CustomVue Photorefractive Keratectomy (PRK)Photorefractive Keratectomy (PRK) is a laser vision correction procedure used by ophthalmologists to permanently change the shape of the cornea to improve the way it focuses light on the retina. CustomVue refers to the advanced technology that makes it possible for our physicians to achieve your best personal vision (see sidebar).
In the past, refractive errors (light rays not focusing precisely on the retina) could only be corrected with eyeglasses or contact lenses. Today, PRK is just one of many alternatives available to correct vision with a refractive procedure.
Each refractive procedure is performed in a different manner and suggested for you because it best suits both your visual and lifestyle needs. In the case of PRK, instead of creating an incisional flap in the cornea, as is done with the LASIK procedure, a very small amount of surface corneal cells are removed. With the laser, gentle pulses of concentrated, cool, ultraviolet light beams are then applied to modify the shape of the cornea. A contact lens is placed on the surface for the first few days and visual acuity is steadily gained over the first month.
In the past few years, a modified version of the PRK procedure was developed and is referred to as Epi-LASEK. It involves a gentle loosening of the most superficial layer of the cornea and the reshaping of the cornea with the excimer laser. The difference is that with Epi-LASEK, the loosened tissue is slid back in place on the cornea and a contact lens is placed on the surface to both protect the eye and provide patient comfort. Epi-LASEK allows the patient the benefit of a shortened healing process over the PRK procedure. Knowing that healing time is extended with PRK, why would I chose it over LASIK or Epi-LASEK?In recent years, PRK is not the most frequently requested procedure. While the procedure has its merits, the delayed healing process causes many potential patients to choose one of the alternative methods. There are, however, some instances when it is the only procedure for consideration due to a particular job requirement. This occurs in some isolated circumstances with certain branches of law enforcement professions.
