How it differs
Where LASIK lifts a flap, SMILE works through an opening a few millimetres wide. The laser shapes a lens-shaped disc inside the cornea and the surgeon removes it. That suits people in contact sport and may be gentler on dry eyes.
Who it suits
Adults with short sight, with or without some astigmatism, and a prescription steady for at least a year. In the United States it is approved from 22, for short sight between -1 and -10 and astigmatism up to 3.
Finding it in Dublin
SMILE needs a specific laser. Fewer clinics on the island offer it than offer LASIK or LASEK, so ask at the start which treatments a clinic actually does. If it doesn't offer SMILE, ask whether LASEK or LASIK would do the same job for your eyes.
Recovery and risks
Most people are back to normal activities after a day or two. Keep water out of your eyes for a few days. You can't drive yourself home after treatment. Have someone collect you or book a taxi, bring sunglasses because light will feel harsh, and leave the Luas or DART for another day. Risks include glare and halos at night, inflammation, rarely infection, and under- or over-correction needing a top-up.
Questions people ask
Can I get SMILE in Dublin?
Ask clinics directly: few on the island have the laser for it. LASIK and LASEK are widely available.
Is SMILE dearer than LASIK?
Usually a little: about €2,600 an eye against €1,500 to €2,600 for LASIK.
Does SMILE treat long sight?
No. Long sight is treated with LASIK, LASEK or, later in life, lens replacement.
