Laser eye surgery is a procedure that corrects vision impairments such as myopia, hyperopia, and astigmatism using a highly precise laser. It is also known as refractive surgery or vision correction surgery. Other synonyms for laser eye surgery include laser vision correction, laser refractive surgery, LASIK (Laser-Assisted In Situ Keratomileusis), PRK (Photorefractive Keratectomy), LASEK (Laser-Assisted Sub-Epithelial Keratectomy), and Epi-LASIK (Epithelial Laser In Situ Keratomileusis). The main goal of these procedures is to reshape the cornea to enable the eye to focus better so that the patient can see more clearly without the need for glasses or contact lenses.
