About Lasik

What is LASIK?
Laser Assisted In-Situ Keratomileusis. It combines microsurgery with excimer laser treatment.
The laser removes predetermined microscopic (1000th mm with each pulse of laser energy) amounts of the tissue from the deeper layers of the cornea. In order to treat this part of the cornea, a surgical flap of corneal tissue is lifted to expose these deeper corneal layers.
