With the ACE/DRET system integrated into the Zyoptix laser system, the LZW relies on absolute high-tech LASIK.
Like a fingerprint, a person's iris is unique and unmistakable. The Zyoptix-100 system creates a digital "map" of the iris, which forms the basis of the multidimensional eye tracker.
The eye tracker (ACE) records eye movements in all directions (x and y axes) during the operation in a fraction of a second, as well as up/down movements of the head (z axis). The system compares the position of the iris with the digital "map" stored on it and can thus automatically compensate for movements during LASIK (3D eye tracking).
The dynamic rotational eye tracker (DRET) also compensates for additional rotational or rolling movements of the eye. Thanks to the ACE/DRET system, the laser works with a previously unattained level of precision, especially in cases of astigmatism or pure nearsightedness or farsightedness.
