OPHTHALMIC LASER SYSTEMS WITH Z-DIRECTION MULTI-FOCAL OPTICS

Abstract:

In certain embodiments, an ophthalmic laser system comprises a laser source, multi-focal optics, scanners, delivery optics, and a computer. The laser source generates a laser beam of ultrashort laser pulses. The multi-focal optics multiplex the laser beam to yield focus spots in a target along a propagation axis of the laser beam. The scanners direct the laser beam in x, y, and z directions. The delivery optics focus the laser beam within the target to form the focus spots in the target along the propagation axis of the laser beam. The computer instructs the scanners and the delivery optics to direct and to focus the focus spots at the target according to a scan pattern.
