Abstract: A device drains aqueous humor from an eye. The device includes an inlet conduit positioned at least partially within an anterior chamber. The device includes a housing coupled to the inlet conduit. The housing includes a cavity in fluid communication with the inlet conduit. The inlet conduit includes an inlet passageway allowing aqueous humor to flow from the anterior chamber to the cavity. The device includes an outlet conduit coupled to the housing at a proximal end and in fluid communication with the cavity. The outlet conduit includes an outlet passageway allowing the aqueous humor to flow from the cavity at the proximal end to an external ocular surface via an outlet opening at the distal end. The device includes an anti-clogging element coupled to the outlet conduit and configured to prevent or remove an obstruction of the outlet conduit.
