Glaucoma surgery, the questions that protect you.

Glaucoma surgery lowers the pressure in the eye to protect the sight you still have. It does not bring back vision already lost, and the condition needs lifelong monitoring. Here are the questions to ask before you book, wherever you are sent. We never name a clinic.

The one honest thing

This is treatment for a chronic, sight threatening disease, not elective surgery. Lifelong follow up at home is essential, which makes travelling for it a serious decision.

Quick answer

What should I ask a clinic?

Ask what the surgery is meant to achieve, since it lowers eye pressure to protect remaining sight rather than restore vision already lost. Ask which type is recommended and why, who performs it and with what qualification, and what the risks are. Above all, ask how the lifelong monitoring this condition needs would be managed once you are back home.

A clinic that answers these plainly and in writing is the one to trust. Any promise to restore lost vision, or a plan with no thought for ongoing care at home, is a serious warning sign. This is general information, not medical advice.

How to choose and what to ask

Six questions before you pay.

A safe clinic answers all six without flinching and puts the answers in writing. Use them to judge any clinic you are sent, wherever it is. We never name clinics.

What is this surgery meant to achieve?

The goal is to lower eye pressure and slow further damage, protecting the sight you have. It does not restore vision already lost. Make sure the clinic is clear and honest about this aim.

Which type of procedure, and why mine?

Options range from minimally invasive surgery with quicker recovery to trabeculectomy or a drainage tube, which lower pressure more but carry more risk. Ask why the recommended type suits your glaucoma and how it compares to drops or laser.

Who performs it, and with what credentials?

Ask the name and qualification of the ophthalmologist, their experience with this specific procedure, and whether you can verify them on a public register. Glaucoma surgery is specialist work.

What are the risks and the recovery?

Ask about risks such as infection, bleeding, low or high pressure afterwards, the chance it does not work, and the possible need for further surgery. Ask how long recovery takes and how it would affect a flight home.

How will my records reach my eye team at home?

Glaucoma is a long term condition usually managed by a local eye team. Ask for full records, pressure readings, scans, and details of the surgery in a form your own ophthalmologist can use to keep monitoring you.

What does the price include, and follow up?

Ask for an itemised price covering the assessment, the surgery, medication, and post operative checks, and what happens if pressure is not controlled or a complication appears once you are home. Line up your home eye team first.

Warning signs

The red flags that should stop you.

A promise to restore lost vision

Glaucoma surgery protects remaining sight, it does not bring back vision already lost. Any clinic that claims otherwise is misleading you and is a reason to walk away.

No plan for ongoing care

If a clinic treats this as a one off with no thought for the lifelong monitoring glaucoma needs, or no clear handover to your eye team at home, think very carefully.

Risks brushed aside

A clinic that downplays the real risks, or will not say who is operating and with what experience, is not giving you the honesty this decision deserves.

Get Matched with a vetted clinic

Ask the right questions, of vetted clinics.

Send one brief and we route it to vetted clinics that are honest about what glaucoma surgery can and cannot do, explain the type and risks clearly, and plan for the lifelong follow up near home. You choose, with no pressure.

Free and no obligation. Accredited clinics only. We never sell your details.

How we make money: the guides are free and no clinic can pay to be named, ranked or recommended. We never name clinics. Get Matched is an optional service that helps keep the guides free and independent of any one clinic; using it is always your choice and you are never charged. How this works.

Common questions

The things everyone asks.

Can glaucoma surgery restore my sight?

No. The aim is to lower the pressure in the eye and slow further damage, which protects the sight you still have. Vision already lost to glaucoma cannot be brought back, so be wary of any clinic that suggests otherwise.

What types of glaucoma surgery are there?

They range from minimally invasive procedures with quicker recovery to trabeculectomy or a drainage tube, which lower pressure more but carry more risk. Laser treatments are another option. Ask which suits your case and why.

Will I still need drops afterwards?

Sometimes. Surgery can reduce or remove the need for pressure lowering drops for some people, but others still need them. It is not always a permanent fix, and pressure can rise again, so ongoing monitoring matters.

Why does follow up matter so much for travelling?

Glaucoma is a lifelong condition that needs regular pressure checks and scans. Surgery does not end that. If you travel for it, the monitoring still has to continue at home, so plan that handover carefully before you go.

What if there is a problem once I am home?

Sudden pain, a drop in vision, or growing redness need urgent care. Agree in advance who to contact, arrange a local eye team to take over your care, and keep your full records and surgery details to share with them.
