Device for Treating Eye Tissue by Means of a Pulsed Laser Beam

An ophthalmological device for treating eye tissue of an eye comprising:

• a laser source which is configured to generate a pulsed laser beam;
• an application head having focusing optics and a patient interface, the focusing optics having a projection axis and being configured to focus the pulsed laser beam in the eye tissue onto a treatment point, and the patient interface having a central axis and being configured to fix the application head on the eye;
• a scanner system which is configured to direct the pulsed laser beam in the eye tissue onto treatment points on a treatment path;
• and
• a circuit which is configured to control the scanner system in order to incise an incision surface, which is symmetrical with respect to the central axis of the patient interface, in the eye tissue, the pulsed laser beam being directed onto treatment points on the incision surface on a first treatment path,
• wherein the circuit is further configured, in an event of a tilt of the eye with respect to the central axis of the patient interface, to determine an apex or nadir of a tilted incision surface, which is determined by a co-tilt of the incision surface corresponding to the tilt of the eye, to determine a transformed second treatment path, using the apex or nadir, the second treatment path determining treatment points on the tilted incision surface, and to control the scanner system in such a way that the pulsed laser beam is directed onto treatment points on the transformed second treatment path.
