An intraocular pressure sensor system has a first pressure sensor located in an anterior chamber of an eye and a remote pressure sensor located remotely from the first pressure sensor. The remote pressure sensor measures or approximates atmospheric pressure. A difference between readings from the first pressure sensor and the remote pressure sensor approximates intraocular pressure.

Intraocular pressure sensor with external pressure compensation

Glaucoma drainage devices including vario-stable valves and associated systems and methods are disclosed. A glaucoma drainage device includes a drainage lumen and a valve system coupled to the drainage lumen to control the flow of fluid through the drainage lumen. The valve system includes an adjustable valve with a diaphragm that is in communication with the drainage lumen and is movable to occupy varying amounts of the drainage lumen. In some embodiments, the valve system is maintained in a desired position without the use of power such that power is only needed when changing a position of the adjustable valve.

An intraocular pressure 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 includes a drainage tube and a valve system arranged to control drainage flow between the anterior chamber and the drainage site, the valve system being configured to control fluid flow using an electrolysis process and closed loop feedback from pressure sensors able to determine: flow rate, IOP, bleb pressure, and internal valve pressure.

Bubble-driven IOP control system

An IOP control system for implantation in an eye of a patient is disclosed. The IOP control system includes a drainage tube configured to convey aqueous humor from an anterior chamber of an eye and includes a pressure-driven valve system in fluid communication with the drainage tube and configured to control flow rates of the aqueous humor. The valve system includes a plurality of pressure-driven valves arranged to operate in cooperation with each other. The IOP control system may include an electronic pump system to further regulate flow.
