A computer-aided system include a data storage (18) with eye data (181), which defines a three-dimensional model of the eye, and a reference generator (113) for defining and storing a geometric reference in relation to the three-dimensional model of the eye. The system additionally includes a cut surface editor for defining and positioning cut surfaces in the three-dimensional model of the eye based on user instructions. Finally, the system includes a cut pattern generator (117) for, based on the positioned cut surfaces, generating and storing three-dimensional cut patterns for defining tissue cuts to be executed in a human eye by means of femtosecond laser pulses. The generation of a three-dimensional cut pattern permits the user to define tissue cuts made possible by femtosecond laser pulses in a targeted and efficient fashion in the three-dimensional model of the eye without having to undertake manipulations directly on the eye for this purpose.
