LASIK: Custom Laser Treatments

The latest technological advance in laser vision correction is “custom” LASIK. “Custom” LASIK, which also goes by various other proprietary names, such as CustomVue™. This represents the next step in improving the outcome of laser vision correction beyond the excellent results already attainable by conventional means. This is possible because every eye and its associated refractive errors are unique, much like one's fingerprint, and recent advancements in technology now allow us not only to measure these unique refractive imperfections, but also to accurately and predictably eliminate them.

At the heart of “custom” LASIK procedures is the aberrometer, such as the VISX WaveScan™ Wavefront measurement system. By adopting technology originally developed for high-powered telescopes, these Wavefront measurement devices can identify and quantitate imperfections in the individual's eye 25 times more precisely than the standard methods used for eyeglasses and contact lenses. This information is then digitally transferred to the excimer laser for the treatment, providing a new level of precision and accuracy.

Typically, a “custom” LASIK procedure takes at most a few seconds longer than a conventional procedure. All aspects of the treatments are the same, with the main exception that the reshaping of the cornea by the excimer laser is based on the unique Wavefront information of the eye, rather than the conventional, non-customized measurements. Just like a conventional LASIK, there is no pain during the procedure, and most patients notice immediate results after treatment, with continued improvement in vision over several days.

Results of Clinical Study

A large clinical study, which was necessary for attaining FDA approval of this new and improved technology, highlighted the excellent results achievable with “custom” LASIK. In this particular study, one year after undergoing “custom” LASIK, 100% of the enrolled patients could pass a driving test without glasses or contact lenses. In fact, 98% of custom-treated patients could see 20/20, and a full 70% could see better than 20/20. Moreover, in this study, four times as many people were very satisfied with their night vision after “custom” LASIK as compared to their night vision before with glasses or contact lenses. Currently, “custom” LASIK is available to patients whose refractive error falls within the parameters set forth by the FDA. With additional clinical data constantly being submitted to the FDA, the eligibility for “custom” LASIK will surely be expanded. Patients interested in taking advantage of this new and exciting technology should discuss with the surgeon their candidacy for “custom” LASIK treatment.

Is the CustomVue™ Procedure for You?

Treatments are available for a variety of patients, including those with astigmatism, whether the astigmatism is associated with nearsightedness, farsightedness or mixed astigmatism. As a result, more than 92 percent of the U.S. population that requires vision correction, 21 years of age or older, are eligible for this life-altering procedure. Treatments are now available for people with: * myopia (nearsightedness) * myopia with astigmatism * hyperopia (farsightedness) * hyperopia with astigmatism * mixed astigmatism People with "mixed" or "irregular" astigmatism have vision that is often difficult to correct with eyeglasses or contact lenses. As shown in an FDA clinical study, with CustomVue treatment these individuals now have the potential to achieve better vision than is possible with glasses or contacts. CustomVue treatment offers the broadest range of wavefront-guided treatments available .
