Traditional LASIK provides treatment similar to that which glasses or contacts would provide for a patient. Custom LASIK takes into account every patient’s individual visual needs and can treat higher-order visual aberrations that cause problems such as starbursts, halos and decreased contrast sensitivity. There is also a lower risk of complications with Custom LASIK, and the Wavefront mapping technology used in the procedure gives the surgeon an incredibly accurate and precise means of locating and correcting problems with the eye. Also, studies have shown that the possibility of achieving 20/20 vision is higher with Custom LASIK.
