Excimer Laser for LASIK

Wavelight® Ex500 Excimer  Laser Technology San Diego LASIK Center® – Global Laser Vision

Chances are, several of your friends or family members are experiencing the joys of living without or limited dependency on glasses or contact lenses as a result of laser vision correction. You have heard the excitement in their voices, noticed the boost in their confidence, and watched the quality of their lives improve with new-found freedoms from contacts and glasses. It’s very probable that they had conventional LASIK or PRK and achieved superb results. Something has changed in the field of laser vision correction that makes the procedure safer and with even better visual results.

Now, people undergoing the new procedure Custom Optimized Lasik are experiencing fewer problems with night vision and a greater number of people are achieving 20/20 vision. The changes have come with new technological advances in the instrument that gathers the information that drives the laser correction, and with advances in the laser. The new technological advancement in the instrument that gathers the information is called a wavefront and topo guided technology. The new technological advancement that the information is then transferred to is our newest laser here at Global Laser Vision, the WaveLight® Ex500 Excimer Laser. This new, advanced procedure utilizing these two new technological advancements is called customized laser vision correction. Customized optimized LASIK or PRK can be performed on a majority of candidates and our complimentary Lasik consultation will determine your candidacy. This procedure is called custom optimized laser vision correction because the procedure corrects not only myopia, hyperopia, and astigmatism as we previously did, but it now corrects the other 100% unique imperfections of your eye. Now it’s important to understand that the LASIK and PRK procedures themselves have not changed, but rather the way we gather information for your correction, and in the laser, we use during these procedures.

Heavy patient demand for laser vision correction has inspired laser manufacturers and surgeons to make tremendous advancements in both Excimer laser technology and surgical techniques. When laser vision correction was first performed in 1988, only low to moderately nearsighted patients without astigmatism could be treated. Today, with the more advanced Excimer lasers, very low to moderately high degrees of nearsightedness, farsightedness, and astigmatism can be readily treated. And, for many patients who had large pupils, thin corneas, or other contraindications for laser vision correction, new surgical techniques now allow them to enjoy the benefits of clear vision without dependence on glasses and contact lenses that only a few years ago they would have been denied.

How the Procedure Works

The WaveLight® Excimer Ex500 Laser makes pulses of invisible ultraviolet light. Each pulse of light removes a microscopic layer from the front surface of the cornea, changing the curvature of the cornea ever so slightly.

Only a very small amount of tissue is removed, usually less than the thickness of a hair. Low amounts of nearsightedness, farsightedness, or astigmatism will require smaller amounts of tissue removal, and larger corrections will require greater amounts.
