Intraocular device with wirelessly coupled auxiliary electronics
Techniques and mechanisms for the wireless transmission of power or control signals between two components of an implantable ophthalmic system are disclosed herein. An example device includes an accommodating intraocular lens (aIOL) and separate auxiliary electronics, both enclosed in biocompatible materials. The aIOL includes a dynamic optic, control logic, a battery and an antenna. The auxiliary electronics include an antenna, an energy storage cell, and a sensor. The auxiliary electronics may be wirelessly coupled to the aIOL for the wireless transmission of power or control signals.
1. An ophthalmic system comprising:
an accommodating intraocular lens (aIOL) including:
a first enclosure adapted for implantation into an eye;
a first antenna;
a dynamic optic disposed in or on the first enclosure and adapted to assist the eye with accommodation;
first control circuitry disposed within the first enclosure and coupled to the first antenna and the dynamic optic to adjust an optical power of the dynamic optic based upon a control signal received via the first antenna; and
a first power supply disposed within the first enclosure and coupled to the first control circuitry to power operation of the first control circuitry and the dynamic optic; and
auxiliary electronics including:
a second enclosure discrete and physically separate from the first enclosure;
a second antenna;
an accommodation sensor disposed in the second enclosure and adapted to sense an attempted accommodation of the eye;
second control circuitry disposed within the second enclosure and coupled to the accommodation sensor and the second antenna, the second control circuitry adapted to generate the control signal indicative of the attempted accommodation and send the control signal to the aIOL via the second antenna; and
a second power supply disposed within the second enclosure and coupled to the second control circuitry to power operation of the second control circuitry and the accommodation sensor,
wherein the first enclosure comprises a first biocompatible enclosure sized and configured for implantation into one of an anterior chamber, a posterior chamber, a sulcus, or a capsular bag, and wherein the second enclosure comprises a second biocompatible enclosure sized and configured for implantation inside the eye or anchoring to the eye,
wherein the auxiliary electronics are adapted to wirelessly couple to the aIOL for wireless transmission of information indicative of the attempted accommodation of the eye, and
wherein at least one of the first enclosure or the second enclosure includes components adapted for inductive power transfer.
2. The ophthalmic system of claim 1 , wherein the accommodation sensor is adapted to monitor a ciliary muscle of the eye or movement of a capsular bag of the eye.
3. The ophthalmic system of claim 1 , wherein the first and second antennas and the first and second control circuitries are further adapted to provide inductive charging of the first power supply from the second power supply.
4. The ophthalmic system of claim 1 , further comprising an external charger comprising an energy transmitting antenna adapted to wirelessly transmit electrical energy to the auxiliary electronics to charge the second power supply.
5. The ophthalmic system of claim 1 , wherein the second antenna comprises a circular-shaped, helical coil antennae.
6. The ophthalmic system of claim 1 , wherein the first power supply comprises a battery or a capacitor.
7. An ophthalmic system comprising:
an intraocular lens enclosed in a first biocompatible enclosure and including a dynamic optic, a first antenna, and a first power supply adapted for powering the dynamic optic to assist an eye with accommodation based upon a control signal received via the first antenna that is indicative of an attempted accommodation by the eye; and
auxiliary electronics enclosed in a second biocompatible enclosure, discrete and physically separate from the first biocompatible enclosure of the intraocular lens, wherein the second biocompatible enclosure is sized and adapted for implantation in or anchoring to the eye, the auxiliary electronics including a second antenna and a second power supply, wherein the auxiliary electronics include an accommodation sensor adapted to detect the attempted accommodation of the eye, wherein the auxiliary electronics are adapted to wirelessly couple to the intraocular lens and convey the control signal indicative of the attempted accommodation to the intraocular lens,
wherein the first biocompatible enclosure is sized and configured for implantation into one of an anterior chamber, a posterior chamber, a sulcus, or a capsular bag, and
wherein at least one of the first biocompatible enclosure or the second biocompatible enclosure includes components adapted for inductive power transfer.
8. The ophthalmic system of claim 7 , wherein the accommodation sensor is adapted to monitor a ciliary muscle of the eye or movement of a capsular bag of the eye when detecting the attempted accommodation of the eye.
9. The ophthalmic system of claim 7 , wherein the first and second antennas are adapted to provide inductive charging of the first power supply in the intraocular lens from the second power supply in the auxiliary electronics.
10. The ophthalmic system of claim 7 , wherein the second biocompatible enclosure is adapted for anchoring to a sclera of the eye.
11. The ophthalmic system of claim 7 , wherein the first power supply comprises one of a battery or a capacitor.
12. The ophthalmic system of claim 7 , wherein the dynamic optic comprises one of a liquid crystal lens or an electrowetting lens.
