    LASIK surgery is usually performed to correct myopia, hyperopia and astigmatism. LASIK use a blade called a microkeratome or an excimer laser to cut a corneal flap during the surgery so that the corneal surface can be reshaped. While PRK (Photo Refractive Keratectomy) is another popular choice. This surgery reshapes the surface of the cornea without cutting a flap. They just use a laser to deliver cool pulses of ultraviolet light directly on the cornea.

    With a full name of Laser In-Situ Keratomileusis, LASIK is usually performed to correct myopia, hyperopia and astigmatism. Among all of the surgeries, only LASIK cuts a corneal flap during the surgery. LASIK uses a laser to apply the corneal tissue under the flap. In this way the corneal surface can be reshaped. In other words, a necessary amount of corneal tissues are removed. Until now, LASIK is the most popular vision eye surgery among the public. PRK (Photo Refractive Keratectomy) is another popular choice. This procedure is also capable of curing nearsightedness, farsightedness and astigmatism in mild and moderate forms. PRK involves no corneal cutting. During a PRK surgery, a laser delivers cool pulses of ultraviolet light directly on the cornea. During this process, the corneal surface will be reshaped. As a forerunner of LASIK, PRK is also a popular option today.
