Apparatus and method for treating glaucoma
View Patent ↗Surgical methods and related medical devices for treating glaucoma are shown. The method includes trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a seton implant. The seton implant is used to prevent a healing process known as filling in, which has a tendency to close surgically created openings in the trabecular meshwork. The surgical method and novel implant are addressed to the trabecular meshwork, which is a major site of resistance to outflow in glaucoma. In addition to bypassing the diseased trabecular meshwork at the level of the trabecular meshwork, existing outflow pathways are also used or restored. The seton implant is positioned through the trabecular meshwork so that an inlet end of the seton implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
1. A device for treating glaucoma, comprising:
an ocular implant of biocompatible material sized and shaped to facilitate the transport of aqueous humor from the anterior chamber of the eye to and within Schlemm's canal, said implant comprising first and second lumens, each of which bypasses the trabecular meshwork and terminates in Schlemm's canal, so as to receive aqueous humor from the anterior chamber and transport said aqueous humor into Schlemm's canal.
