Abstract
An implantable device used in treating glaucoma includes a movable plate shaped and sized to fit in a single quadrant of an eye to provide maximum surface area. A drainage tube is attached to the plate and has a distal end for insertion into the anterior chamber of the eye to drain fluid. A valve is disposed in the tube to control the fluid pressure within the eye and prevent hypotony. The plate is made of soft surgical grade polymeric material to prevent extrusion from the body.
