• What is the difference between lasik surgery and PRK surgery?

  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.
