Infrared communication with an opthalmic device
View Patent ↗Techniques and mechanisms for participating in a wireless communication with an implantable ophthalmic device. In an embodiment, an exterior of an ophthalmic device includes a biocompatible surface of an enclosure having control circuitry disposed therein. With the control circuitry, the ophthalmic device aids in sensing a condition at an eye or assists vision with the eye. In another embodiment, wireless communication circuitry is disposed in or on the enclosure, the wireless communication circuitry to participate in a communication of a wireless signal that is in an infrared wavelength range of the electromagnetic spectrum. Electrical signaling between the control circuitry and the wireless communication circuitry is based on the wireless signal. In another embodiment, the wireless signal is based on electrical signaling between the control circuitry and the wireless communication circuitry.
1. An ophthalmic device for implantation in an eye, the ophthalmic device comprising:
an enclosure formed of a biocompatible material;
control circuitry disposed in the enclosure and configured to sense a condition at the eye or to assist vision of the eye;
wireless communication circuitry disposed in or on the enclosure, the wireless communication circuitry electrically coupled to the control circuitry, wherein the wireless communication circuitry includes:
an optical receiver oriented to face a retina of the eye to detect first wireless signals from an external device outside of the eye after reflection off of the retina of the eye when the ophthalmic device is implanted into the eye, wherein the optical receiver is configured to detect the first wireless signals in an infrared band; and
an optical transmitter oriented to face the retina of the eye when the ophthalmic device is implanted into the eye to emit second wireless signals for communicating with the external device outside of the eye via reflecting the second wireless signals off of the retina; and
a dynamic optic positioned to assist vision of the eye when the ophthalmic device is implanted into the eye, wherein the dynamic optic is positioned to pass the first wireless signals incident into the eye prior to reflection off of the retina and pass the second wireless signals out of the eye after reflection off of the retina.
2. The ophthalmic device of claim 1 , wherein the control circuitry is configured to selectively turn a functionality of the ophthalmic device on or off in response to the first wireless signals.
3. The ophthalmic device of claim 1 , wherein the infrared band is between 700 nanometers (nm) and 2000 nm.
4. The ophthalmic device of claim 1 , further comprising a pressure sensor disposed in or on the enclosure.
5. The ophthalmic device of claim 1 , wherein the communication circuitry is to further exchange wireless communications between the ophthalmic device and another device, the wireless communications having a wavelength in a radio band.
6. The ophthalmic device of claim 1 , wherein the ophthalmic device comprises an intraocular lens.
7. A system comprising:
a base communication station; and
an ophthalmic device for implantation in an eye, the ophthalmic device comprising:
an enclosure formed of a biocompatible material;
control circuitry disposed in the enclosure and configured to sense a condition at the eye or to assist vision of the eye;
wireless communication circuitry disposed in or on the enclosure, the wireless communication circuitry electrically coupled to the control circuitry, wherein the wireless communication circuitry includes:
an optical receiver oriented to face a retina of the eye to detect first wireless signals from the base communication station after reflection off of the retina of the eye when the ophthalmic device is implanted into the eye, wherein the optical receiver is configured to detect the first wireless signals in an infrared band; and
an optical transmitter oriented to face the retina when the ophthalmic device is implanted into the eye to emit second wireless signals for communicating with the base communication station located outside of the eye via reflecting the second wireless signals off of the retina; and
a dynamic optic positioned to assist vision of the eye when the ophthalmic device is implanted into the eye, wherein the dynamic optic is positioned to pass the first wireless signals incident into the eye prior to reflection off of the retina and pass the second wireless signals out of the eye after reflection off of the retina.
