a visual field test, an OCT scan of the optic nerve and nerve fibre layer, and photographs of the optic disc. Together these confirm the type of glaucoma, how advanced it is and what pressure the eye needs.
The tests take a few hours and are done the day before any laser or surgery. Bring every previous field test and scan you have: glaucoma is judged by change over time, and earlier results let the specialist see whether your disease is stable or getting worse — which often decides whether laser or surgery is needed at all.
Glaucoma eye drops
Glaucoma eye drops are the most familiar treatment: prostaglandin analogues (such as latanoprost), beta-blockers (such as timolol), carbonic anhydrase inhibitors, alpha-agonists and newer drugs, often combined. They work well when used every day, but many people find daily drops hard to keep up, and some develop red, irritated eyes or other side effects. Drops are not a treatment to travel for: they are prescribed and adjusted by your eye doctor at home. Laser and surgery are alternatives or additions when drops are not enough, not tolerated or not used reliably.
SLT laser and other laser treatments
Selective laser trabeculoplasty (SLT laser) treats the drainage channel with low-energy laser pulses so fluid drains better. It takes a few minutes, is done with numbing drops in an outpatient room, and you walk out afterwards. The NICE guideline on glaucoma (NG81) recommends offering SLT as a first treatment for open-angle glaucoma and ocular hypertension. In the LiGHT trial, published in The Lancet in 2019, about three-quarters of patients treated first with SLT needed no drops three years later. The effect can wear off over years, and SLT can be repeated. See laser trabeculoplasty.
Laser iridotomy makes a tiny opening in the iris so fluid can bypass a blocked angle; it treats or prevents angle-closure glaucoma. See laser iridotomy. Cyclophotocoagulation uses laser on the structure that produces fluid; it is usually kept for advanced or hard-to-treat glaucoma.
Glaucoma surgery: trabeculectomy, tubes and MIGS
When drops and laser do not lower the pressure enough, an operation creates a new drainage route. The options, compared:
| Treatment | How it works | Typically used for | Stay in Turkey |
|---|---|---|---|
| SLT laser | Improves outflow through the natural drain | Open-angle glaucoma, ocular hypertension | 2–3 days |
| Laser iridotomy | Small opening in the iris | Narrow or closed angle | 2–3 days |
| MIGS (micro-stents and similar) | Tiny device or channel improves drainage, often with cataract surgery | Mild to moderate open-angle glaucoma | about 5–7 days |
| Trabeculectomy | New drainage channel under a flap in the white of the eye | Moderate to advanced glaucoma | about 10–14 days |
| Tube (drainage device) | Silicone tube drains fluid to a plate on the eye | Previous failed surgery, complex glaucoma | about 10–14 days |
Trabeculectomy is the long-established operation and lowers pressure strongly, but the first weeks need frequent checks and adjustments — stitches may be released, drops changed — which is why the stay is longer. MIGS (minimally invasive glaucoma surgery) is gentler and recovers faster but lowers pressure less, and is often combined with cataract surgery. See glaucoma surgery and trabeculotomy for the operations in detail.
Glaucoma treatment cost in Turkey compared
The figures below are approximate private prices per eye, confirmed in a written quote after your examination. They include the procedure, the surgeon and the checks during your stay, not lifelong follow-up.
| Treatment (per eye) | Turkey | United Kingdom (private) | United States | Germany |
|---|---|---|---|---|
| SLT laser | about €300–€700 | about £700–£1,500 | about $1,000–$2,000 | about €300–€800 self-pay |
| Laser iridotomy | about €200–€500 | about £500–£1,200 | about $800–$1,500 | about €200–€600 self-pay |
| MIGS with cataract surgery | about €2,000–€4,000 | about £3,500–£6,000 | about $5,000–$9,000 | about €2,500–€5,000 |
| Trabeculectomy or tube | about €1,500–€4,500 | about £3,000–£6,000 | about $4,000–$9,000 | about €2,500–€5,000 |
All figures approximate. The glaucoma treatment cost depends on the type of glaucoma, the device used in MIGS or tube surgery, whether both eyes are treated and how many checks are needed. In the UK, glaucoma treatment, including laser and surgery, is available free on the NHS; insured patients in the US and Germany are usually covered. Compare the total — flights, hotel and time away — with what you would pay at home.
