Abstract:
1. An IOP control system for implantation in an eye of a patient to provide drainage from an anterior chamber of the eye to a drainage location at the eye, comprising: a valve system having an open flow position and a closed zero flow position, the open flow position permitting fluid flow through the valve system, the closed zero flow position substantially preventing fluid flow through the valve system, the valve system comprising: a sensor system comprising a first sensor arranged to detect a first pressure representative of a real-time parameter of the eye; and a controller arranged to receive data from the sensor system and compare data representing the detected pressure to a preestablished upper pressure threshold and a preestablished lower pressure threshold to determine whether to change the state of the valve system in a bimodal fashion from one of an open flow position and the closed zero flow position to the other of the open flow position and the closed zero flow position.
