What is PRK (Photorefractive Keratectomy) and how is it different from LASIK?<\/div>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Laser eye surgery performed on the cornea consists of two stages: the first stage is preparing the cornea, and the second stage, which is the main stage, involves shining the laser beam. Unfortunately, the naming of these procedures is based only on the first stage. In PRK, only the surface layer of the cornea, called the “epithelium,” is removed, and then the laser is applied to the cornea. In LASIK, however, a thicker layer, about 150 microns thick, is removed as a flap from the cornea, and after the laser treatment, this flap is placed back in its original position. The second stage of both procedures is the same, and both are performed using a type of laser called an excimer laser.<\/p><\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
