What is eye tracking?
Your eye will move during surgery. Eye-tracking technology ensures your safety when this happens. Compensating for eye movement is a key factor in ensuring that the laser delivers its beam in exactly the right place. There are different methods (video infra-red, 3D, LADAR), all of which involve detecting the position of your eye. There is a minor lag between the laser noticing your eye has moved and compensating for that movement. All trackers, to date, provide approximately the same level of delay time – most operate with a delay of less than ten milliseconds (one hundredth of a second).
