How does Epi-LASIK Work?
Epi-LASIK is also very similar to PRK. However, rather than using dilute alcohol and a spatula to brush away the surface cells of the cornea, the cells are removed in a sheet with an instrument called an epikeratome. The laser is then applied to the cornea to correct the vision, and a bandage contact lens placed after the laser is done. Some doctors feel that this technique, which avoids the use of alcohol to loosen the surface cells, may promote faster and more comfortable healing of the cornea. As this is a relatively new procedure, very few clinical studies have been done to support this opinion one way or another. What are the main differences between PRK, LASEK and Epi-LASIK versus LASIK surgery? In LASIK surgery, a thin flap of cornea is made, lifted back then the excimer laser applied underneath to correct the vision. The flap is then replaced. Healing is very rapid, with the eyes feeling mostly normal within a day or two. Most surgeons will perform LASIK on both eyes on the sam
