INTRA-OCULAR LENS SYSTEM HAVING TUNABLE ELECTRO-ACTIVE LENS ELEMENTS

摘要

An intraocular lens system comprises an intra-ocular lens, an electro-active lens element powered by an electric power source and optically communicating with the intraocular lens to provide variable power, and a piezoelectric element communicating with the power source for generating charges in response to eye ciliary body mechanical forces.
