Abstract
An implantable intraocular pressure sensor system has a sealed geometric shape with an internal pressure at a first value. A strain gauge wire is embedded in a surface of the sealed geometric shape. When the surface is deflected by intraocular pressure, a measured resistance of the strain gauge wire indicates the intraocular pressure. The system also has a processor coupled to a power source and memory. The processor is configured to read the measured resistance and write values corresponding to intraocular pressure to the memory.
