  • Patent number: 5558630
    Abstract: A tubular conduit style implant device for the regulation of intraocular pressure is described. The device is generally funnel shaped and enlarges from its forward end, for implanting in the anterior chamber of an eye, to its rearward end, for implanting in the sclera. The tubular body of the device includes laterally extending appendages adapted to stabilize the implant from rocking in position. In addition, the forward end of the device includes both a positioning ridge, to space the device from an inner surface of the eye, and an oppositely positioned retention flange to prevent migration of the implant from the anterior chamber. The rearward end of the device positioned within the sclera includes fluid passageways for controlling fluid outflow from the interior of the eye.
