Abstract: Improvements in respect of performing cataract surgery, and the result thereof, by application of a laser system. A device for cataract surgery, includes a surgical microscope or stereo microscope and a laser source. A module, consisting of a laser-coupling/deflecting unit, a laser-scan unit, and a focusing unit, can be attached to the surgical microscope or stereo microscope, in which at least one of these units can selectively be introduced between the surgical microscope and eye, and in which the focusing unit can scan a depth-of-focus range of greater than 1 mm.

Abstract: The invention relates to stereoscopic display system having a single display (7). Right and left partial images are sequentially displayed on the display (7). For the viewing, two separate component beam paths (21, 22) for viewing only left partial images (21) and only right partial images (22) and a switchover device (5, 9) are provided. The switchover device (5, 9) couples in the data, which is shown on the display, from a common part of the viewing beam path alternately into the two separate component beam paths in synchronism with the display of the right and left partial images on the display. In one embodiment, the switchover device includes a polarization switch (5) and a polarization beam splitter (9). The polarization switch (5) is arranged either in the illuminating beam path or in the common part of the viewing beam path.

Abstract: An OCT-supported surgical system includes an OCT module that includes a surface scanner, the position of which can be sensed by a position sensing unit, and an evaluation and display unit, which is connected to the OCT module and to the position sensing unit in order to be able to correlate a tissue-differentiated tomogram of a specimen sensed by the OCT module with preoperatively produced specimen data.

Abstract: A process for the optical spatially resolved determination of density distributions in biological tissues includes as a first step irradiating a biological tissue by directing a locally confined beam of electromagnetic radiation at an incidence position of the tissue; keeping the incidence position fixed; determining the thickness of the tissue being irradiated; and sensing and recording the directly transmitted radiation component and the scattered radiation component in a spatially resolved manner over a defined spatial angle. As a second step, the incidence position is changed and the first step is repeated. As a third step, the second step is repeated a number of times to obtain a reconstructive representation of the tissue through which the radiation has passed, based on the spatially resolved recordings of the transmitted and scattered radiation components and the tissue thickness as determined in each repetition of the first step.
