Squint Surgery in Ireland — Costs, Waiting Times & EU Options
Squint (strabismus) surgery adjusts the muscles that move the eye so both eyes line up. It's done in children and adults to improve alignment, reduce double vision and, in children, help the eyes work together. It's usually a day case under general anaesthetic.
What is a Squint Surgery?
A squint is when the eyes point in different directions, either all the time or some of the time. Six small muscles control each eye’s movement, and if they don’t work in balance one eye can turn in, out, up or down.
Squint surgery moves or tightens one or more of these muscles on the surface of the eye to change its position. The eye is not removed from the socket. In some adults, adjustable stitches allow the surgeon to fine-tune alignment shortly after surgery.
Who needs this surgery?
Squint surgery may be recommended for:
- Children whose squint hasn’t been corrected by glasses, patching or other treatment
- Adults with double vision caused by a squint
- Adults with a long-standing squint that affects confidence, eye contact or work
- Squints caused by nerve problems, thyroid eye disease or previous injury, once stable
In children, glasses and patching for a lazy eye usually come first. Surgery improves alignment but does not replace treatment for a lazy eye.
How the procedure works
Orthoptic assessment
Detailed measurements of the squint in different directions guide exactly which muscles to adjust and by how much.
Anaesthesia
Children always have a general anaesthetic. Adults usually do too, although some procedures can be done under local.
Adjusting the muscles
Through a small opening in the clear membrane over the white of the eye, the surgeon repositions or shortens the chosen muscles.
Dissolvable stitches
The muscles and membrane are secured with dissolvable stitches. Adjustable stitches may be fine-tuned later the same day in adults.
Recovery and home
Most patients go home the same day with antibiotic or steroid drops.
Where can you have a Squint 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.
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 Squint Surgery
The eye will be red, sore and watery, and double vision may occur temporarily. Simple painkillers help.
Children can usually return to school within a week. Avoid swimming for about two weeks.
Redness fades gradually. Your orthoptist will check alignment and how the eyes are working together.
Alignment can change over time, and a minority of patients need a further operation.
Risks and considerations
Squint surgery is generally safe. Possible risks include:
- Under- or over-correction, sometimes needing further surgery
- Double vision, usually temporary
- Redness that takes several weeks to settle
- Infection or a stitch reaction
- Very rarely, damage to the eye or a lost or slipped muscle
Squint Surgery — your questions answered
Is squint surgery only for children?
No. Adults can have squint surgery at any age, to reduce double vision or improve the appearance of a long-standing squint.
Will my child still need glasses after surgery?
Often yes. Surgery corrects alignment, but glasses may still be needed for focusing, and patching may continue for a lazy eye.
Is squint surgery cosmetic?
No. Correcting a squint can restore eye contact, reduce double vision and help the eyes work together, and is provided in the public system.
Can squint surgery be done abroad?
Yes, under the Cross-Border Directive with a referral, though children's surgery is usually best arranged close to home with their usual orthoptic team.
