<p>A selectable IOP valve (60) for implantation in an eye of a patient controls IOP and/or bleb pressure. The valve includes a drainage tube configured to convey aqueous from an anterior chamber of an eye- and includes a selectable flow control valve in fluid communication with the drainage tube and configured to control flow rates of the aqueous. The valve system includes a plurality of flow control pathways (602a-c) arranged to operate in parallel with each other, each of the flow control pathways being in communication with an entry port (604) to the valve system. A flow control mechanism (606, 608, 610) controls aqueous flow through the pathways. Methods and systems are also disclosed.</p> |
