LASER DEVICE AND METHOD, IN PARTICULAR OPERATING METHOD FOR A LASER DEVICE, FOR GENERATING IRRADIATION CONTROL DATA FOR A PULSED LASER

摘要

2.1 It is known in laser ablation to correct the irradiation control data determined from a target ablation profile with respect to the energy of the laser pulses for refractive surgical treatment of the cornea depending on the impingement angle of the laser beam. The shape of the beam profile and the surface inclination of the cornea can be taken into consideration. The invention is to enable an even better agreement of the actually created shape with the target ablation profile. 2.2 A position of a (current) vertex of the surface to be ablated relative to an optical axis of the laser is determined and used for generating the irradiation control data. According to the invention, it was found that by considering the actual position of the vertex relative to the optical axis of the laser, the accuracy of a surface ablation, in particular of a laser surgical treatment of the cornea, can be improved, if said vertex and an ocularly fixed reference point, such as the puncture point of the optical axis through the surface of the cornea, do not coincide. 2.3 The invention can be used in ophthalmology.
