The WaveLight Ex500 is worldwide the leading LASIK machine at present. It is the world’s fastest excimer laser which minimizes dehydration of the corneal bed to increase treatment outcome accuracy. That means better vision. SpeedEach “burst” of the Alcon EX 500 Laser lasts mere billionths of a second before the laser shifts to its next position-up to 100 times faster than some lasers. The machine uses a small-spot laser beam, which allows LASIK specialists to shape the cornea in finer, more gradual increments for a smoother surface with eye-tracking technology 8 times faster than some of the competition. Using the custom-optimized mode, the Alcon EX 500 Laser creates a “map” of your eyes and their unique characteristics to assist the surgeon in creating a personal vision profile. This map serves as a guide that helps doctors locate the eye’s exact treatment position, which is one of the most important factors in obtaining a more naturally shaped cornea and therefore an excellent refractive outcome, especially when correcting eyes with high astigmatism.
