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.

Eye illumination system and method

An apparatus is provided for performing corneal refractive surgery by ablating a portion of a corneal surface of an eye. The apparatus includes a pulsed laser for producing a pulsed output beam of light. A scanning mechanism scans the output beam, and the output beam is operatively associated with the scanning mechanism such that the output beam may be scanned over a predetermined surface defined by a mathematically derived ablation layer boundary curve for each ablation layer. A controller is operatively associated with the scanning mechanism so as to deliver output beams to the predetermined surface such that center points of output beams may be disposed within the ablation layer boundary curve, on the ablation layer boundary curve, and outside but within a predetermined distance from a nearest point on the ablation layer boundary curve so as to integrate the edges of the ablation layer boundary curve to more closely correspond to the desired ablated shape.
