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.
Although vision may fluctuate slightly during the first few days and also shift slowly for 6 to 12 months, most of the healing is complete within 3 to 6 months. With nearly a decade of experience with PRK, we know that the procedure is stable, with no evidence of late-onset complications.
