Title: Photoablative laser eye-treatment method

Abstract: Transocular and periocular laser delivery system for treatment of eye diseases wherein a fiberoptic element is passed through a perforation made either by paracentesis of eyeball encapsulating tissue (i.e.--cornea, sclera) or by the fiberoptic element itself so that the fiber actually penetrates into a chamber therein. The penetrating fiber end is then juxtaposed to the tissue to be treated while the external fiberoptic end is coupled either to an excimer laser emitting ultraviolet radiation (in the range of 193 to 351 nanometers) or to certain lasers emitting infrared radiation, the radiated pulses therefrom being directed through the transocularly-positioned fiber to be absorbed by chromophores in the target tissue (cataractous lens, trabecular meshwork, vitreous membranes, tear duct occlusion) where removal by photoablation is effected. Photoablation by way of the fiberoptic element creates a portal for filtration of aqueous fluid in the case of glaucoma or allows removal of cataractous lens tissue, vitreous hemorrhage or membranes or other tissue occluding tear duct passages in a manner promoting controlled healing, minimizing inflammation and scarring.
