Photorefractive keratectomy to correct vision defects (PRK)

Photorefractive keratectomy (PRK) is a laser eye surgery that can be used to correct vision defects such as nearsightedness, farsightedness, and astigmatism. During the procedure, a laser reshapes the cornea, which helps the eye focus light more accurately onto the retina. This can improve vision and reduce or eliminate the need for glasses or contacts. 

PRK has a good safety record and is typically an outpatient procedure, meaning most people can go home the same day. Recovery time may vary but usually takes several days or weeks for full results to become apparent.

PRK is a safe and effective treatment option in many cases, with most patients experiencing significant improvements in their vision following their procedure.
