Wavefront analysis works by measuring the distortion or irregularities of the eye, known as higher-order aberrations. When a ray of light first enters the eye, it passes through the cornea to the lens and vitreous, ultimately reaching the retina. As it bounces off the retina and returns back through the cornea, the wavefront analysis detects and documents these distortions, which are unique to each individual. Because each patient has a unique visual optical system, the wavefront data has been likened to a fingerprint.
Once the wavefront data has been documented for an individual patient, the next step is to use this information to utilize the excimer laser to correct the higher-order visual aberrations. The surgeon can then determine what adjustments must be made to the corneal surface to produce a clear, crisp image for the unique individual needs of each patient.
The use of wavefront technology to provide a more precise laser vision correction is known as, "Custom LASIK" or "Wavefront-Driven LASIK". Early data suggests that the 5-10 percent of patients who demonstrate higher-order aberrations are the patients that will significantly benefit from Custom LASIK treatments. Other patients may benefit from Custom LASIK to a smaller degree.

What is Zyoptix Wavefront LASIK? Zyoptix Wavefront LASIK is a revolutionary procedure for performing laser refractive surgery. Land-based telescopes use a technique called adaptive optics to cancel out the blurring effects of the Earth's atmosphere capturing stellar images that rival orbital telescopes for clarity. The FDA recently approved use of adaptive optics in ophthalmology which is called wavefront analysis.
Anderson & Shapiro utilizes Bausch and Lomb's Zyoptix Diagnostic Workstation to examine the way a laser beam, reflected from the retina, distorts as it returns from the interior structures of the eye. The analysis of the irregularities at the front of the lightwave emerging from the eye produces a precise three-dimensional map of the cornea and its imperfections also known as aberrations. Higher-order aberrations are distortions that cause glare, halos, and blurry images. The accuracy of the wavefront data allows our surgeons to combine total refractive error control, total corneal architecture, with the world's leading wavefront-guided excimer laser, the Technolas® 217z Laser Deck, to produce outstanding clinical results.
Why Choose Zyoptix Wavefront LASIK? More laser vision correction procedures are performed with Bausch & Lomb Technolas lasers worldwide than with any other system. The Technolas 217z Excimer Laser that we employ uses invisible, cool, ultraviolet light that causes virtually no damage to surrounding tissue, increasing its safety. A state-of-the-art feedback mechanism ensures every laser pulse is placed exactly as prescribed.
