Quantitative Evaluation of Red Reflex Between Nearly Collimated Beam and Focused-Beam Microscope Illumination Systems for Cataract Surgery

Video describes a technique to quantitatively evaluate and compare the red reflex intensity and range from a patient's eye using a nearly-collimated beam or focused beam illumination source found on ophthalmic microscopes used for cataract surgery.  A new application of video-imaging programs allowing measureable analyses of viewing quality is shown.
