1. A method for controlling an eye surgical laser for the separation of a volume body with a predefined posterior interface and a predefined anterior interface from a human or animal cornea, comprising:
controlling the laser by means of a control device such that it emits pulsed laser pulses in a shot sequence into the cornea, wherein the interfaces are generated by the generation of a plurality of cavitation bubbles generated by photodisruption by means of an interaction of the individual laser pulses with the cornea, wherein a minimum diameter of the volume body orthogonal to an optical axis of the volume body is determined depending on at least one diopter value for the volume body and on a preset thickness of the volume body viewed in a direction of the optical axis.
