Claim:
1. An ophthalmological device for treating eye tissue by means of pulsed laser beams, comprising: a user interface configured to receive from a user a selected mode of operation, a laser system which is configured, in a first mode of operation, to generate a pulsed laser beam with a wavelength in the NIR (near-infrared) range and, in a second mode of operation, to generate a pulsed laser beam with a wavelength in the UVA (ultraviolet A) range, and a control system configured to set the wavelength of the pulsed laser beams depending on the user selected mode of operation, a focusing system comprising a projection optical unit, the projection optical unit including an optical system controlled by the control system, the optical system being configured for being adjusted by the control system to adjust an imaging surface and a spot size defined by the pulsed laser beam, for projection of the pulsed laser beam, the focusing system further having a drive system controlled by a plurality of zoom functions for controlling the optical system, the control system further configured to select one of the zoom functions depending on the user selected mode of operation, wherein in the first mode of operation, the control system selects a first zoom function configured to control the optical system: in the second mode of operation, the control system selects a second zoom function which differs from the first zoom function and is configured to control the optical system:
