The device has a base station (11) with a light source (51) to generate light pulse with high rates, and an application head (3) inserted in an eye. A scanner (52) is arranged in the station to deflect the light pulse into a scanning direction. An optical transmission system transmits the deflected pulse from the station to the head and interacts the deflected pulse to the slow-scan movement of a light projector (58) of the head in another scanning direction. The station is integrated in an excimer laser system.
