<p>An implantable passive intraocular pressure sensor (10) is disclosed. The sensor (10) Includes a sealed housing having a passage (20) therein. The passage (20) allows light (36A, 36B) to pass and reach the retina (38). The sensor's (10) housing has walls forming a sealed chamber. At least one wall of the housing is a movable wall configured for moving or deforming in response to changes in the pressure outside the sensor (10). The sensor (10) includes a passive electromagnetic resonant circuit (14). At least one portion of the circuit (14) is mechanically coupled to one or more of the movable or deformable walls of the housing, such that the resonance frequency of the resonant circuit (14) varies as a function of the pressure outside the sensor. The passage (20) within the housing may be open or, alternatively, one or more optical elements such as an intraocular lens or filters, or other optical elements may be disposed in the passage (20) to modify light (36A, 36B) passing through the passage (20). A system (28) for use with the implantable intraocular sensors (10) and methods for implanting the sensors (10) are disclosed.</p> |
