ABSTRACT:
The present invention relates in general to ophthalmic implants, and in particular to a new and useful transcleral apparatus for the draining of aqueous humor from the anterior chamber of the eye. The implant comprises a transcleral conduit having an inlet opening at one end thereof for communicating with the anterior chamber of an eye, and an outlet opening at an opposite end of the conduit for draining fluid from the anterior chamber. An elongated subconjunctival channel is connected to the conduit and has an inlet opening at one end of the channel for communicating with the outlet opening of the conduit, the channel having an outlet opening at an opposite end thereof for discharging fluid from the conduit, subconjunctivally over the sclera of the eye. A one-way flow resisting valve is provided in the conduit for allowing a flow of fluid to pass under resistance and in only one direction from the inlet to the outlet of the conduit, whereby pressure in the anterior chamber is relieved while avoiding excessive outflow of fluid from the anterior chamber.
