Abstract
A surgical method is provided for diverting aqueous humor from the anterior chamber of the eye. A surgical tool is provided having a hollow support member that supports a portion of an aqueous humor drainage device. The device has an elongate duct structure and preferably at least one fixation member that extends therefrom. The distal end of the hollow support member is inserted into the anterior chamber of the eye through an opening passing through the sclera. The aqueous humor drainage device is deployed from the hollow support member for placement into the eye. In one embodiment, the fixation member is realized by a tab that is spaced apart from the two ends of the elongate duct structure. In another embodiment, the fixation member is realized by a pair of tines that extend in traverse directions relative to the central axis of the elongate duct structure.
