After the procedure, the patient must wear special protective goggles at night for about a week. It is advisable to go home and rest with the goggles on for a few hours after the procedure. There is a checkup both a day after and a week after. Most people, like Miller, feel no pain during or after the procedure, and they walk out with the vision they want. Almost all patients get the vision they want with the second procedure.
Blindness is also a risk, as it is with any type of eye surgery.
