System, device, and method for determination of intraocular pressure

A system for determination of intraocular pressure, the system comprising:

• an intraocular pressure sensor including a substrate member, a spacer member, and a flexible membrane, the substrate member, the spacer member and the flexible membrane forming walls of a sealed cavity having no openings for fluid communication with a vacuum, the flexible membrane having an exterior surface and being configured to deform in response to intraocular pressure when the intraocular pressure sensor is implanted in an eye;
• a light source configured to illuminate the exterior surface of the flexible membrane with an incident light including one or more wavelengths of light;
• the flexible membrane configured to partially transmit and partially reflect the incident light, the substrate member configured to reflect the incident light that is partially transmitted back through the flexible membrane to create an interference pattern with the incident light that is partially reflected, the interference pattern consisting of bright and dark rings having a separation depending on a curvature of the flexible membrane;
• and
• an electronic imaging device configured to capture an image of the interference pattern.
