Accommodative Intraocular Lens
First Claim
1. A method for improving near vision of a non-dominant eye of a patient comprising the steps of implanting in the non-dominant eye of the patient an accommodating intraocular lens which has a flexible lens body having normally anterior and posterior sides and including a flexible solid optic, the optic having a central area of increased power of less than 1.0 diopter to enable an extended region of depth of field about the far point of a patient'"'"'s vision, the lens body having two or more extending portions from the optic such that the lens can move anteriorly with contraction of the cilary muscle of the eye, and the lens being sized to be implanted into the capsular bag of the eye such that contraction of the ciliary muscle causes the optic of the lens within the capsular bag behind the iris to move forward to toward the iris with its contraction.

Abstract
An accommodating intraocular lens where the optic is moveable relative to the outer ends of the extended portions. The lens comprises an optic made from a flexible material combined with extended portions that is capable of multiple flexions without breaking. The optic has a central area of increased power of less than 1.0 diopter aid near vision. A method is disclosed of implanting the present lens in the non-dominant eye of a patient.

3. Accommodating intraocular lenses for implantation in the eyes of a patient comprising two flexible lens bodies having normally anterior and posterior sides, each including a flexible solid optic,
the lens bodies each having two or more radially extending portions from each optic such that the optic of the lenses can move anteriorly with contraction of the ciliary muscles of the eye, one optic having a central area of increased power of less than 1.0 diopter on the anterior side of the optic, and each lens being sized to be implanted into a respective capsular bag of the eye such that contraction of the ciliary muscles causes the optics of the lenses within the capsular bags behind the iris to move forward toward the iris with muscle contraction.
