Abstract: A unitary, pressure-regulating corneal implant device for use in controlling intraocular pressure of the cornea is disclosed, the implant having a conduit with a bore and a porous core material disposed in the bore for allowing egress of aqueous humor from the anterior chamber of the eye. The conduit is elongated for extending from the ocular surface of the eye substantially flush therewith through the corneal stroma, and into the anterior chamber.
