WINTER PARK, Fla., Feb. 5 -- LaserSight Inc. has been issued US Patent No. 6,334,683, Eye Illumination System and Method. The patent covers a system for providing illumination to an eye during laser refractive surgery that is needed for an eye tracking system.
Eye tracking systems follow movements of the patient's eye during laser vision correction treatments and send correcting signals to the scanning system in order to maintain the orientation and alignment of the laser beam with the visual or optical axis of the treated eye.
This is the third US patent issued to LaserSight in the field of eye illumination.
