New Technologies in PRK Eye Surgery

PRK, also known as photorefractive keratectomy, is a type of laser refractive surgery that reshapes the cornea using an excimer laser. PRK is designed to treat myopia, hyperopia, and astigmatism. It is also the first refractive procedure approved by the Food and Drug Administration (FDA) that included the use of an excimer laser. PRK eye surgery is an outpatient procedure, which means you don’t have to stay in the office or hospital overnight. As with LASIK surgery, once a PRK procedure has been performed, it is permanent and irreversible.

PRK intervention

Your doctor starts PRK surgery by giving you anesthetic eye drops. When your eyes are completely anesthetized, the doctor removes the epithelial layer. An excimer laser is then used to flatten the surface of your cornea. While the doctor is performing the procedure, you will need to direct your gaze to a target area. During the procedure, it is important that you are comfortable lying down, flat on your back, for about 20 minutes. The procedure usually lasts between 15 and 20 minutes or less. As with LASIK, PRK surgery is performed on one eye at a time, but usually it is performed on the second eye about three months after the first procedure.

In which cases can Lasik surgery be performed?

Before you can elect a patient for Lasik surgery, the surgeon will determine if the procedure is possible.  For this, he must establish for each candidate a preoperative assessment as well as a medical interview.

The pre-operative assessment: it allows the surgeon to know if the eye has characteristics that may favor the occurrence of certain side effects. Several examinations can be carried out (corneal topography, measurement of the thickness of the cornea, ORA measurement for Ocular Response Analyzer etc.);

Medical interview: this is necessary for the surgeon to be able to detect any contraindications to this surgery (ophthalmological or other pathology, previous surgical history, etc.). It also makes it possible to know the patient’s expectations.
