1. A planning device for generating control data for a treatment apparatus for eye surgery, said treatment apparatus producing at least one cut surface in a cornea by application of a laser device, the planning device comprising:
a calculation application configured to define the at least one corneal cut surface at least comprising a lenticule cut and a cap cut; and
a focal position adjustment mechanism configured to receive specific output values from a control data record to adjust focus of the laser device through three dimensions,
the calculation application defining the at least one corneal cut surface and generating a control data record that controls the laser device to make the at least one corneal cut surface,
wherein an incision made by the laser is controlled by application of the control data record transmitted by the planning device so that laser pulses impinge mutually corresponding locations of the lenticule cut and the cap cut at a time interval of up to 10 seconds,
wherein the mutually corresponding locations of the lenticule cut and the cap cut are x- and y-coordinates in a plane perpendicular to a z-axis in a coordinate system wherein the z-axis extends perpendicular to the plane and through the lenticule cut and the cap cut.