When glaucoma treatment in Turkey makes sense — and when it does not
It can make sense when you are paying privately for SLT, iridotomy or an operation, when you want a second opinion on whether surgery is needed, or when the wait for a procedure at home is long. It does not make sense for an acute attack of angle-closure glaucoma (get emergency care where you are), for routine drops and monitoring, or when you cannot stay long enough for the post-operative checks.
Before you travel, send your recent results: eye pressure readings, visual field tests, OCT scans of the optic nerve and your current drops. The specialist can then say whether laser or surgery is likely, how long you need to stay, and what it will cost.
The trip, recovery and flying home
For SLT or iridotomy plan two to three days: examination and tests, the laser, and a pressure check about an hour later and again the next day. You can usually fly the following day. Pressure can rise briefly after laser, which is why the check matters.
After trabeculectomy or a tube, plan ten days to two weeks. The eye is checked several times in the first days and the surgeon may adjust stitches to fine-tune the pressure; vision may be blurred for a few weeks. Avoid heavy lifting, bending with the head down, rubbing the eye and swimming as advised. Ask the surgeon specifically when you may fly, especially if any gas or air was used in the eye. Keep your drops in hand luggage with the prescription.
Risks of SLT laser and glaucoma surgery
SLT is low-risk: temporary redness, mild discomfort, inflammation and a short pressure spike are the usual problems. Laser iridotomy can cause brief blurring, a pressure rise or, occasionally, a line or glare in vision. Glaucoma surgery carries more risk: pressure too low (hypotony) in the first weeks, bleeding, infection, cataract developing sooner, failure of the new drain through scarring, and the possible need for further surgery. A trabeculectomy leaves a small blister ("bleb") under the upper lid that carries a lifelong small risk of infection — any red, sticky or painful eye after this operation needs same-day care. Your surgeon should explain the risks for your eye and your type of surgery in writing.
Lifelong follow-up at home
Glaucoma treatment is never finished after one trip. You need pressure checks, visual fields and nerve scans for life, usually every few months at first and then once or twice a year, and the treatment is adjusted as needed. Arrange this before you travel: an NHS or private eye clinic, or an optometrist with glaucoma training, should agree to see you afterwards. Bring home a full written report — diagnosis, pressures before and after, what was done, drops and their schedule — so your doctor at home can take over.
Questions to ask the clinic: what pressure target do you aim for, what happens if pressure rises after I go home, how will you communicate with my doctor at home, and what does a second procedure cost?

Frequently asked questions
No. Treatment lowers eye pressure to slow or stop further damage to the optic nerve, but vision already lost cannot be restored. With good control and regular checks most people keep useful sight for life.
It can be for a one-off procedure such as SLT laser, laser iridotomy or surgery that is expensive or slow to get at home. It is not worth travelling for drops or routine check-ups, which you need for life near home.
Selective laser trabeculoplasty is a few-minute outpatient laser that improves drainage of fluid from the eye. NICE recommends it as a first treatment for open-angle glaucoma and ocular hypertension; its effect can fade over years and it can be repeated.
For many people, at least for some years. In the LiGHT trial about three-quarters of patients treated first with SLT needed no drops three years later. Some still need drops, and regular checks remain essential.
Approximately €300–€700 per eye for SLT laser, €200–€500 for laser iridotomy and €1,500–€4,500 for trabeculectomy or tube surgery, confirmed in a written quote after examination.
An operation that creates a new drainage channel under a small flap in the white of the eye, lowering pressure strongly. It needs frequent checks in the first weeks, so plan about ten days to two weeks in Turkey.
Minimally invasive glaucoma surgery uses tiny stents or channels to improve drainage, often at the same time as cataract surgery. It recovers faster than trabeculectomy but lowers pressure less.
Two to three days for SLT or iridotomy, about five to seven days for MIGS with cataract surgery, and about ten days to two weeks for trabeculectomy or tube surgery.
Yes. Diagnosis, drops, laser and surgery for glaucoma are available on the NHS; people diagnosed with glaucoma are also entitled to free NHS sight tests.
Usually the day after laser treatment. After surgery, ask the surgeon; flying is generally allowed once the pressure is stable, but not if gas has been placed in the eye.
Yes, for life. Pressure, visual fields and the optic nerve must be checked regularly at home, because glaucoma can progress even after successful treatment.
Sudden eye pain, a red eye, blurred vision, haloes around lights, headache, nausea or vomiting. This is an emergency: go to the nearest eye casualty or emergency department at once.
