Accommodating intraocular lens system with aberration-enhanced performance

An accommodating intraocular lens implantable in an eye having an optical axis, the lens comprising:

• an anterior portion having an anterior biasing element and an anterior viewing element, the anterior viewing element comprising an optic having refractive power;
• a posterior portion having a posterior viewing element;
• the anterior biasing element attached to a periphery of the anterior viewing element at substantially diametrically opposed first and second attachment locations;
• the periphery of the anterior viewing element being unattached to the anterior biasing element between the first and second attachment locations;
• the size of the first and second attachment locations being sufficiently small such that an optical axis of the anterior optic tilts and/or decenters relative to the optical axis of the eye during movement of the anterior optic relative to the posterior viewing element generally along the optical axis of the eye under force applied by the ciliary body.

An accommodating intraocular lens implantable in an eye, the lens comprising:

• an anterior portion having an anterior biasing element and an anterior optic having refractive power;
• and
• a posterior portion having a posterior biasing element and a posterior optic having refractive power;
• the anterior optic and the posterior optic being relatively moveable generally along an optical axis of the eye in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens, the anterior optic and the posterior optic each having an optical axis;
• the lens having an aberration-inducing force characteristic to allow aberration-inducing relative movement of the optical axes of the optics when the lens is in the eye to create or increase axial offset and/or angular orientation of the optical axes relative to each other thereby adding optical aberration to the lens which increases depth of focus of the lens.
