Abstract
The invention is directed to a process for the targeted application of therapy radiation in the treatment of diseased areas in the eye by means of a therapy beam which is directed into the eye through an applicator. In order to determine the parameters characterizing the diseased area, an image of the fundus of the eye to be treated is produced. The parameters characterizing the shape and/or size of the area to be irradiated and controlling variables are derived from this fundus image and are further processed by a computer. A control device is controlled by means of these parameters and controlling variables and adjusts or displaces an actuating arrangement corresponding to the shape and/or size of the area to be irradiated, which actuating arrangement changes the shape and/or size of the cross section of the therapy laser beam or changes the direction of the therapy laser beam in a plurality of coordinates and is arranged in the beam path of the therapy beam.
