Careful, normal only: means common; not good (2 very different issues). PRK outcomes very variable & often do not stabilize until 6 months out, or longer; the reason this Russian technique has been largely replaced by Lasik approaches. Even first generation Lasik was more reliable than PRK & Lasik has progressed through several generations. Suggest seeking out someone with lots of experience & worthy of your trust.
