electro-active IOLs use a proprietary combination of liquid-crystal chemistry, electricity, and integrated-circuitry to create smart optics, which will provide patients with the ability to see more naturally and clearly over the full range of vision. The technology includes an electro-active switchable element that automatically adjusts focusing power electronically, in milliseconds, to maintain constant in-focus vision for various working needs and/or light environments. The lens is controlled by a micro-sized power-cell with an expected 50+ year rechargeable cycle life.
