    摘要: An ophthalmic surgical microscope (100) has a microscope main objective (101) and a viewing beam path (105) which passes through the microscope main objective (101) for visualizing an object region. The ophthalmic surgical microscope (100) includes an OCT-system (140) for recording images of the object region (108). The OCT-system (140) includes an OCT-scanning beam (142) which is guided via a scan mirror arrangement (146) to the object region (108). An optic element (147) is provided between the scan mirror arrangement (146) and the microscope main objective (101). This optic element (147) bundles the OCT-scanning radiation exiting from the scan mirror arrangement (146) and transfers the same into a beam path which passes through the microscope main objective (101). Alternatively or in addition, the ophthalmic surgical microscope (100) includes an ophthalmoscopic magnifier lens (132) which can be pivoted into and out of the viewing beam path (105) and the OCT-scanning beam (142).

    摘要: The invention relates to a device for reducing pressure variations in a fluid flowing in an aspiration branch of a surgical system, which pressure variations are generated by a pump that delivers in a non-continuous manner in the active operating state, with a diffuser arrangement which is arranged, in the aspiration branch, upstream of the pump in the direction of flow of the fluid. The invention also relates to a surgical system, in particular an ophthalmic microsurgical system for lens surgery.

    摘要: A surgical microscope (100) has an illuminating module (120). The illuminating module contains an illuminating optic which images a field diaphragm (124) to a parallel illuminating beam path at infinity. The field diaphragm (124) is illuminated by a light source. The illuminating optic includes a first lens assembly and a second lens assembly which functions to image the field diaphragm (124) into the object region (108) via the microscope main objective (101) of the surgical microscope (100). An in-coupling element (128) is provided between the first lens assembly (125) and the second lens assembly (126) and this in-coupling element couples the OCT-scanning beam into the illuminating beam.

    摘要: Functional tissue areas in a tissue region are located by illuminating the tissue by measurement illumination. Stimulation in the functional tissue areas leads to a change in at least one optical property of the reflected measurement illumination compared to the original measurement illumination. The functional tissue areas are located based on the change in the at least one optical property of the reflected measurement illumination by determining the difference between a stimulation image of the tissue region obtained during the stimulation and a comparison image of the tissue region obtained without stimulation. The difference may be formed from at least one image recorded with the measurement illumination and at least one image recorded without the measurement illumination to bring about an increase in contrast. An obtained image may be corrected on the basis of the determined topography of the tissue region to bring about an increase in contrast.
