Photorefractive Keratectomy (PRK) is very similar to LASIK. In fact, PRK was being performed before LASIK even existed. Photorefractive Keratectomy set the course to make LASIK possible. The main difference between the two is that during LASIK the surgeon creates a flap in epithelial layer before using the laser to reshape the cornea underneath. In PRK, there is no flap. The surgeon simply removes the very top epithelial layer and then, as with LASIK, used the laser to reshape the cornea. The epithelial layer will regrow in a few days. PRK patients will take a few more days than LASIK patients to achieve the full results of their new vision but they can achieve the same visual results as LASIK patients, and since they did not have a flap created, there is no concern about potential flap complications. PRK is a good alternative for patients who have thin corneas, previous eye surgery, or other health factors that make them a poor LASIK candidate.
