ABSTRACT:
An intraocular lens including a PMMA intraocular lens implant, a second soft and pliable lens disposed thereover such as that of silicon, and electromechanical circuitry for regulating the distance between the soft silicon lens and the hard PMMA lens. The electromechanical circuitry can include a microsolar power cell, a microprocessor, a microfluid pump, a micro reservoir for fluid, and a micro DC storage cell. The electromechanical circuitry provides for adjustment of the focal point of the lens system for accommodation from distance to near vision.
