Photorefractive keratectomy (PRK) is a laser eye surgery — specifically a type of refractive surgery. A refractive problem is where your eyes don’t bend light properly, which keeps you from seeing your best.
Photorefractive keratectomy (PRK) is a laser eye surgery — specifically a type of refractive surgery. A refractive problem is where your eyes don’t bend light properly, which keeps you from seeing your best.
During PRK, an eye surgeon uses a laser to reshape your cornea. This laser, which delivers a pulsing beam of ultraviolet light, is used on the surface of the cornea, not underneath a corneal flap as in LASIK. LASIK has a shorter recovery period and less pain after the procedure.
