Intraocular Pressure Sensor
First Claim
Patent Images
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 and a second flexible surface;
a pair of photocells located in the sealed geometric shape; and
a light shield coupled to the second flexible surface;
wherein when the second flexible surface is deflected, a light measurement by the pair of photocells indicates an intraocular pressure condition.

Abstract
An implantable intraocular pressure sensor system has a sealed geometric shape with an internal pressure at a first value. The sealed geometric shape has a first light permitting surface and a second flexible surface. A pair of photocells is located in the sealed geometric shape. A light shield is coupled to the second flexible surface. When the second flexible surface is deflected, a light measurement by the pair of photocells indicates an intraocular pressure condition.

12. An implantable intraocular pressure sensor system comprising:
-
an IOP sensor comprising; a sealed geometric shape with an internal pressure at a first value, the sealed geometric shape having a first light permitting surface and a second flexible surface; a pair of photocells located in the sealed geometric shape; and a light shield coupled to the second flexible surface; wherein when the second flexible surface is deflected, a light measurement by the pair of photocells indicates an intraocular pressure condition; a processor; a power source coupled to the processor; and a memory coupled to the processor; wherein the processor is configured to read the measured resistance and write values corresponding to intraocular pressure to the memory. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
