Abstract
Abstract A system for illuminating an eye useful for tracking movement of an eye during vision correction treatments includes a generally arcuate main body having. The main body is constructed and arranged to be mounted in spaced relation to an eye to be tracked. An infrared light source is carried by the main body on at least a significant portion of its inner circumferential surface to direct infrared light toward the eye being treated at an angle from about 20 to 45 degrees with respect to an iris base plane of the eye being tracked.
