Abstract
A Light Adjustable Lens (LAL) Tracker comprises an Imaging System, for creating a LAL image by imaging a LAL implanted into an eye; and an Image Recognition System, coupled to the Imaging System, for determining a disk cross-correlator with the LAL image; determining an edge cross-correlator with the LAL image; and determining a LAL position by determining a combined cross-correlator from the disk cross-correlator and the edge cross-correlator. A Tracking-based Illumination Control System comprises the LAL Tracker for tracking a LAL implanted in an eye, including an Imaging System, and an Image Recognition System; and an Illumination Controller, coupled to the LAL Tracker, configured for determining a LAL misalignment factor, corresponding to a LAL misalignment that characterizes a misalignment of the LAL position with a LAL illumination pattern, and generating an illumination control signal in relation to the determined LAL misalignment factor.
