Abstract:
A cam-guided trephine for selectively cutting a portion of an eye provides a first, vertically disposed blade to provide an annular cut of essentially any practical shape, diameter and depth, while concurrently allowing a second, angled blade, to simultaneously provide a circular cut of substantially any practical angle, diameter, and depth. Each of the blades may be individually controlled by the surgeon, alternately and progressively lowered onto the eye during series of rotations.
