Abstract

An optical accommodating system for an eye includes a sensor assembly and an adjustable optic assembly. The sensor assembly includes a sensor configured to sense a movement of the ciliary muscle and produce a signal, an electronic processor, a transmitter and a power source. The adjustable optic assembly is configured to be either implanted within or on the eye, or configured to be disposed adjacent to or near the eye. The adjustable optic assembly includes a switchable optical lens assembly configured to change its optical power between a first state and a second state, a receiver configured to receive the transferable signal from the transmitter of the sensor assembly, a second electronic processor connected to the receiver which directs the switchable optical lens assembly to change its optical power between the first state and second state, and a second power source connected to the second electronic processor.
