Custom Laser Vision Correction surgery has been made possible by the development of several computerized devices to analyze how the human eye treats an incoming wave of light, or “wavefront”.
This wavefront analysis technology has been available for more than 5 years. It used to be thought that light enters the eye as a group of light rays. This thinking was adequate to determine an eye’s prescription in terms or nearsightedness or farsightedness and astigmatism.
When it became necessary to get more specific in the laser treatment of a particular eye’s refractive error, instead of treating only the prescription, it was realized that we need to think about the incoming light as a flat wave of light and then to determine how that eye distorts that wave of light. It is this distortion that is then treated with the laser in "Custom Laser Vision Correction".
Wavefront Analysis provides an advanced method for measuring optical distortions in the eye. This creates an optical map of the eye, highlighting individual imperfections. The treatment is unique to each eye, just as a fingerprint is unique.
Wavefront Technology functions as a roadmap for laser vision correction surgery, providing benefits to the patient during both the evaluation and treatment process. During the patient evaluation process, Wavefront Analysis provides the physician comprehensive individual diagnostic information, not available using earlier technologies. Thus, before surgery even begins, the surgeon is better able to determine the appropriate course of treatment.
During treatment, Wavefront Analysis allows the surgeon 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 and Epi-LASIK have 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.
Most patients considering Laser Vision Correction have at least some level of anxiety about their upcoming decision.
About LASIK Surgery
LASIK and Epi-LASIK have incredibly good safety records, but with a lower percentage of problems than other eye surgeries.
“I didn’t like wearing glasses in the OR because they would slip and I couldn’t push them back up. But without them, I couldn’t see across the room. I am so happy to have made the choice to correct my vision permanently. Thank you Dr. Gold and the staff at Liberty Vision for your wonderful care!”
“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”
