1. An eye illumination system comprising:
- a main body; and
a generally arcuate light source carried by said main body, said generally arcuate light source having an inner diameter greater than approximately 140 mm;
said main body being constructed and arranged to be mounted in spaced relation to an eye to be illuminated such that light from said generally arcuate light source is directed to a pupil of said eye at an angle greater than 20 degrees with respect to a plane tangential to an iris of said eye.

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.
