Examples relate to apparatuses, methods and computer programs for controlling a microscope system, and to a corresponding microscope system. An apparatus for controlling a microscope system comprises an interface for communicating with a camera module. The camera module is suitable for providing camera image data of a head of a user of the microscope system. The apparatus comprises a processing module configured to obtain the camera image data from the camera module via the interface. The processing module is configured to process the camera image data to determine information on an angular orientation of the head of the user relative to a display of the microscope system. The processing module is configured to provide a control signal for a robotic adjustment system of the microscope system based on the information on the angular orientation of the head of the user.

A medical holding apparatus includes: a support including a plurality of arms, and a plurality of joints configured to connect the plurality of arms, the support being configured to support an imaging unit at a distal end thereof; a load applying mechanism arranged in at least one of the joints and configured to apply a resistance load against operation of the at least one of the joints to the support; and a processor comprising hardware, the processor being configured to: set torque to be applied by the load applying mechanism based on an operating state of the imaging unit; and apply a load corresponding to the set torque to the load applying mechanism when a rotation inhibit state of each of the arms of the support is released.

Provided is an image processing device including a matching unit that performs matching processing between a predetermined pattern on a surface of a 3D model of a biological tissue including an operating site generated on the basis of a preoperative diagnosis image and a predetermined pattern on a surface of the biological tissue included in a captured image during surgery, a shift amount estimation unit that estimates an amount of deformation from a preoperative state of the biological tissue on the basis of a result of the matching processing and information regarding a three-dimensional position of a photographing region which is a region photographed during surgery on the surface of the biological tissue, and a 3D model update unit that updates the 3D model generated before surgery on the basis of the estimated amount of deformation of the biological tissue.

A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.
