PRK (Photorefractive Keratectomy), is an elective, outpatient laser vision correction procedure to improve vision and reduce or eliminate the need for eyeglasses or contact lenses. In the PRK laser vision correction procedure, the laser surgeon utilizes the excimer laser to reshape the curvature of the eye for patients with nearsightedness, farsightedness and astigmatism.

PRK has been performed since 1986. Prior to LASIK, PRK was the most commonly performed laser vision correction procedure. PRK differs from LASIK as no flap is created during the PRK procedure. PRK may be suitable for people with larger pupils, thin corneas, have other corneal issues or dry eyes.

Custom PRK is a procedure that enables your laser vision correction surgeon to further customize the conventional PRK procedure to your individual eyes. Custom PRK provides an additional level of data about your vision requirements using wavefront technology. A device called a wavefront analyzer measures the way light travels through your eye and compares it to an eye with perfect vision. This device then creates a 3-D wavefront map that is uniquely yours, in the same way that your “fingerprint” is unique to only you. This additional data is then used by your Dr. Woolfson to customize the PRK laser vision correction procedure to your individual vision requirements.
