Abstract
An intraocular adaptive lens prosthesis apparatus is provided. In some implementations the apparatus includes a tunable liquid crystal lens encapsulated in the intraocular prosthesis with control electronics and a power source. In other implementations the apparatus includes a tunable liquid crystal lens encapsulated in the intraocular prosthesis with a control signal receiver while an external control electronics package transmits the control signal. The tunable liquid crystal lens is driven in response to a stimulus signal to provide accommodation. In some embodiments the tunable liquid crystal device corrects other visual shortcomings of the natural eye.
