Photorefractive keratectomy, or PRK, has been used in the United States since 1995 to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Due to medical issues such as thin corneas, certain patients are not suitable candidates for LASIK but have excellent results with PRK. The procedure uses anesthetic eye drops and takes only a few minutes. During PRK, the top layer of the cornea is removed to expose the cornea’s mid-section, or stroma. Then, in a manner identical to that of the LASIK procedure, a computer-controlled excimer laser vaporizes specific corneal tissue using bursts of ultraviolet light. Patients typically experience some discomfort for one to two days after the procedure while the cornea’s top layer regenerates. The visual outcomes of PRK are generally as good as the results from LASIK.
