A planning device generating control data for a treatment apparatus for refraction-correcting ophthalmic surgery is provided, said apparatus using a laser device to separate a corneal volume, which is to be removed for correction, from the surrounding cornea by at least one cut surface in the cornea of an eye, said planning device comprising an interface for receiving corneal data including information on pre-operative cuts which were generated in a previous ophthalmic operation, and computing means for defining a corneal cut surface which confines the corneal volume to be removed, said computing means defining the corneal cut surface on the basis of the corneal data and generating a control dataset for the corneal cut surface for control of the laser device.
A method of generating control data for a treatment apparatus for refraction-correcting ophthalmic surgery, said apparatus using a laser device to separate a corneal volume, which is to be removed for correction from the surrounding cornea by at least one cut surface in the cornea, said method comprising:
A method of performing a refraction-correcting ophthalmic operation using a treatment apparatus comprising an interface for receiving corneal data including information on pre-operative cuts generated in a previous ophthalmic operation, computing means for defining a corneal cut surface and confining the corneal volume to be removed and defining the corneal cut surface on the basis of the corneal data and generating a control dataset for the corneal cut surface for control of a laser device, said control dataset containing information on an eyesight defect to be corrected, the laser device forming a cut surface in a cornea,
