A photorefractive keratectomy-better known as PRK-is a form of laser vision correction in which a laser eye surgeon removes the surface layer of the cornea and then reshapes the corneal bed with an excimer laser. The excimer laser portion of PRK surgery is the same as LASIK vision correction. This technique is usually used for people whose corneas are too thin for the flap required for LASIK.
Just like LASIK, PRK surgery can effectively correct nearsightedness (myopia), farsightedness (hyperopia) and astigmatism.
What is the difference between PRK and LASIK vision correction?
The difference is simple; in LASIK there is a corneal flap and in PRK there is no flap creation. Instead, the surgeon polishes away the outermost layer of the cornea. The visual outcomes are the same with LASIK and PRK, but with PRK surgery there is a slightly longer healing period.
Why do some people need and choose PRK?
PRK is a good option for patients with thinner than average corneas, or for patients with corneas that are "soft." Someone may also choose PRK surgery if they have a profession which comes with a much greater risk of getting hit in the eye and causing flap movement (e.g. boxers, martial artists, wrestlers).
