Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system includes: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further includes a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: An operating microscope (2, 48) for observing an eye (77) is provided. The operating microscope (2, 48) comprises a main objective (5) and a fundus imaging system (71) that is positionable in the beam path (7) between the eye (77) and the main objective (5), said fundus imaging system having an ophthalmoscopy magnifier (73). The main objective (5) of the operating microscope (2, 48) has a focal length in the range between 90 mm and 160 mm. The fundus imaging system (71) also can comprise an optics group (81), the dispersion properties of which are matched to the dispersion properties of the ophthalmoscopy magnifier (73) in such a way that the optics group (81) compensates a chromatic aberration of the ophthalmoscopy magnifier (73).

Abstract: A method of adaptive image acquisition includes obtaining a guide image of patient tissue; receiving an intraoperative image of a portion of the patient tissue from an imaging instrument; and storing the intraoperative image. The method includes comparing the intraoperative image with the guide image to identify at least one region of the guide image matching the intraoperative image; and determining whether the at least one region identified meets at least one accuracy criterion. When the at least one region meets the at least one accuracy criterion, the guide image is rendered with an indication of the at least one region on a display. When the at least one region does not meet the at least one accuracy criterion, the method includes receiving and storing a further intraoperative image; combining the further intraoperative image with the intraoperative image; and repeating the comparing and determining.

Abstract: A surgical microscope comprises microscopy optics, a camera, a display system and a controller comprising a data memory storing object data of at least one surgical tool. The microscopy optics are variable optics for changing an imaging scale of an imaging of a field of view onto the camera. The controller is configured to process the camera images and to identify the at least one tool in the camera images by object recognition using the object data of the at least one tool and the set imaging scale.

Abstract: An eye surgery system 1 comprises microscopy optics 3 and an OCT device 5 to generate a light-optical image and an OCT image of an eye fundus 11, a controller 29 and a visualization system 13, 41, 83. The controller comprises a data interface 97 for receiving a preoperative OCT image and may control the visualization system to display a representation of the received preoperative OCT image. The controller may control the OCT device 5 to record an intraoperative OCT image and may control the visualization system to display a representation of the recorded intraoperative OCT image. The controller may adjust a magnification of the representation of the intraoperative OCT image and/or a magnification of the representation of the preoperative OCT image so that the magnifications of the representation of the intraoperative OCT image and the magnification of the representation of the preoperative OCT image are equal.

Abstract: A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Abstract: An ophthalmic surgical microscope can include a movable optical element positioned in an optical pathway of light reflected from a surgical field. The movable optical element can be configured to oscillate in a direction along the optical pathway. The microscope can include an actuator coupled to the movable optical element and configured to move in response to a control signal. The microscope can include a computing device in communication with the actuator and configured to generate the control signal to move the movable optical element. In some embodiments, the computing device is configured to generate the control signal to move the movable optical element with an oscillation frequency greater than the critical flicker fusion rate.

Abstract: A module for a visualization apparatus includes an imaging optic accommodated in a base body for generating a viewing image of an object region with an optical viewing beam path. The module includes a display unit for visualizing an image superimposed on the viewed image of the object region with orientation information. The module has an image acquisition unit having an image sensor for acquiring an image of the object region. The module contains a switching unit for selectively providing and blocking an optical beam path from the display to the image sensor. The switching unit, in a first switching state, provides the image of a geometric structure on the display onto the image sensor with the optical beam path and, in a further switching state blocks the optical beam path from a geometric structure on the display to the image sensor.
