Since the FDA approved the use of the Excimer Laser for Laser Vision Correction, in 1995, millions of people in the US and around the world have been freed from the need for glasses and contact lenses. The technology that led up to the approval included radial keratotomy (RK), which has been all but abandoned, and PhotoRefractive Keratectomy (PRK) which is still used in selected patients who are not candidates for or who elect not to have LASIK. Epi-LASIK is the newest version of PRK and it results in more precise healing and less discomfort.
The FDA approval was originally for nearsightedness only, but as the technology has advanced, vision correction has been performed for several years for people with astigmatism and farsightedness as well and even just to get rid of reading glasses.
“I was tired of my glasses falling down my nose while I performed procedures…It’s amazing to wake up and see perfectly – the alarm clock, out the window – everything! Plus my 3 year old son now brags to his teachers that I am beautiful – because I don’t need glasses!” Dr. Joanna Luty, Pediatrics
In LASIK a protective flap is created in the front of the eye (cornea) with a microkeratome. The flap is then folded back to expose the deep layers of the cornea. Laser treatment is then performed using the Excimer Laser on the deeper layers to change the focal point of incoming light rays. The central cornea is flattened to correct nearsightedness, steepened for farsightedness and rounded for astigmatism. The flap is then repositioned and it adheres without the need for stitches.
In PRK and Epi-LASIK the surface (epithelial) cells are removed and the laser treatment is applied to the second layer of the cornea to change its shape and thereby its focal point. At the end of the procedure a bandage contact lens is placed, which remains for several days while the epithelium regrows. These procedures are generally not as comfortable as LASIK and take longer to heal than LASIK; however Epi-LASIK potentially gives better quality vision. Surface procedures involve no cutting and therefore are safer.
“Dr. Gold has changed my life. He put an anxiety I had about the surgery at ease and I have felt well taken care of at every point of treatment and follow-up. I have had 100% confidence in my care with Dr. Gold” Dr. Danielle Moreggi, Psychologist:
Wavefront Analysis is a wonderful technology that has been available for about 5 years. It provides an advanced method for measuring optical distortions in the eye. Measuring and treating these distortions goes beyond nearsighted, farsighted, and astigmatism determinations that have been used for over a century. As a result, Dr. Gold can now measure the eye much more precisely and customize the laser vision correction procedure according to each individual patient’s unique vision correction needs. The treatment is unique to each eye, just as a fingerprint is unique. Wavefront systems work by measuring how light is distorted as it passes into the eye and then is reflected back. This creates an optical map of the eye, highlighting individual imperfections.
During the patient evaluation process, Wavefront Analysis provides Dr. Gold with comprehensive individual diagnostic information, not available using earlier technologies. Thus, before surgery even begins, he is better able to determine the appropriate course of treatment.
“The results have been amazing I love skiing and scuba diving without glasses or contacts. I am so grateful for being able to see!” Dr. Amy O’Donnell, Neurologist
During treatment, Wavefront Analysis allows Dr. Gold to tailor the laser beam settings, making the surgical procedure itself 25 times more precise than conventional analysis. In this way, Wavefront technology offers the patients sharper, crisper, better quality vision, as well as a reduction in nighttime vision difficulties, such as haloes and glare.
Wavefront technology is an adjunct tool used to enhance an already safe and effective procedure. As the most common form of vision correction surgery, LASIK has already benefited millions of patients. The increased safety and the improved quality of vision benefits of customized procedures are an important technological advancement for patients and physicians alike.
