Abstract
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.
Claims22
An intraocular lens assembly comprising:
- a lens body having an optical axis, a periphery, and an aspheric optical surface configured to provide an optical power that continuously and progressively increases from the optical axis to the periphery;
- and
- a movement assembly positioned relative to the lens body and configured to cooperate with the lens body to effect accommodating movement of the lens body in the eye.
An intraocular lens assembly comprising:
- a lens body having an optical axis, a periphery, an anterior surface and a posterior surface, at least one of the surfaces comprising a spherical central portion and a single aspheric optical zone configured to provide an optical power that continuously and progressively increases from a periphery of the central portion to the periphery of the lens body, the aspheric optical zone having a diameter in the range of about 4.0 to about 7.0 mm;
- and
- a movement assembly positioned relative to the lens body and configured to cooperate with at least one of the ciliary muscle of the mammalian eye, the zonules of the mammalian eye and the vitreous pressure in the eye to effect accommodating movement of the lens body in the eye.
