The novel aqueous humor drainage device for glaucoma consists of T-shaped pipe and draining disc connected together. The T-shaped pipe has an elastic transverse pipe with many homogeneously distributed humor inflowing holes in the aqueous humor contacting surface and a vertical pipe communicated perpendicularly with the transverse pipe and with back pressure controlling system. The draining disc has groove in the front part for the pressure controlling system, humor storing area in the back part, humor flow holes in the bottom and ridges in the center and the edge. The pressure controlling system is constituted in the extending part of the T-shaped pipe and inside the grooves of the draining disc. The aqueous humor drainage device makes the explant attached to the eyeball closely, has expanded filtering volume to reduce the stimulation to eyeball and peripheral tissue. It has good implanting operation performance, and can lower eye pressure and control eye pressure in normal range.
