Abstract

A laser slit lamp comprising a slit lamp base, a slit lamp head and a slit lamp microscope. The laser slit lamp is connected with an applicator. It comprises a device for uniting radiation from at least two radiation sources collinearly and for directing the radiation of a treatment beam or working beam onto the location to be treated in or on the eye of a patient, a device for generating a target beam or marking beam for targeting and observing the location to be treated in or on the eye, and an adjusting device in the applicator for changing the intensity and diameter of the working beam spot used for treatment. The radiation sources are laser radiation sources arranged in the slit lamp head, in the slit lamp base or in the slit lamp microscope for generating the working beam, illumination beam and/or target beam. Devices for control, regulation and monitoring are likewise arranged in the interior of the slit lamp.
