The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea.

The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.
