Is it worth going abroad?
Private glaucoma surgery such as trabeculectomy in the UK commonly costs about £3,000 to £5,000 per eye, with around £3,500 a typical figure. In the United States the cost without insurance is often around $4,200 to $5,000 or more. Abroad, in markets such as Turkey, prices are frequently quoted from about $1,680 to $2,700 per eye. The honest point worth making first is that glaucoma threatens sight, so it is treated on the NHS, and the aim of surgery is to preserve the vision you have rather than to improve it.
Costs below are indicative ranges, reviewed April 2025, and vary by your circumstances, the technique used, and what a package includes. They are not a quote and not a promise of a result.
The procedure, in plain terms.
Glaucoma is a group of conditions in which the optic nerve is damaged, usually linked to raised pressure inside the eye. Surgery aims to lower that pressure and slow further loss of sight. The traditional operation, trabeculectomy, creates a small drainage channel under the eyelid so fluid can leave the eye, forming a small blister called a bleb. Newer options include drainage tube implants and a family of lower risk keyhole procedures known as minimally invasive glaucoma surgery, often combined with cataract surgery. Laser treatments such as selective laser trabeculoplasty are a separate, less invasive step. The right choice depends on the type and severity of your glaucoma.
Who it tends to suit. People whose glaucoma is progressing despite eye drops or laser, those who cannot tolerate or use their drops reliably, and people whose pressure stays too high. The decision rests on the state of the optic nerve and field of vision, not on cost.
Who it tends not to suit. People whose pressure is well controlled on drops, who may not need surgery yet, and those with very advanced loss where the benefit is limited. Any eye surgery carries risk, so a careful specialist assessment comes first.
The price, honestly.
The type of surgery is the main price driver. A trabeculectomy or tube implant costs more than a keyhole minimally invasive procedure. Abroad, lower running costs can reduce the price, but the surgeon judgement and the long term monitoring matter far more than the saving.
Indicative ranges, reviewed April 2025, mixing currencies because that is how clinics quote them. Not a quote. Glaucoma needs lifelong follow up, so a low headline price that leaves out monitoring is not the full cost.
US pricing without insurance is typically higher again, often around $4,200 to $5,000 or more per eye. Ask which technique is quoted, what follow up is included, and the currency you are billed in. For a fuller breakdown see our cost by country guide.
What can go wrong.
Glaucoma surgery is generally safe, but it is surgery on the eye, and the aim is to protect sight rather than improve it. Complications, though uncommon, can affect vision and sometimes need further treatment.
Drainage can scar over time. Around a third of trabeculectomies need further intervention within a few years, and many initially successful blebs scar within three to five years, so monitoring is lifelong.
If fluid drains too fast the pressure can fall too far, a state called hypotony, which can blur vision and, if it persists, harm the eye. It is more common when scar slowing medicines are used.
A drainage bleb can become infected months or years later. Studies put the risk of a bleb related infection inside the eye at roughly 2.8 percent per year on average, and it is sight threatening, so any red, painful, or sticky eye needs urgent care.
Surgery can speed the development of a cataract, and there can be temporary blurring, a droopy eyelid, or double vision while the eye settles.
Surgery aims to stop further loss, not to restore sight already lost. Some eyes need more than one procedure, and drops are sometimes still needed afterwards.
Glaucoma is a lifelong condition that needs regular pressure checks and field tests. A bleb infection can appear long after you are home, and adjusting or revising drainage often needs the operating surgeon. Agree before you travel who will monitor your eye and manage any complication.
Six questions before you pay.
A safe clinic answers all six in writing without flinching. Vague answers, pressure to book quickly, and prices far below the market are the warning signs that matter most. We do not name clinics, so use these to judge any you are sent.
Recovery, and what happens once you are home.
First days
The eye is often red and watery and vision blurry. Use the drops as directed, wear any shield at night, and avoid rubbing or straining.
First weeks
Pressure is checked and the bleb is reviewed. Some clinics adjust stitches or use injections to fine tune drainage during this stage.
1 to 3 months
Vision settles and the surgeon confirms whether the pressure is controlled. Drops are sometimes reduced or stopped.
Lifelong
Pressure can rise again and a bleb can become infected years later, so regular checks continue for life wherever you had surgery.
Glaucoma is lifelong. The most delicate adjustments and any revision often need the operating surgeon, and a bleb infection can appear long after you are home and needs urgent local care. Agree who manages monitoring and complications before you travel.
Standard travel insurance rarely covers elective procedures or their complications. Read the policy closely and consider dedicated medical complications cover before you book.

The things everyone asks.
Will glaucoma surgery improve my eyesight?
Usually not. The aim is to lower eye pressure and protect the sight you still have, not to restore vision already lost. Be wary of any promise of better vision.
Do I have to pay for glaucoma surgery?
Not in the UK. Glaucoma threatens sight, so assessment and treatment are provided on the NHS. Paying privately or going abroad is usually about timing or technique, so check your options at home first.
How much does glaucoma surgery cost?
Private trabeculectomy in the UK commonly costs about £3,000 to £5,000 per eye, with around £3,500 a typical figure. Abroad, in markets such as Turkey, prices are often quoted from about $1,680 to $2,700 per eye. These are indicative ranges, reviewed April 2025.
Is glaucoma surgery safe?
It is generally safe but it is surgery on the eye. The pressure can rise again over time, and a drainage bleb can rarely become infected, reported at roughly 2.8 percent per year on average, so lifelong monitoring matters.
What if I have a problem once I am home?
A bleb infection needs urgent local care, and fine adjustments or revision often need the operating surgeon. Agree aftercare and who is responsible before you travel.
