LASIK, one of the biggest breakthroughs in eye surgery, is a surgical procedure that uses non-thermal technology to change the shape of the cornea in order to improve vision. LASIK, which is actually an acronym for Laser-Assisted in Situ Keratomileusis (though few people ever know about it), meaning “reshape the cornea with laser.”
There are other kinds of refractive surgical procedures, but LASIK is the most advanced. Although LASIK and PRK (Photorefractive Keratectomy) use the same type of laser, their procedures are different with the way the stroma, the middle layer of the cornea is exposed. In PRK, the top layer of the cornea is scraped to espose the stromal layer while in LASIK, only a flap is cut in the layer and then folded back.
