Recovery from PRK surgery is a little longer. For the first few days while the corneal epithelium regenerates, PRK patients usually report hazy vision, some soreness, and light sensitivity. This typically clears up after the first few days, and most PRK patients are able to drive and return to work around Day 4 or 5.
PRK, or Photorefractive Keratectomy, is a procedure that differs from LASIK because it does not involve the creation of a corneal flap. Instead, the Excimer laser beam is applied directly to the surface of the cornea. By eliminating the flap creation step, the risk of flap complications is eliminated allowing for an effective and precise correction.
