Abstract

An apparatus for monitoring intraocular pressure including an implantable intraocular lens and at least one sensor apparatus responsive to intraocular pressure being affixed to the lens.

Claims

1. An apparatus for monitoring intraocular pressure comprising an intraocular lens implantable within the eyeball and at least one sensor apparatus affixed to said implantable intraocular lens and implantable therewith within the eyeball, said sensor apparatus being responsive to intraocular pressure.

6. The apparatus of claim 1 wherein the lens further comprises an optic and at least 1 haptic and the sensor is affixed to a haptic of the lens.

7. The apparatus of claim 1 wherein the lens further comprises an optic and the sensor is affixed to the optic of the lens.

2. A system for monitoring intraocular pressure comprising:

an intraocular lens implantable within the eyeball and an intraocular pressure sensor affixed to said intraocular lens and implantable therewith within the eyeball, said intraocular pressure sensor being responsive to intraocular pressure, and

an extracorporeal device responsive to the intraocular pressure on the implantable intraocular pressure sensor.

3. The apparatus of claim 2 wherein said passive endoradiosonde comprises a resonant circuit whose resonant frequency is responsive to intraocular pressure.

4. The apparatus of claim 3 wherein said resonance circuit comprises a pair of parallel, coaxial, spaced apart archimedean spiral coils.

5. The apparatus of in claim 4 wherein each coil is located within a nonconducting cylinder and is attached to an interior surface of one of each of two nonconducting diaphragms which seal each end of the nonconducting cylinder.

8. A system for monitoring intraocular pressure comprising:

an implantable intraocular lens and an implantable intraocular pressure sensor affixed thereto responsive to intraocular pressure and

an extracorporeal device responsive to the intraocular pressure on the implantable intraocular pressure sensor.

9. The system of claim 8 wherein the implantable intraocular pressure sensor is a passive endoradiosonde.

10. The system of claim 9 wherein the extracorporeal device is a sweeping variable frequency grid-dip meter for determining the resonant frequency of the endoradiosonde.
