PRK - Photorefractive Keratectomy

PRK was the first laser procedure approved in the United States. The difference between PRK and LASIK is that there is no flap in PRK. The surface corneal cells, called the epithelium, are completely removed in PRK, then the laser gently reshapes the underlying corneal surface the same as in LASIK.

After the procedure these corneal epithelial cells that were completely removed must regenerate or grow back. This process can take anywhere from 2-4 days. And during this time patients can experience moderate pain. Some patients that may not be good candidates for LASIK may be a good candidate for PRK. This can be discussed during a patient's complimentary consultation appointment.
