Photo Refractive Keratectomy
PRK (Photo Refractive Keratectomy) involves reshaping the curvature of the cornea with an excimer laser to correct nearsightedness or farsightedness with or without astigmatism. PRK was the first procedure approved by the FDA in 1996. PRK is performed by removing the surface layer of the cornea (epithelium is the “skin” of the eye) and applying the laser to directly to the layers beneath the surface.

How is PRK Different from LASIK?
PRK is essentially LASIK without the creation of a LASIK flap. PRK generally produces similar results to LASIK but the patient usually experiences more discomfort and has a slower recovery of vision than in LASIK as it takes several days for the epithelium to grow back.

What Vision Problems Can PRK Correct?
PRK has been approved by the FDA to correct nearsightedness (Myopia), farsightedness (Hyperopia), astigmatism (either combined with nearsightedness or farsightedness). Monovision is also an option with PRK for either nearsighted, farsighted or astigmatic eyes as well as with Presbyopia. Although Monovision PRK is an Off-Label Use of the lasers since it is not FDA-approved, a highly qualified LASIK expert can best advise you on whether you are a good candidate for Monovision PRK and perform this procedure if this is a viable option for you.
