Photorefractive keratectomy

Photorefractive keratectomy (PRK) is a laser eye surgery that corrects refractive errors like nearsightedness, farsightedness, and astigmatism. During the procedure, the outer corneal layer is gently removed, and an excimer laser reshapes the underlying corneal tissue to improve how light enters the eye, enhancing vision. The surface then heals naturally over a few days. PRK is an option for those who may not qualify for LASIK or prefer a procedure with no corneal flap. It generally provides long-lasting vision correction, though it may involve a longer recovery period.
