Intraocular Pressure Sensor with External Pressure Compensation
First Claim
Patent Images
1. An intraocular pressure sensor system comprising:
- a first pressure sensor located in fluid communication with an anterior chamber of an eye; and
a remote pressure sensor located remotely from the first pressure sensor such that the remote pressure sensor measures or approximates atmospheric pressurewherein a difference between readings from the first pressure sensor and the remote pressure sensor approximates intraocular pressure.

Abstract
An intraocular pressure sensor system has a first pressure sensor located in an anterior chamber of an eye and a remote pressure sensor located remotely from the first pressure sensor. The remote pressure sensor measures or approximates atmospheric pressure. A difference between readings from the first pressure sensor and the remote pressure sensor approximates intraocular pressure.
