Abstract

A planning unit produces control data for a treatment device for eye surgery which produces at least one cutting surface in a cornea of the eye using a laser unit. The planning unit includes a calculation module for establishing a cornea cutting surface. The calculation module is configured to establish the cornea cutting surface based on data of a refraction correction, to produce a control data set for actuating the laser unit for the cornea cutting surface, and to determine the cornea cutting surface in such a way that the cornea cutting surface contributes to fixing an implant in an interlocking manner.
