Abstract:
1. An implantable intraocular pressure sensor system comprising: a sealed geometric shape with an internal pressure at a first value, the sealed geometric shape having a first light permitting surface, a second flexible surface, and a third surface; first and second photocells located in the sealed geometric shape at the third surface; and a light shield coupled to and extending from the second flexible surface, the light shield located in the sealed geometric shape between the first light permitting surface and the third surface; wherein when the second flexible surface is deflected, the light shield partially blocks light that travels through the first light permitting surface to the first photocell but does not block light that travels through the first light permitting surface to the second photocell such that an amount of light detected by the first photocell differs from an amount of light detected by the second photocell, the difference between the amount of light detected by the first photocell and the amount of light detected by the second photocell indicating an intraocular pressure condition.
