PRK, or photorefractive keratectomy, is a refractive procedure that can correct astigmatism, nearsightedness, and farsightedness. Before LASIK became as popular as it is today, PRK was the most common refractive surgery procedure. Among patients who are precluded from undergoing LASIK, PRK remains a popular choice. PRK requires a longer recovery time than LASIK, primarily because during PRK, Dr. Weinstein will manually remove the surface of epithelial cells before using a laser to reshape the inner cornea. These cells must grow back before excellent vision is restored.
