Abstract: The invention relates to a contact glass for ophthalmic surgery. Said glass comprises a lens body that is held in a frame and a front lens surface that is designed to be placed against the eye. According to the invention, the front lens surface is concave and follows a surface curvature (K) and an annular gap is formed at the edge of the front lens surface between the lens body and the frame, said gap being used to apply a negative pressure in order to fix the contact glass to the eye. The frame is designed to follow the contour of an imaginary continuation of the surface curvature (K), or at least does not project beyond the latter.

Abstract: An endoprobe for ophthalmic microsurgery for intraocular treatment of the eye and that affords a surgeon good visibility regardless of the distance from the treatment site in the eye. The endoprobe includes a stainless steel cannula enclosing one or more optical fibers and a laser fiber. A distal end of the optical fibers can be closed by a transparent lens-shaped structure such that an illuminating light transmitted through the optical fibers is radiated and transmitted laser light can exit from the laser fiber, or such that the laser fiber is embedded in a transparent shaped element. The laser fiber may have a covering for transporting light. The laser light may be injected directly into the laser fiber and the illuminating light is injected via at least one optical element into the covering of the laser fiber or into the transparent shaped element.

Abstract: The present invention is directed to a surgical method, particularly for procedures on the brain, in which it is possible to select the tissue to be treated. In the method according to the invention, a probe is positioned in the area of the diseased change and tissue selection is activated in that different electrical and/or electro-magnetic stimulus signals which can be preadjusted or modulated are sent to the tissue. Healthy tissue parts can be distinguished from pathologically changed tissue parts by evaluating the responses to these stimuli. When the stimulus response is absent or unexpected, the corresponding therapeutic or surgical treatment is carried out by means of the same probe at the selected site. Otherwise, the probe is repositioned and the tissue selection is activated again.
