Trabeculotomy in Turkey: what it is and how it works
Trabeculotomy is a glaucoma operation that lowers eye pressure by opening the eye's own drainage pathway. Fluid (aqueous humour) normally leaves the eye through a sieve-like tissue called the trabecular meshwork and then enters Schlemm's canal. In some forms of glaucoma, especially glaucoma present from birth or early childhood, this meshwork is poorly formed or blocked, so pressure builds up and can damage the optic nerve. In trabeculotomy the surgeon cuts or opens the meshwork so that fluid can drain into the canal again. It is done in hospitals in Turkey, mostly by paediatric and glaucoma specialists, on one eye at a time.
This guide explains how trabeculotomy works, what the evidence says, when it is chosen instead of other glaucoma operations, what it costs compared with the UK, US and Germany, and what recovery and risks to expect. For the wider picture see our eye treatments in Turkey and the overview of glaucoma treatment.
When is trabeculotomy used instead of other glaucoma surgery?
Trabeculotomy is the classic first operation for primary congenital glaucoma, where a baby or young child has cloudy, enlarged corneas, light sensitivity and watering eyes. In that group the problem is a structural fault in the drainage angle, so repairing that angle makes sense. It is also used in some juvenile and adult open-angle glaucomas, sometimes combined with trabeculectomy (a different operation that creates a new drainage route under the eyelid). Modern versions of the idea, where the surgeon opens the meshwork from inside the eye, are sometimes grouped with minimally invasive glaucoma surgery.
It is not the usual choice for every glaucoma. If the angle is closed, if scarring is extensive or if pressure is very high and the optic nerve is badly damaged, a surgeon may prefer another route. That decision belongs at the consultation, after the eye has been examined in detail.
How is trabeculotomy performed, step by step?
The operation is done under general anaesthesia in children and often in adults too, because the eye must be completely still; some adults have local anaesthesia with sedation. A typical external (ab externo) technique follows these steps:
- A small flap of the outer eye wall (sclera) is lifted to find Schlemm's canal.
- A thin probe, or a fine flexible catheter, is passed into the canal.
- The probe is rotated, or the catheter is advanced round the canal, so that the inner wall and meshwork are opened into the front chamber.
- The flap and the surface of the eye are closed with fine stitches, and antibiotic and steroid are applied.
Surgery on one eye takes roughly 30 to 60 minutes. Some surgeons treat a large part of the canal in one go with a catheter; others treat a smaller arc with a probe. When both eyes are affected, the second is often operated on separately so that the surgeon can see how the first eye responds.
Does trabeculotomy work? What the evidence says
For primary congenital glaucoma, trabeculotomy and its close relative goniotomy are well established first-line operations, and many children reach a safe pressure with one or two operations. For adults the evidence is more mixed. Trabeculotomy usually lowers pressure by a moderate amount, which can be enough in early or moderate glaucoma but is generally less than what a trabeculectomy can achieve. Success also depends on age at diagnosis, how healthy the drainage angle is and how well drops and follow-up are continued afterwards.
Two honest points apply. Surgery does not reverse damage that has already happened; its aim is to protect the vision that remains. And a good first result does not remove the need for regular pressure checks, because pressure can rise again. A trustworthy hospital will describe success as controlling pressure, not as a cure.
Trabeculotomy cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges per eye, not hospital quotes. They depend on the surgeon's technique, whether the patient is a child (extra anaesthetic and monitoring time), the hospital stay and what the package includes. Each hospital confirms its own price in a written quote.
| Country | Approximate cost range (per eye) |
|---|---|
| Turkey | €1,500 – €4,500 |
| United Kingdom | €3,500 – €8,000 |
| United States | €6,000 – €18,000 |
| Germany | €3,000 – €7,500 |
What changes the price: anaesthesia type, one eye or both, a combined operation (for example with trabeculectomy or cataract surgery), the number of nights in hospital and the follow-up checks included. A package normally covers the pre-operative eye examination, the operation, anaesthetist, one or more nights, medication and transfers; ask for the list in writing and check what happens if a second operation is needed.
Trabeculotomy, trabeculectomy or laser: how do they compare?
All three aim to lower pressure; they differ in how invasive they are and how much pressure they remove. Trabeculectomy builds a new drainage channel and a small blister (bleb) under the upper eyelid. Laser trabeculoplasty treats the meshwork with a laser spot pattern without any cut; see laser trabeculoplasty. Broader options are outlined in our guide to glaucoma surgery.
| Option | Best suited to | Typical limits |
|---|---|---|
| Trabeculotomy | Congenital and some early-onset or open-angle glaucoma | Moderate pressure fall; less effective if the angle is closed or scarred |
| Trabeculectomy | Advanced adult glaucoma needing a low target pressure | Bleb care and more frequent follow-up; higher risk of low pressure and infection |
| Laser trabeculoplasty | Adults with open-angle glaucoma who want no incision | Effect may fade over time; not used for congenital glaucoma |
Who is a good candidate for trabeculotomy, and who is not?
