First Claim
1. A valve system for use within an ophthalmic device, the valve system comprising:
- an adjustable valve having;
a housing defining a cavity; and
a movable diaphragm bounding at least one side of the cavity;
a fluid reservoir in fluid communication with the cavity of the adjustable valve;
a first check valve positioned between the fluid reservoir and the cavity of the adjustable valve along a first fluid passageway, the first check valve preventing fluid flow from the fluid reservoir to the cavity of the adjustable valve; and
a second check valve positioned between the fluid reservoir and the cavity of the adjustable valve along a second fluid passageway, the second check valve preventing fluid flow from the cavity of the adjustable valve to the fluid reservoir.

Abstract
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.
