Abstract

This invention, a Purkinjenator™ optical system, is an eye-tracker and methodology for tracking Purkinje reflection images from a human eye in real-time, which allows for the XYZ position and tip/tilt of structures inside the eye to be determined in real-time. When used in combination with programmable groups of IR LED light sources, unique patterns of Purkinje reflections from internal surfaces (and corneal surfaces) can be identified. Thus, XYZ positioning and tip/tilt of internal structures can be accurately and rapidly determined. An Optical Coherence Tomography (OCT) optical system can be combined with the Purkinjenator™ optical system to provide Z-axis distance information.
