Abstract:
1. A system for displaying to a user an aligned first and second image of an eye comprising: a first imaging device for collecting a first image of an eye; a second imaging device for collecting a second image of the eye; a processor having resident thereon a software package comprising code segments adapted for: determining a limbus location on the first and the second eye image; aligning the limbus location of the first and the second eye images in two dimensions; determining a location of a second eye feature on the first and the second eye image; relatively rotating one of the first and the second eye image; performing a correlation on the first and the second eye image at a plurality of relative rotational positions using the second eye feature location; and from the correlation, identifying an optimal first and second image alignment; and a display device in signal communication with the processor adapted to display to a user the optimal first and second image alignment.
