Laser Vision Correction, or Refractive Surgery, is used to correct nearsightedness, farsightedness, and/or astigmatism by reshaping the cornea, or clear front part of the eye, so that light traveling through it is properly focused onto the retina. Laser Vision Correction is currently one of the most frequently performed elective procedures. It is a highly effective outpatient procedure that is suitable for most prescriptions, to improve vision and eliminate or reduce the need for eyeglasses or contact lenses. The most common types of refractive surgery are PRK (PhotoRefractive Keratotomy) and LASIK (Laser-Assisted-In-Situ Keratomileusis). The laser, which delivers a cool pulse beam of ultra-violet light, is used on the surface of the cornea in PRK and underneath the corneal surface in LASIK. The usual healing time is a few days for most patients. Patients are placed on eye drops, to promote comfort and reduce swelling. Dr. Younger will recommend which procedure, either PRK or LASIK, is best for you based on your screening eye exam, topography (corneal map), the thickness of your cornea, and your individual visual requirements. The advantages of each type of procedure will be discussed at your pre-operative visit. Most qualify for Laser Vision Correction. However, there are certain people who are less than ideal candidates, such as those under age 21, patients with other eye diseases and patients with very large pupils, thin corneas, or untreated dry eyes.
