1. An implantable ophthalmic device to be implanted in an eye of a subject, the implantable ophthalmic device comprising:
- a bi-stable electro-active element to provide a first optical power in a first state and a second optical power in a second state;
a controller, operably coupled to the bi-stable electro-active element, to apply electrical power to the bi-stable electro-active element so as to switch the bi-stable electro-active element between the first state and the second state and to remove the electrical power from the bi-stable electro-active element after switching the bi-stable electro-active element between the first state and the second state; and
a conductive coil, in electrical communication with the controller, to receive the electrical power via wireless charging and to provide the electrical power to the controller.

9. A method of adjusting an implantable ophthalmic device comprising a bi-stable electro-active element, implanted in an eye, that provides a first optical power in a first state and a second optical power in a second state, the method comprising:
-
receiving electrical power at a conductive coil in the implantable ophthalmic device via wireless charging; applying the electrical power to the bi-stable electro-active element so as to switch the bi-stable electro-active element from the first state and the second state; and removing the electrical power from the bi-stable electro-active element after switching the bi-stable electro-active element from the first state and the second state. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An implantable ophthalmic device to be implanted in an eye of a subject, the implantable ophthalmic device comprising:
-
a static optical element to provide a fixed optical power; a bi-stable electro-active element, in optical communication with the static optical element, to provide a variable optical power that at least partially corrects for a higher-order aberration in the eye and/or a change in the subject'"'"'s vision; a controller, operably coupled to the electro-active element, to apply electrical power to the bi-stable electro-active element in response to a control signal so as to change the variable optical power of the bi-stable electro-active element and to remove the electrical power from the bi-stable electro-active element after changing the variable optical power of the bi-stable electro-active element; and a wireless receiver, operably coupled to the controller, to receive the control signal and at least a portion of the electrical power applied to the bi-stable electro-active element from a tuning apparatus external to the eye. - View Dependent Claims (17)
