Abstract: A method for enhancing digital images during a microsurgery, e.g., an eye surgery, includes collecting digital images of target anatomy using a digital camera as the target anatomy is illuminated by warm white light. The method includes identifying, via a processor in communication with the digital camera, a predetermined stage of the microsurgery. Within the images, the processor digitally isolates a first pixel region, e.g., a pupil pixel region, from a second pixel region, e.g., an iris pixel region, and adjusts a characteristic of constituent pixels thereof. The method, possibly recorded as instructions in a computer-readable medium, may be used to enhance a red reflex at predetermined stages of an eye surgery. A system includes a lighting source for emitting warm white light having a color temperature of less than about 4000° K, the camera, and the processor.

Abstract: A stereoscopic imaging apparatus and platform are disclosed. An example stereoscopic imaging apparatus includes a main objective assembly and left and right lens sets defining respective parallel left and right optical paths from light that is received from the main objective assembly of a target surgical site. Each of the left and right lens sets includes a front lens, first and second zoom lenses configured to be movable along the optical path, and a lens barrel configured to receive the light from the second zoom lens. The example stereoscopic imaging apparatus also includes left and right image sensors configured to convert the light after passing through the lens barrel into image data that is indicative of the received light. The example stereoscopic visualization camera further includes a processor configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.

Abstract: A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-infrared light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.

Abstract: A robotic imaging apparatus is disclosed. A robotic imaging apparatus includes a robotic arm, a stereoscopic camera, and a sensor positioned between the robotic arm and the stereoscopic camera. The sensor transmits output data that is indicative of translational and rotational force imparted on the stereoscopic camera by an operator. The robotic imaging apparatus also includes a processor that is configured to determine a movement sequence for the robotic arm based on a current position of the robotic arm and the output data from the sensor and to cause at least one of the joints of the robotic arm to rotate based on the determined movement sequence via one or more motor control signals provided to the at least one joint. The rotation of the at least one joint provides power-assisted movement of the robotic arm based on the detected translational and rotational forces imparted by the operator.

Abstract: A method for enhancing digital images during an eye surgery includes producing warm white light via a lighting source by blocking blue and green wavelengths of light using an excitation filter. The method includes illuminating a pupil and iris of the eye with the warm white light during the eye surgery and collecting digital images of target anatomy using a digital camera. Within the images, a processor digitally isolates a pupil pixel region from an iris pixel region and adjusts a characteristic of constituent pixels of one of the regions. The method may be performed by executing instructions from a computer-readable storage medium to enhance a red reflex at predetermined stages of an eye surgery.
