A process for configuring a laser device comprising: selecting a pulse length within a range from 1 ps to 1 ns； selecting a wavelength for the laser radiation within a range from 300 nm to 400 nm or within a range from 800 nm to 1100 nm； ascertaining a set of parameter values of the laser device that when the laser device is operated with these parameter values a two-dimensionally extensive separation of tissue of human corneal or lenticular tissue is achieved by stringing together local sites of damage, the set of parameter values including the selected pulse length, the selected wavelength, and values for at least one of the following parameters: a pulse energy, a pulse repetition rate, a fluence per radiation pulse, a number of pulses per site of damage, a scanning speed of a scanning apparatus of the laser device, and a focus diameter.
