WaveFront System
WaveFront® system was born of astrophysics from the desire of astronomers to reduce distortions when viewing distant objects in space through high-powered telescopes. The technology has since been adapted to accommodate the aspirations of LASIK surgery. As a result, we now have a means to measure imperfections in your eye up to 25 times more precisely than the standard methods that were previously available.
In the past, eye surgeons used trial lenses and a device known as a phoropter to measure imperfections. Prescriptions were hence limited to a fixed level of laser vision correction regardless of unique imperfections of vision.
Several features make the WaveScan® Wavefront system highly effective in laser vision correction. The use of WaveScan® technology allows the creation of various optical maps. A WavePrint® map allows for the charting of optical irregularities. This map is unique to your eye and contains a detailed analysis of your vision from which your LASIK surgeon can design the optimal vision correction treatment. Difference maps allow your LASIK surgeon to track changes in the eye from pre-operative and post-operative comparisons.
WaveScan® technology is capable of providing a point spread function that demonstrates to your LASIK surgeon how you would see a point source of light.
All of the data from any pupil shape can be contributed to the system for accurate reconstruction in therapy. Furthermore, the system is capable of capturing and treating irregularities of large pupils up to 7mm in diameter.
Combining the VISX® Star S4 IR Excimer Laser system with WaveScan® Wavefront technology results in a unique form of LASIK therapy known as CustomVue® Wavefront-Guided LASIK. It is called CustomVue because not only can it correct myopia, hyperopia, and astigmatism, as accepted with previously available technology, but also the other unique imperfections of your eye.
Note: Results from FDA clinical studies: CustomVue® treatment can improve vision beyond that possible with the use of contact lenses or spectacles.
