During Laser-Assisted In Situ Keratomileusis (LASIK) surgery, the surgeon will cut a flap in your cornea and then fold it back. Your cornea will be reshaped using a precision laser. The flap will be lowered after surgery, and the cornea will repair itself as you heal.
LASIK is the most popular form of laser eye surgery in North America, with a satisfaction rate of over 90%.
An alternative to LASIK, photorefractive keratectomy (PRK) also changes the shape of the cornea. During PRK the top layer of the cornea is completely removed and a laser re-shapes the remaining layers.
