Claim 0:
1. A planning device for generating control data for a treatment device for eye surgery, which generates at least one incision in a cornea by application of a laser device, the planning device comprising:
a calculating processor that determines the at least one incision in the cornea selected from a group consisting of a cap incision, a lenticule incision, an access incision and a combination of the foregoing,
wherein the calculating processor determines the cap incision and the lenticule incision such that together the cap incision and the lenticule incision at least partially circumscribe and at least partially isolate a lenticule that is removable from the cornea via the access incision,
wherein the calculating processor determines the at least one incision in the cornea based on data of a refraction correction, and generates a control data set for actuating the laser device for the at least one incision in the cornea,
wherein the planning device is configured such that a prior change in thickness of a corneal epithelium is taken into account in planning,
wherein the prior change in thickness of the corneal epithelium comprises a thickening caused by a prior treatment; and
wherein the planning device is configured to transmit the control data set to the laser device and the control data set is used to operate the laser device thereby generating the at least one incision in the cornea by operation of the laser device.
