SMILE laser eye surgery, what to ask.

The one honest thing
SMILE treats short sight and some astigmatism, not long sight, and a touch up is less straightforward than with other methods. Ask what happens if the correction is not complete.
Quick answer

What should you ask?

Start with whether you are genuinely a candidate, because SMILE only suits certain eyes. Then confirm exactly who will operate and how often they perform SMILE, what the quoted price includes, what the plan is if the correction is not full, and who provides your follow up. If you are travelling, the answer on a touch up and aftercare matters as much as the price.

The points here are general and drawn from reputable ophthalmology sources, reviewed May 2025. They are prompts for your own consultation, not a substitute for a personal eye assessment. We never name a clinic or surgeon.

Ask if you are a candidate

The question that comes first.

SMILE is keyhole laser correction that removes a small disc of tissue to reshape the cornea. It only works for the right eyes.

Am I a suitable candidate, and how did you decide? SMILE is approved for short sight, in the region of up to about ten dioptres, and for astigmatism up to roughly three dioptres. It does not treat long sight. Ask which of your numbers were measured and whether your prescription has been stable for about a year, since an unstable prescription is a reason to wait.

Did my scans rule out a thin or irregular cornea? A full assessment should map the shape and thickness of your cornea to make sure there is enough tissue and to rule out keratoconus, which is a reason not to have laser correction. Ask what your corneal thickness was and whether it leaves a safe margin.

I have dry eyes, does that change things? SMILE uses a smaller incision than some other methods and is often discussed as gentler on the surface nerves that drive dryness. If dry eye is a worry for you, ask how your tear film was assessed and what they expect afterwards.

Ask about the surgeon and the risks

Who operates, and what can go wrong.

Who exactly will perform my surgery, and how often do they do SMILE? Get the operating surgeon named in writing, not just the clinic. SMILE involves a manual step where the surgeon removes the tissue disc, so it is fair to ask about their SMILE specific experience and their own outcomes.

What are the risks in my case? Laser correction is generally safe but not risk free. Ask about dry eye, glare and halos at night, the chance of under or over correction, and the small risk of infection or a problem removing the tissue disc. Ask what is done to reduce these and the plan if one happens.

What is the plan if the result is not full? A touch up after SMILE is less straightforward than after some flap based methods and is often done with a surface laser instead. Ask what enhancement they would use, when, and whether it is included or charged again, especially if you are abroad.

Ask about cost and follow up

What the quote really covers.

A headline price means little until you know what is inside it and who cares for you afterwards.

What is included, and what is extra? Ask whether the price covers the full assessment, both eyes, the surgeon fee, the facility, all the drops, and every follow up visit. Confirm whether any enhancement within a set period is included and the currency you will be billed in.

What if something is not right? Ask who is responsible if you need a return visit or a touch up, and whether that is included or charged again.

Who provides my follow up? If you travel for surgery, this is the question that protects you. Find out how soon you can fly, who reviews you once you are home, whether a local eye professional can check your healing, and how you reach the surgeon quickly if a problem develops. A plan that ends when you board your flight home is not enough.

Common questions

The things everyone asks.

Who is SMILE suitable for?

It is approved for short sight up to around ten dioptres and astigmatism up to roughly three dioptres, with a stable prescription and a healthy cornea of adequate thickness. It does not treat long sight. Only a full assessment can confirm if it suits your eyes.

Is SMILE better for dry eyes than other methods?

It uses a smaller incision and is often described as gentler on the corneal nerves linked to dryness. If dry eye concerns you, ask how your tear film was assessed and what they expect for you.

What if I need a touch up?

An enhancement after SMILE is less straightforward than after some flap methods and is often done with a surface laser. Ask what they would use, when, and whether it is included, particularly if you go abroad.

What are the main risks?

Dry eye, glare or halos at night, under or over correction, and a small risk of infection or a problem removing the tissue disc. Ask your surgeon about the risks in your case and the plan if one occurs.

What should I ask if I have it abroad?

Ask who operates, what the price covers for both eyes, how soon you can fly, how a touch up would work, and exactly who provides your follow up once you are home.
