Your eyes are unique-truly distinctive with mild imperfections that are different from anyone else’s. While conventional LASIK has been a complete revolution in vision correction, Wright Vision Center offers the latest in 3-deminsional laser vision correction technology: Custom LASIK powered by Bausch & Lomb Zyoptix. Custom LASIK is a procedure that enables Dr. Wright to further customize the LASIK procedure to your individual eyes. Using Wavefront technology, originally developed for use in high-powered telescopes to reduce distortion when viewing distant objects in space, we can now identify, measure and correct imperfections in and individual’s eye 25 times more precisely than glasses or contact lenses. In clinical studies, Custom LASIK has been able to provide patients with:
 

·  A greater potential of 20/20 vision

·  Potential for better vision than possible with contact lenses or

   glasses

·  Less incidence of glare and halos at night

 

 

Standard prescriptions for glasses, contacts, or traditional LASIK procedures can correct ordinary vision defects such as myopia, hyperopia, and astigmatism. But other irregularities associated with the eye's optical system could not be addressed until the advent of wavefront technology in custom LASIK. Several types of visual imperfections, referred to as lower- and higher-order aberrations, exist within the eye and may affect your vision (the amount of these aberrations vary from person to person). Previously, only lower-order aberrations (such as nearsightedness, farsightedness and astigmatism) could be measured and treated. Higher-order aberrations may also have a significant impact on vision and have been linked to glare and halos. Now Custom LASIK may help to further customize your treatment of these higher-order aberrations that, in the past, could not be adequately treated with glasses, contacts or conventional LASIK treatments. Our doctors will recommend the best procedure for you based on your personal aberrations.

 

The Technology of Custom LASIK

 

The Bausch & Lomb Zyoptix system, using wavefront technology, provides the most comprehensive analysis of your eye, allowing Dr. Wright to formulate a personalized LASIK procedure completely individualized to you. Custom LASIK using a wavefront analyzer to measure the way light travels through your eye. The wavefront analyzer creates a customized 3-D map of your eye by sending a safe ray of light into your eye. The light is then reflected back off the retina, out through the pupil. This reflection creates up to 9,600 data points that are received and arranged by the machine into a unique pattern that captures your lower- and higher-order aberrations. All of these visual irregularities are then displayed as a 3-D map, referred to as a wavefront map. This information is then electronically transferred to the laser (in wavefront-guided systems), and computer-matched to the eye's position. This map provides information about the unique visual characteristics of your eye which adds an additional level of data about your vision, enabling Dr. Wright to further customize your vision correction.

 

Potential Benefits of Wavefront-Guided Custom LASIK

 

Wavefront technology is groundbreaking because it has the potential to improve not only how much you can see, visual acuity measured by the standard 20/20 eye chart, but also how well you can see, in terms of contrast sensitivity and fine detail. This translates into a reduced risk of post-LASIK complications, such as glare, halos, and difficulty with night vision. How much you see depends on your lower-order aberrations associated with common refractive errors including myopia, hyperopia, and astigmatism, which traditional LASIK can treat. How well you see can depend on presence of the type and numbers of visual distortions known as higher-order aberrations, which can include irregularities other than common refractive errors. These higher-order aberrations can create problems such as decreased contrast sensitivity or night vision, glare, shadows, and halos. However, higher-order aberrations do not always affect vision. Unlike traditional LASIK, Custom LASIK treats both lower- and higher-order aberrations. Custom LASIK's advantage lies in the area of quality of vision:

 

·  Greater chance of achieving 20/20 vision

·  Greater chance of achieving better than 20/20 vision

·  Reduced chance of losing best-corrected vision

·  Reduced chance of losing visual quality or contrast sensitivity

·  Reduced chance of night-vision disturbances and glare
