What happens during LASIK eye surgery?
An instrument called a microkeratome or femtosecond laser is used to create a thin flap in the cornea, the clear front part of your eye. The cornea flap is peeled back (it doesn't hurt). The underlying corneal tissue gets reshaped using another laser so that it can properly focus light onto the retina. Then the cornea flap is put back in place.
The surgery usually takes about 10 minutes to complete.
