While LASIK is the most popular type of laser eye surgery performed today, it’s not right for everyone. If you’re not a good candidate for LASIK, PRK may be an effective alternative that will help you restore clear, sharp vision.
PRK (photorefractive keratectomy) is a procedure in which laser energy is used to reshape corneal tissue, allowing light to properly focus on the retina (the light-sensitive tissue lining the back of the eye) and thus correct vision. A cornea that is not ideally shaped will cause blurry vision at varying distances.
The difference between LASIK and PRK is that with LASIK a corneal flap is created and the laser is applied to the inner tissue of the cornea. With PRK, the epithelium (the outer layer of “skin” of the cornea) is removed and a laser is applied to the surface of the cornea. PRK can be used to correct low to high hyperopia (nearsightedness), myopia (farsightedness) and astigmatism (having an irregularly- or oval-shaped cornea rather than one that is round). As is true with LASIK, the entire PRK procedure takes only a few minutes to perform.
PRK may also be the best choice for individuals who lead very active lifestyles or work in high-risk fields such as law enforcement, aviation or the military, any of which carries a greater risk of eye injury. Because a corneal flap is not made during the PRK procedure, there is less of a chance of injury after this treatment should something come into contact with the eye.
