Types of Laser Eye Surgery
LASIK uses the laser to create a thin flap on the cornea that is lifted, under which the remaining corneal tissue is reshaped. The flap is then put back into place to facilitate healing.
LASIK surgery offers some advantages over other laser surgeries, including less postoperative discomfort, faster healing time, and reduced chance of corneal haze.
Photorefractive keratectomy (PRK) surgery is another type of refractive surgery involving an excimer laser, but it differs significantly from Lasik surgery.
During PRK, the surface layer of the cornea is removed with either the aid of alcohol, the excimer laser, or a rotary brush and the remaining cornea is then reshaped using the excimer laser. After, a contact lens or an eyepatch is used to protect the cornea as it heals.
