Abstract
An ocular adaptive lens prosthesis apparatus is provided. In some implementations the apparatus includes a tunable liquid crystal lens encapsulated in the ocular prosthesis with control electronics and a power source. The tunable liquid crystal lens is driven in response to a convergence signal to provide accommodation. In some embodiments the tunable liquid crystal device corrects other visual shortcomings of the natural eye. The ocular prosthesis has a remote programmable tunable liquid crystal lens controller configured to recalibrate the tunable liquid crystal lens to compensate for dynamic adaptation of the eye over time. A coil is employed to transmit a convergence signal between a pair of ocular prostheses in a dual eye vision correction system.
