The Right Track for Vision Correction

About this technology

Overview

Alcon's LADARVisionR 4000 utilizes a laser radar (LADAR) eye tracking device for unmatched precision during LASIK vision correction surgery. The LADARTrackerT measures eye movements at a rate of 4,000 times per second, 4 times the perceived safety margin. It also employs a closed-loop system, which keeps the device locked on the eye at all times. Eye movement information is continuously relayed to the system, allowing the system to compensate for the movements. The LADARVision system has FDA approval for the correction of nearsightedness, farsightedness, and astigmatism. Eye surgeons across the country are utilizing the LADARVision 4000 for LASIK surgery. In October 2002, Alcon's LADARVision System, consisting of the LADARVision 4000 and the LADARWave wavefront measurement device, became the first to gain FDA approval for wavefront-guided LASIK. The resulting procedure, called CustomCornea, allows surgeons to measure and address visual distortions that previously went undetected. LADARVisionR is a registered trademark of Alcon.
