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.
