摘要：
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.
