Custom PRK - Photo-Refractive Keratectomy.
Unlike LASIK which creates a corneal flap, PRK applies the laser treatment to the top surface of the cornea. No corneal flap is created, which eliminates corneal flap complications. PRK is considered by some to be a safer option for those with a more active lifestyle, or who work in a more physical profession such as a policeman or firefighter. It is also used on patients with a corneal thickness too thin to safely create a flap in LASIK. Disadvantages include a longer recovery time than LASIK, and slightly more discomfort for a few days while the corneal epithelium heals. PRK patients should not expect to achieve their final vision for a few weeks.
