Abstract: A method for performing endolaser microsurgery on ocular and like tissues utilizing a laser delivery system and an intraocular probe for delivering the laser energy to the tissues comprising the steps of forming an incision in the conjunctiva surrounding the sclera, introducing the probe through the incision, moving the probe anteriorly beneath the conjunctiva to a site remote from the initial incision, and ablating by laser a drainage fistula through the sclera for relieving intraocular pressure.

Abstract: An apparatus for performing controlled tissue ablation in endolaser microsurgery is disclosed, the apparatus including a laser delivery system coupled to a probe capable of transmitting the laser power through a suitable medium such as sapphire. The probe may include a central canal for aspiration and irrigation and delivers a cross-sectionally homogeneous power distribution. The apparatus is designed to control the ablation depth and to limit the zone of thermal damage in the remaining tissue.

Abstract: A method and apparatus for performing endolaser microsurgery is disclosed, the apparatus including a laser delivery system coupled to a probe capable of transmitting the laser energy through a suitable medium such as sapphire. The probe includes a coaxial canal for aspiration of ablated tissue and/or fluids. The method involves steps of ablating tissue by laser and aspirating the ablated tissue and/or fluids, the method being useful for sclerostomy, vitrectomy and as a substitute for ultrasonic phacoemulsification among others.

Abstract: A cornea laser-cutting apparatus adapted for use in cutting out a cornea of patient's or donor's eye in full thickness cornea transplanting surgery or keratoplasty. The cornea laser-cutting apparatus comprises an HF or Er-YAG laser source and a projection optical system for converging laser beams radiated from the laser source in a ring-like shape on the cornea, and includes an axicon lens or mirror movably mounted for varying the size of the ring-like shape.
