Ophthalmic system including accommodating intraocular lens and remote component and related methods of use
Ophthalmic systems and methods of changing an optical power of an ophthalmic system are described. In an example, the ophthalmic system includes an accommodating intraocular device shaped to be implantable in an eye and an extraocular device separate from the accommodating intraocular device shaped to be removably mountable to a portion of the eye outside a bulb of the eye, such as an underlid portion of the eye. In an example, the method includes wirelessly transmitting power from a power source of an extraocular device removably mounted outside a bulb of an eye to an accommodating intraocular device implanted in the eye. In an example, the method includes sensing with an accommodation sensor biological accommodation signals of the eye; generating accommodation control signals representative of the biological accommodation signals; and driving an accommodation actuator disposed in the accommodating intraocular device based on the accommodation control signals to change an optical power of the ophthalmic system.
1. An ophthalmic system comprising:
an accommodating intraocular device shaped to be implantable in an eye, the accommodating intraocular device comprising:
a wireless receiver; and
an accommodation actuator configured to receive power from the wireless receiver and to change an optical power of the accommodating intraocular device; and
a remote device separate from the accommodating intraocular device and shaped to be removably mountable to portion of the eye disposed outside of a bulb of the eye, the remote device comprising:
a power source; and
a wireless transmitter operatively coupled to the power source and configured to wirelessly transmit power from the power source to the wireless receiver of the accommodating intraocular device,
wherein the remote device is semi-toroidally shaped to conformably contact and be removably mounted to a portion of the eye outside a fibrous tunic of the eye, and
wherein the remote device is shaped to be implanted under conjunctiva of the eye and contact a portion of sclera of the eye when the remote device is implanted under the conjunctiva.
2. The ophthalmic system of claim 1 , wherein the wireless transmitter encircles a periphery of a housing of the remote device.
3. The ophthalmic system of claim 1 , further comprising a sensor configured to detect biological accommodation signals of the eye and to generate accommodation control signals representative of the biological accommodation signals.
4. The ophthalmic system of claim 3 , wherein the accommodating intraocular device further comprises an intraocular controller operatively coupled to the wireless receiver, the sensor, and the accommodation actuator, the intraocular controller including logic that when executed by the intraocular controller causes the ophthalmic system to perform operations including:
driving the accommodation actuator to change the optical power of the accommodating intraocular device based on the accommodation control signals.
5. The ophthalmic system of claim 3 , wherein the sensor is disposed on the remote device.
6. The ophthalmic system of claim 5 , wherein the remote device further comprises a controller operatively coupled to the sensor, the power source, and the wireless transmitter and including logic that when executed by the controller causes the ophthalmic system to perform operations including:
transmitting, with the wireless transmitter, the accommodation control signals for receipt by the wireless receiver.
7. The ophthalmic system of claim 3 , wherein the accommodation control signals include a signal based on a position of ciliary muscles of the eye.
8. The ophthalmic system of claim 3 , wherein the accommodation control signals include a signal based on electrical activity of ciliary muscles of the eye.
9. The ophthalmic system of claim 1 , wherein the accommodating intraocular device further comprises an intraocular power source configured to receive power from the wireless receiver and to provide electrical power to the accommodation actuator.
10. The ophthalmic system of claim 9 , wherein the intraocular power source comprises one or more capacitors.
