Tired of dealing with glasses and contacts? LASIK and PRK are two similar types of refractive surgery that correct common vision problems, such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia (blurriness), and astigmatism, to reduce or possibly eliminate your dependence on prescription eyeglasses and contact lenses.
LASIK (laser-assisted in situ keratomileusis) is the most common type of refractive surgery. It uses a highly-focused and precise laser beam to re-shape the cornea so that light entering the eye is more properly focused onto the retina, resulting in sharper vision. In most cases, LASIK is pain-free and completed within 15 minutes for both eyes.
PRK (photorefractive keratectomy) was the first type of refractive surgery before LASIK, and although it has a longer recovery time than LASIK, there are some advantages that make it preferable for some patients.
