Before you go
- Stop contact lenses for as long as the clinic asks, so the scans are accurate.
- Bring your current glasses and your last prescription.
- Expect drops that blur your sight for a few hours: don't drive yourself.
- Allow up to a couple of hours.

What they measure
- Your prescription, with and without drops that relax focusing.
- Corneal thickness and a map of its shape.
- Pupil size in dim light, your tear film and eye pressure.
- The back of the eye.
The questions to ask
- Who will operate, and will I meet them before the day?
- Are you on the Medical Council's Specialist Division in ophthalmology?
- Which treatment do you recommend for my eyes, and why not the others?
- What result is realistic for me, and will I still need glasses for anything?
- What are the most common problems you see, and how often?
- What exactly is included in the price, per eye and for both, and for how long?
- Is a top-up included, and until when?
- How many check-ups are there, where, and what does a later one cost?
- Who do I ring at night if something worries me?
- Is the deposit refundable if I change my mind?
After the assessment
Give yourself at least a week between meeting the surgeon and deciding, as the Royal College of Ophthalmologists advises, and check the deposit is refundable. A clinic that pushes you to book on the day is a reason to walk away.
Questions people ask
How long is a laser eye surgery assessment?
Often an hour or two, with drops that blur your sight for a few hours after.
Is the assessment free?
At some clinics. Others charge up to €200, sometimes taken off the treatment price.
Should I meet the surgeon at the assessment?
Yes, or at a separate visit before the day. The surgeon who operates should advise you in person.
