What is PRK?

Photo-Refractive Keratectomy (PRK) may be the best choice for vision correction in some patients. The procedure is very similar to that of LASIK, but no flap is created. During PRK, the surface cells of the cornea, called the epithelium, are removed.

The surgeon then uses the excimer laser to reshape the cornea to your customized prescription. Laser treatment usually lasts an average of 30 seconds depending on the amount of correction necessary.

A soft contact lens is placed on the eye to act as a “bandage” to promote the comfort and healing of the surface cells. This contact lens will be removed by the doctor within 4-7 days after the surgery.


LASIK and PRK have very similar outcomes, with PRK taking slightly longer to heal. Slade & Baker Vision also ran the FDA clinical trial for PRK approval.

Ideal PRK Candidates

People who are 18 and older with a history of stable vision.

People who are nearsighted, farsighted, and/or have astigmatism.
