Device and method for producing control data for the surgical correction of the defective vision of an eye

A device for generating control data that control a laser system for surgical correction of defective vision of an eye of a patient, wherein:

• the laser system comprises a laser for emitting laser radiation, optics for focusing the laser radiation to a focus and a scanner for shifting a position of the focus;
• the device generates the control data to be adapted to control the laser, the optics and the scanner to cut the cornea by focusing the laser radiation into the cornea of the eye and by shifting the position of the focus within the cornea;
• wherein the control data includes data to control the scanner to shift the position of the focus within the cornea;
• wherein the device generates the control data such that the laser, the optics and the scanner, during operation under the control data, emit and focus the laser radiation such, that a volume in the cornea is isolated, the removal of which volume from the cornea effects a desired correction of the defective vision;
• and
• to determine the control data, the device is configured to calculate a radius of curvature RCV* of the cornea reduced by the volume;
• wherein the radius of curvature RCV* is locally varying.
