MALE VOICE 1: The excimer laser can be used to correct nearsightedness by either photorefractive keratectomy also called PRK or LASIK. In PRK the cornea of the eye is directly vaporized by the laser beam, sculpting a type of prescription onto the surface of the eye. The vision generally returns within about a week and there may be some discomfort for a few days.
LASIK, although technically more involved takes only about five minutes to perform and results in improved vision the day after surgery with only slight discomfort the day of the procedure. LASIK is performed worldwide and although currently being studied in this country is available at our center as well as standard PRK.
ALK or automated lamellar keratoplasty.
