Abstract
The invention concerns a system of measuring ocular pressure, consisting of at least one implant (30) including a pressure sensor (33) and an electronic circuit (32), implanted in the cornea of an eye and an antenna (31) connected to the said circuit and implanted in the sub-conjunctival space; and a unit (50) for processing the representative values of the pressure, received by a radio-frequency link from the said electronic circuit (30).
Claims15
A system for monitoring an eye pressure, comprising:
- (1) an implant comprising:
- (a) a pressure sensor configured to be implanted in between an internal surface and an external surface of a cornea of an eye, wherein the pressure sensor comprises a first pressure sensor surface and a second pressure sensor surface, wherein an electrically neutral liquid is between the first surface and the second surface, wherein the pressure sensor is configured to sense an intraocular pressure that is transmitted to the internal surface of the cornea with the first pressure sensor surface and sense an atmospheric pressure that is transmitted to the external surface of the cornea with the second pressure sensor surface, and wherein the pressure sensor is configured to determine the eye pressure which is equal to a difference between the intraocular pressure that is transmitted to the internal surface of the cornea and the atmospheric pressure that is transmitted to the external surface of the cornea;
- and
- (b) a first antenna operatively connected to the pressure sensor and configured to be implanted in a sub-conjunctival space of the eye and to transmit a signal that indicates the eye pressure;
- and
- (2) a unit comprising a second antenna and a processor, wherein the second antenna is configured to receive the signal, and wherein the processor is configured to process the signal.
