Intraocular lenses include a lens body sized and adapted for placement
in a mammalian eye and having a plurality of different optical powers, and a movement
assembly joined to the lens body and adapted to cooperate with the mammalian eye
to effect accommodating movement of the lens body in the eye. The lens body has
an azonal, aspheric surface, with the correction power of the lens varying continuously
and progressively from the optical axis to the periphery of the lens. Such intraocular
lenses provide enhanced accommodation relative to the accommodation attainable
using a spheric, monofocal IOL adapted for accommodating movement or an aspheric
accommodating lens located in a substantially fixed position in an eye.
