TREATMENT APPARATUS AND METHOD FOR PROVIDING CONTROL DATA FOR AN OPHTHALMOLOGICAL LASER OF A TREATMENT APPARATUS FOR THE LASER-INDUCED REFRACTIVE INDEX CHANGE

Abstract

The invention relates to a treatment apparatus (10) and a method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10) for the laser-induced refractive index change. As steps, the method includes determining (S10) treatment positions (16) in a cornea (14) of an eye, which are intended for the change by the laser-induced refractive index change; determining (S12) an orientation of collagen fibers (30) to be expected in the cornea (14) in the respective treatment positions (16) based on collagen fiber data of the cornea (14); setting (S14) a polarization property (24, 26) of a laser beam (20) of the laser (12) based on the orientation of the collagen fibers (30) to be expected for a respective treatment position (30); and providing (S16) the control data, which includes the set polarization property (24, 26) for the respective treatment position (16).
