What is involved in a photorefractive keratectomy (prk)?

PRK: First it is determined if you are a good candidate for the procedure. Prk is done with eye drop anesthesia. You recline in a chair similar to a dentist chair, and an instrument is placed to hold the eyelids open. You look upward toward the laser opening. The surgeon checks the positioning, settings, and alignment, and proceeds with treatment. A bandage contact lens may be placed for comfort.