Good candidates are children with congenital or early-onset glaucoma and some younger adults whose angle is open but poorly draining. Your surgeon will look at the pressure, the angle with a special lens (gonioscopy), the thickness and clarity of the cornea and the optic nerve. You are less suited if the angle is closed, if scar tissue blocks the canal, if a previous operation has failed in the same area or if the eye already has very little useful vision. Associated eye or general conditions that need treatment first are also reviewed before surgery is agreed.
Your trip to Turkey and trabeculotomy recovery
Most patients stay in Turkey about 7 to 10 days so that the surgeon can check the eye in the first week. The first day the eye is covered; after that, antibiotic and steroid drops are used several times a day for weeks, and pressure-lowering drops may be reduced or stopped according to the readings. Redness, light sensitivity and mild discomfort are common for a few days. Children need an adult to stop them rubbing the eye and may wear a protective shield. Avoid swimming, dust and contact sports for the period your surgeon sets, usually several weeks. Vision can be blurred for a while because of blood or swelling in the front of the eye and clears gradually. Flying is usually allowed once the surgeon has checked the eye. Follow-up pressure checks continue at home, often for years.
What are the risks and complications of trabeculotomy?
Every eye operation carries risks. The commonest effect is a small amount of bleeding into the front of the eye (hyphaema), which usually clears in days. Other possible problems include a temporary rise in pressure, inflammation, a shallow front chamber, infection, cataract developing later and failure to control pressure, which may mean a second operation. Rarely, bleeding or infection can threaten vision. The UK's Royal College of Ophthalmologists, the NHS and the American Academy of Ophthalmology all describe glaucoma surgery as a decision made case by case, balancing the risk of surgery against the risk of losing sight. Ask what the clinic will do if pressure rises after you leave Turkey and who will see you at home.
How do I choose a hospital for trabeculotomy, and what are the red flags?
Look for an ophthalmologist who regularly treats glaucoma, and for children a paediatric ophthalmologist and a paediatric anaesthetist; a hospital with an operating microscope, an anaesthetic team and an intensive-care facility; and a written plan and price before any deposit. Red flags include promises of a cure, quotes without a breakdown, pressure to book quickly, no named surgeon and no plan for follow-up.

What should I ask the clinic about trabeculotomy?
- Which technique will be used (probe, catheter or an internal approach) and why?
- What target pressure is planned, and what happens if it is not reached?
- Is it combined with another operation, and is that included in the price?
- How many glaucoma operations does the surgeon perform each year?
- Who will check the eye in the first week, and how are drops adjusted after I go home?
- Can reports and scans be sent to my own eye doctor?

Frequently asked questions
Trabeculotomy is a glaucoma operation that opens the trabecular meshwork, the eye's natural drainage filter, so fluid can flow into Schlemm's canal and eye pressure falls. It is the classic operation for congenital glaucoma in children.
For congenital glaucoma it is a well-established first-line operation and often controls pressure. In adults it usually lowers pressure moderately, which may be enough in early disease. It protects remaining vision but does not restore sight already lost.
Approximate ranges are €1,500 to €4,500 per eye in Turkey, against about €3,500 to €8,000 in the UK. The price depends on the technique, anaesthesia, hospital stay and follow-up; the hospital confirms it in a written quote.
Trabeculotomy opens the existing drainage pathway; trabeculectomy creates a new drainage route under the upper eyelid. The second usually lowers pressure further but needs more aftercare and carries more risk of low pressure and infection.
The eye is usually comfortable within a few days, although drops are used for several weeks. Blurred vision from blood or swelling clears gradually. Many adults resume light activity within one to two weeks, as the surgeon allows.
The operation is done under anaesthesia, so you feel no pain during it. Afterwards the eye may be sore, red and sensitive to light for a few days, usually eased by simple painkillers and prescribed drops.
It is routinely used in children with congenital glaucoma and is considered a standard operation. As with any surgery it carries risks such as bleeding, infection and the need for repeat operations, and it needs a paediatric anaesthetic team.
Some patients can reduce or stop drops, others still need one or more. The surgeon decides from your pressure readings, and regular checks continue because pressure can rise again over time.
Usually each eye is operated on separately so the surgeon can see how the first responds and reduce risk. Your surgeon will advise on timing, which may be in the same trip or at a later date.
Plan about 7 to 10 days so the surgeon can check the eye and pressure in the first week and adjust the drops before you fly home.
