No, the final visual result is the same with LASIK or PRK, however the healing time is longer with PRK. With PRK the epithelium regenerates, typically by 5 days, but it takes a while for the epithelium to smooth out in order to see well. With LASIK 99% of patients can drive within 24 hours after having the procedure. With PRK it is advised not to drive until the contact lenses are removed which is usually in about 5 days. It may take 2 to 4 months after PRK for your best vision to be obtained.
