New Type of Laser for Providing High-Resolution 3-D Images of the Retina

In efforts that may improve diagnoses of many eye diseases, researchers will introduce a new type of laser for providing high-resolution 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain.
