A: 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 after five 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 five days. It may take two to four months after PRK for your best vision to be obtained.
