Glaucoma & Complex Cataract Surgery in Ireland — Costs, Waiting Times & EU Options
Glaucoma surgery lowers the pressure inside the eye to protect the optic nerve and preserve your remaining sight. It's usually considered when drops and laser treatment aren't controlling the pressure, and is often combined with cataract surgery.
What is a Glaucoma & Complex Cataract Surgery?
Glaucoma is a group of conditions where the optic nerve is damaged, usually because pressure inside the eye is too high. Vision lost to glaucoma can’t be restored, so the aim of treatment is to stop further damage.
Surgery creates a new drainage route for fluid to leave the eye. Options include a trabeculectomy (a small drainage channel under the white of the eye), drainage tubes or shunts, and minimally invasive glaucoma surgery (MIGS), tiny stents often inserted during cataract surgery. Complex cataract surgery, for example in eyes with glaucoma, previous surgery or weak lens support, falls into the same group of procedures.
Who needs this surgery?
Glaucoma surgery may be recommended if:
- Eye pressure remains too high despite drops and laser treatment
- Your glaucoma is still getting worse on visual field tests or scans
- You can’t tolerate glaucoma drops or find them hard to use reliably
- You need cataract surgery and also have glaucoma, so both can be treated in one operation
How the procedure works
Assessment
Your eye pressure, optic nerve scans and visual fields are reviewed to choose the most suitable operation.
Anaesthesia
The eye is numbed with a local anaesthetic injection or drops, often with light sedation.
Creating drainage
Depending on the procedure, the surgeon creates a drainage channel, inserts a tube, or places a micro-stent to help fluid leave the eye.
Combined cataract surgery
If you also have a cataract, it may be removed and replaced with an artificial lens during the same operation.
Close follow-up
You'll be seen frequently in the first weeks so the surgeon can adjust healing and pressure, sometimes by removing stitches or using injections.
Where can you have a Glaucoma & Complex Cataract Surgery?
Compare the public system, private hospitals in Ireland, and HSE-reimbursed treatment in the EU.
Public (HSE)
Free at the point of care with a GP or consultant referral. Waiting times vary widely by hospital, region and clinical urgency; your hospital or the NTPF (ntpf.ie) can tell you where you are on the list.
Private in Ireland
Ask the hospital for a fixed-price quote covering the hospital fee, consultant and anaesthetist fees. Check your health insurance plan for cover, excesses and any approved-hospital list before booking.
EU Cross-Border
Can usually be arranged under the EU Cross-Border Healthcare Directive with a referral from your GP or consultant. As this is normally a day case, prior authorisation is not usually needed, but confirm with the HSE National Contact Point before you book. You pay upfront and claim back up to the Irish public cost. Glaucoma surgery needs several follow-up visits in the first weeks, so agree in advance whether these happen abroad or with your Irish ophthalmologist.
Check if you're eligibleHave your surgery in weeks, not years
Under the EU Cross-Border Healthcare Directive, you can be treated in an accredited EU/EEA hospital and claim the cost back from the HSE — with a GP or consultant referral.
Check whether you qualify and what you'd get back.
*Reimbursement is capped at the cost of the same treatment in the Irish public health system. Travel, accommodation and any balance above the HSE rate are not covered. Pre-authorisation applies to treatment involving an overnight hospital stay.
Recovering from a Glaucoma & Complex Cataract Surgery
The eye may be red, uncomfortable and blurry. You'll use several drops, including steroids and antibiotics, and wear a shield at night.
Frequent check-ups are normal. Avoid heavy lifting, bending, swimming and rubbing the eye.
Pressure and vision settle. Many people can stop some or all of their glaucoma drops, though some still need them.
Glaucoma needs lifelong monitoring even after successful surgery, as the drainage can scar over time.
Risks and considerations
Glaucoma surgery carries some specific risks:
- Eye pressure becoming too low, causing blurred vision, usually temporary
- Scarring that blocks the new drainage, which may need further treatment
- Faster development of a cataract
- Infection, which can occur months or years after a trabeculectomy
- Bleeding inside the eye, which is rare
Report a sticky, red or painful eye after a trabeculectomy urgently, even years later.
Glaucoma & Complex Cataract Surgery — your questions answered
Will glaucoma surgery restore my sight?
No. Glaucoma damage can't be reversed. Surgery aims to stop further loss of vision by lowering the eye pressure.
Can glaucoma surgery be combined with cataract surgery?
Often yes. Minimally invasive stents and some other procedures are commonly done at the same time as cataract surgery.
Will I still need eye drops afterwards?
Some people can stop their drops, while others need fewer. Your surgeon will guide you based on your pressure readings.
Can I have glaucoma surgery abroad and claim it back?
Yes, provided it is a treatment the HSE would provide in Ireland, you have a referral, and it is carried out in a public or private healthcare provider in another EU/EEA country. You pay upfront and claim back up to the Irish public cost. Travel and accommodation are not covered. Glaucoma surgery needs close follow-up, so plan how your post-operative checks will be handled before you travel.
