ABSTRACT:
An intraocular lens that provides accommodation in direct response to contraction and relaxation of the ciliary body. The lens includes a first component having fixed refractive power and a second component having varying refractive power, the components being relatively movable towards each other as the ciliary body contracts to increase the total refractive power of the lens.
