Both LASIK and PRK treatments deliver great visual outcomes and are equally safe. However, the way in which each treatment is performed differs slightly. With LASIK surgery, a thin, hinged flap is created on the cornea in order for the laser to access the treatment area. With PRK, the cornea’s epithelial layer (the outer layer) is partially removed to expose the area, but no flap is created. PRK (and, IntraLase SBK) is recommended for patients who have thinner-than-average corneas. It is also better-suited for those whose profession puts them at greater risk of getting hit in the eye and causing flap movement (e.g., boxers, martial artists, wrestlers or patients more prone to blows to the face). In both procedures, the excimer laser sculpts the inner layer of the cornea to correct the refractive error. The only difference with PRK is that the healing time is longer and the number of post-surgery visits is greater. Based on the results of your pre-operative consultation, your eye care professional will recommend the best option for you and your eyes.
