Claim 13:
14. A method for separating a volume body with predefined interfaces from a human or animal cornea, comprising:
controlling of a laser by means of a control device such that it emits pulsed laser pulses in a predefined pattern into the cornea,
wherein the interfaces of the volume body to be separated are defined by the predefined pattern and a surface of the cornea and the interfaces located in the cornea are generated by means of photodisruption,
wherein the surface of the cornea is a surface of the eye artificially generated by means of ablation or displacement of the uppermost corneal layer and/or by means of production of a corneal flap;
wherein the laser is controlled such that the predefined pattern is processed starting from the surface of the cornea in the direction of an interface of the volume body spaced from the surface of the cornea, and
wherein the interface spaced from the surface of the cornea is generated transversely to the optical axis of the eye immediately above or within the Bowman's membrane or crossing the Bowman's membrane.
