LASIK stands for Laser Assisted in Situ Keratomileusis. The Lasik laser eye surgery is used to rectify, myopia, hyperopia, and astigmatism. The procedure for lasik laser eye surgery involves two steps.

In the first step a flap is made in the stoma and the next step of the lasik corrective laser eye surgery involves removing of some of the tissue in the cornea with the laser.

The time taken for a corrective laser eye surgery like this is very less in the order of a few minutes. Another type of corrective laser eye surgery is the LASEK.

This is called the Laser Epithelial Keratomileusis.As the name indicates the flap is cut in the epithelium only. People who are not the best candidates for a LASIK laser eye surgery can go for a LASEK laser eye surgery.

Patients who have thin or flat corneas are the best candidates for a LASEK corrective laser eye surgery. One of the disadvantages of going for a Lasek corrective laser eye surgery is the long healing time and the discomfort experienced by the patient.

Another type of corrective laser eye surgery is the epi-lasik in which the epithelium is cut with an epikeratome instead of blade and alcohol. Pain with an epi-lasik is very less and faster healing is possible in this procedure.

Corrective laser eye surgery like the Lasik has replaced the older methods like the ALK that were used to treat myopia and hyperopia. The ALK procedure takes around one hour for the surgery.

Such procedures using PRK are called photoablation procedures. Ultraviolet radiation is used to remove tissue in the cornea in photoablation corrective laser eye surgery.
