An irradiation system for opthalmological applications includes: a radiation source (1) for changing the biomechanical properties of the cornea； an optical system for directing the radiation towards the tissue； a beam-splitter (3) which couples out a part of the radiation directed towards the tissue for measuring or monitoring purposes； the beam-splitter also being set up in order to combine a further radiation of a different wavelength with the first-mentioned radiation； a controller for controlling the system, including a sensor； a mechanical stand (16) for supporting an irradiation unit (17)； and interfaces for exchange of data.
