Photorefractive Keratectomy (PRK)

Eye exam
Photorefractive keratectomy, or PRK, is the predecessor of LASIK, and it can be performed to correct nearsightedness, farsightedness, and astigmatism. PRK is often used for patients who are not good candidates for LASIK because of thin corneas. During PRK surgery, Dr. Ahdoot will use a microkeratome blade or femtosecond laser to remove the entire epithelium (top layer) of the cornea before modifying the stroma (middle section) with an excimer laser to correct your vision.
