    Abstract: This disclosure provides techniques and apparatuses for displaying stereoscopic video data of a target surgical site. An example ophthalmic imaging apparatus includes first and second stereoscopic lens sets configured to receive light from the target surgical site. In some embodiments, first stereoscopic lens set includes at least a first fixed focal length lens configured to magnify the received light according to a first fixed magnification level. In some embodiments, the second stereoscopic lens set includes at least a second fixed focal length lens configured to magnify the received light according to a second fixed magnification level different from the first fixed magnification level. The ophthalmic imaging apparatus also includes first and second pluralities of image sensors configured to receive the light and generate first and second image data. The first and second image data may be converted into first and second stereoscopic video data for display on a display monitor.

    Abstract: This disclosure provides techniques and apparatuses for displaying stereoscopic video data associated with different viewing angles of a target surgical site. An example ophthalmic imaging apparatus includes a first camera head mounted in a first orbital position above a target surgical site associated with an eye of a patient, wherein the first camera head includes at least one stereoscopic lens set providing a first viewing angle of the target surgical site. Additionally, the ophthalmic imaging apparatus includes at least a second camera head mounted in a second orbital position above the target surgical site, wherein the second camera head includes at least one additional stereoscopic lens set providing a second viewing angle of the target surgical site different from the first viewing angle of the target surgical site.

    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.
