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.

Warm white light illumination and digital image processing of digital images during microsurgery

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.
