A method of generating control data for ophthalmic surgery and ophthalmic surgical apparatus and methods

摘要

For a method for generating control data for an ophthalmic surgical treatment device (1) which separates tissue layers in the eye cornea (5) by means of a laser device (E), wherein a contact lens (25) has a contact surface during operation of the laser device (E) Cornea (5) deformed into the shape of the contact surface, to which the contact surface is first placed with a contact surface vertex on a corneal vertex and then pressed against the deformation of the cornea, the method comprising the steps of: the control data of the laser device (E) are generated in that they specify coordinates of target points (28) in the cornea (5) for the laser device (E) and in the generation of the target point coordinates the deformation of the cornea (5) is taken into account during operation of the laser device (E ) is present due to the contact glass (25), it is provided that in the consideration of the deformation fol The following steps are carried out to determine a deformation-induced displacement of a point P in the undeformed cornea (5): 1a) to the point P, a point O on the front surface of the undeformed cornea (5) is determined 1b) a distance $ I1 between the corneal vertex S and the point O is determined, where the distance $ I2 is the arc length on the undeformed cornea (5), 1c) it becomes a point. ..
