CustomCorneaŽ, the most advanced laser vision correction available, is performed using Alcon's LADARVisionŽ system . Our LASIK technology measures your unique vision problems before surgery and creates a customized laser vision correction procedure to match your individual vision problems and make the exact correction your eyes need. CustomCorneaŽ goes beyond reshaping your cornea based on your prescription for eyeglasses or contacts. The procedure is completely customized to your eyes and your eyes alone. CustomCornea can help with other vision problems that could not be detected previously, known as higher order aberrations. Experts believe these aberrations can contribute to vision problems such as glare, halos and night vision problems.
