What is PRK?
PRK is used to treat myopia or nearsightedness. A pulsing excimer laser beam removes a thin layer of corneal tissue. This flattens the curvature of the cornea to improve its ability to refract light. As a result, most people can see clearly without corrective lenses.
Does it hurt?
Drops are used to numb the eye to eliminate any discomfort during treatment.
Individuals may experience a gritty sensation 24 to 48 hours following the procedure. A protective contact lens may be used for a few days while the surface of the eye heals. Temporary, mild visual side effects, such as light sensitivity, glare or halos, have also been reported in the weeks or months following treatment. The full benefits of corrected vision are usually realized one to three months later. One eye at a time is treated.
How long does it take?
The entire process, including preparation and follow-up instructions, takes about 30 minutes. The actual procedure lasts only 15 to 40 seconds
