This informational video describes Schwind Amaris 6-D active eye tracker. The 1st and 2nd dimensions of eye movements are lateral movements. The 3rd and 4th dimensions are rolling movements caused by a tilting of the head or of the eye. The 5th dimension describes the rotations around the visual axis the cyclotorsion of the eye. The 6th dimension describes eye movements along the z-axis caused by movements of the head or the eye closer or further away from Schwind Amaris. Before the Schwind Amaris came onto the market, standard eye trackers only adjusted lateral eye movements. The cornea rotates along the eyeballs rotational center. In a process new to refractive surgery, the Schwind Amaris eye tracker balances all those eye rolling displacements. Static and dynamic cyclotorsion control by the Schwind Amaris compensates for torsional differences of the eye between a patient in upright and supine position as well as torsional movements of the eye during ablation. With the Schwind Amaris, eye movements along the z-axis are compensated with active z-tracking. In addition to pupil recognition, the limbus is also simultaneously detected. If the pupil center shifts due to various light conditions the Schwind Amaris eye tracker compensates for this.
