Cyclotorsion in particular can result in misalignment, producing undercorrection of astigmatism.
Zyoptix ACE takes the accuracy and predictability of refractive surgery (LASIK) to new levels by dynamically compensating for intraoperative cyclotorsion (eye rotation), constantly adjusting the laser position in relation to involuntary eye movement by patients.
Zyoptix ACE is designed to further improve the accuracy and predictability of refractive surgery outcomes by dynamically compensating for intraoperative cyclotorsion (eye rotation).
The Technolas Perfect Vision laser was the first to introduce true iris recognition technology, being capable of recognizing every eye on the planet, and combine it with real-time rotational eye tracking in order to respond to any eye movement, including cyclotorsion.
