What is PRK?
Photorefractive keratectomy (PRK) is a type of eye surgery that makes use of laser to reshape the cornea. PRK is primarily designed to correct vision problems such as astigmatism and farsightedness. It changes the way the eyes focus light, reducing the need to corrective lenses.
How is PRK Done?
The eye surgeon uses an alcohol solution to remove a central area of your corneal epithelium. An excimer laser is then used to accurately reshape the curvature on the surface of your cornea. This part is computer-controlled. After removing microscopic amounts of tissue in a precise pattern using highly specialized laser, a bandage or soft contact lens is placed on the cornea. Once the new epithelial cells grow back, the eye doctor can now remove the bandage contact lens.
