Nidek NAVEX LASIK System with
OPD (Optical Path Diffrence) Scan.

The Potential Benefits of Customized LASIK Greater chance of achieving 6/6 vision Greater chance of achieving better than 6/6 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 Increased ability to restore best corrected vision if healing problems develop Customized LASIK not only improves the potential for 6/6 vision, it has the potential to restore eyes to better than 6/6 vision. The visual system is actually capable of seeing 6/5 or better, that is letters twice as small as the 6/6 letters on an eyechart. Most people cannot see beyond 6/6 because of very subtle imperfections within their visual system. Wavefront technology allows the surgeon to first map these subtle visual imperfections and then develop a laser treatment plan to correct them. The first patients ever treated worldwide with customized LASIK were in July 1999. Using Wavefront technology in the European trials a high percentage of patients treated with customized LASIK were able to achieve better than 6/6 vision, and even those that did not, still appreciated improvements in their night vision and contrast sensitivity. "Customized LASIK utilizes wavefront technology to correct not only the prescription of the eye but to treat any subtle imperfections within the visual system to improve both the safety and visual outcome potential for patients" Customized LASIK takes into account the curvature and smoothness of each cornea, the thickness of the cornea, any astigmatism and the pattern of that astigmatism, and an individual's pupil size. Wavefront technology analyzes the entire visual system from the corneal surface through the crystalline lens of the eye, all the way back to the retina. It actually looks at the whole eye and the way in which that eye sees the world to develop a truly personalized laser treatment plan. Wavefront analysis occurs across the entire 6mm optical center and represents a far more detailed assessment of the visual system, optimizing any imperfections to create the most ideal laser vision correction treatment pattern specific for that individual. Therefore, Wavefront technology not only provides more precise information for the treatment plan but far more information than ever before across several hundred points within the central vision zone to be treated. Currently, all patients with - 4.00 diopters of myopia, for example, are treated with a standard LASIK program for that degree of nearsightedness. However, each patient may differ in their precise corneal shape, their corneal thickness and their pupil size, as well as any number of other variables not accounted for routinely in standard LASIK programs. While standard LASIK programs work wonderfully, the advantages of customized LASIK cannot be overstated. customized LASIK will create the ideal pattern for each patient taking a multitude of variables into account. Instead of utilizing just the information from your prescription and a single central reading of a corneal curvature map, customized LASIK analyzes the entire visual system and develops a Wavefront Map that truly analyzes the cornea and visual system across hundreds and hundreds of points within the central vision zone. Each point mapped then guides the laser beam to provide the most ideal vision correction profile.
