Myopia is the medical term for nearsightedness. Currently, the most popular and successful surgery to treat the condition is called LASIK, short for Laser-Assisted In Situ Keratomileusis.
Basically, a flap of tissue is cut away from the top of the cornea; after which a carefully-controlled laser is used to carefully sculpt the cornea into a new shape (by vaporizing layers of tissue only a few micrometers thick); and finally the flap of tissue is carefully repositioned over the cornea and allowed to re-heal.
Prior to the refinement of LASIK surgery, the most popular procedure was known as radial keratotomy, which involved making very tiny cuts directly into the cornea in order to reshape it. (There's also photorefractive keratectomy, which substitutes a laser for the knife blade.) Of these, LASIK gives the best results with the lowest chance of side effects; though of course, any surgery carries inherent risk.

The PRK procedure flattens the cornea by vaporizing small amounts of tissue from the cornea's surface. Photorefractive keratectomy can be used to treat mild to moderate forms of myopia.
