PRK (Photo-Refractive Keratectomy)
FDA approved since 1995, Photo-Refractive Keratectomy, better known as PRK, can treat nearsightedness, mild to moderate farsightedness and astigmatism. It was the first popular type of laser vision correction and laid the groundwork for the creation of LASIK. Like LASIK, PRK uses and Excimer laser to reshape the cornea to the desired shape, reducing or eliminating the need for glasses or contact lenses. Unlike LASIK, PRK does not involve the creation of a corneal flap. It begins by removing the epithelium cells on the outer most layer of the cornea. Dr. Dudee then uses the excimer laser to reshape your cornea to correct your vision. The epithelium will quickly grow back on its own in 3-7 days, but until it heals you can experience a scratchy sensation and blurry vision.
While PRK offers results that are just as amazing as those achieved with LASIK, it has a longer healing time and the results are not as immediate, which is why LASIK grew more in popularity. For some patients, however, PRK may be a better option. This includes patients who are not good LASIK candidates because their cornea is too thin or slightly too irregular.
Some patients may also be a better candidate for Dr. Dudee’s patented procedure, HDSA or High Definition Surface Ablation. To learn more about HDSA, click here.
