Photorefractive Keratectomy (PRK)

PRK is an elective, outpatient laser procedure to improve vision and reduce the need for eyeglasses or contact lenses for patients with nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

Prior to LASIK, PRK was the most commonly performed laser vision correction procedure. PRK differs from LASIK as it is performed on the surface of the eye and no flap is created during the PRK procedure. PRK may be recommended for people with larger pupils, thin corneas, or those who have other corneal issues.

Custom PRK provides an additional level of data about your vision requirements using the wavefront technology as discussed with LASIK. This additional data is then used by your surgeon to customize your PRK procedure to your individual vision requirements.

To accomplish the reshaping, the surgeon first removes the protective surface layer (epithelium) from the cornea. The epithelium is regenerated within three to five days. Your surgeon will then smooth the area and then proceed with applying computer-controlled pulses of cool laser light to reshape the front surface of the eye.

The PRK laser process is completed in 30-60 seconds. However, you will be at our office for approximately two hours.

Post-operatively, PRK patients are fitted with a bandage contact lens to improve their comfort while the eye is healing. Once healed, usually in three to five days, the bandage contact lens is removed by the surgeon.
