ACE is a further development on the existing eye tracker and is able to dynamically (actively) follow the eye if it rotates in addition to movement in other directions (X, Y & Z).

This highly sophisticated application that uses Iris recognition and registration technology (similar to IRIS at the airports) ensures the treatment to the eye is applied in the same way as the information was acquired by the Zywave. The wavefront image is superimposed on the iris. The system tracks tiny eye movements and guides the laser to follow them. This makes sure that the laser treats the correct areas of your eye with phenomenal accuracy. The eyetracker incorporates advanced video tracking and reads the exact position of your eye at about 240 times per second. The laser also responds within 6 milliseconds, amongst the fastest response times available! The eyetracker forces the laser to stop treatment if your eye moves outside the laser treatment range.

A secondary benefit is the security of Iris Registration and knowing that your treatment is uniquely yours and cannot be mixed up between eyes or with someone else !
