1. An open accommodative, intraocular lens system operable to be positioned within the interior of an evacuated capsular bag of a human eye, said intraocular lens system comprising:

  • a first lens optic, operable to be positioned within an anterior portion of an evacuated capsular bag of a human eye, having a central optic axis;

    a second lens optic, operable to be positioned within a posterior portion of an evacuated capsular bag of a human eye, having a central optic axis coaxial with said central optic axis of said first lens optic, said second lens optic having a concave, spheric, anterior surface;

    a first flexible longitudinally arcuate haptic being arcuate in the direction of said central optic axis and having a first end and a second end, said first haptic extending between said first and second lens optics and directly connected at said first end to said first lens optic and directly connected at said second end to said second lens optic respectively; and

    at least a second flexible longitudinally arcuate haptic being arcuate in the direction of said central optic axis and having a first end and a second end, said second haptic extending between said first and second lens optics and directly connected at said first end to said first lens optic and directly connected at said second end to said second lens optic respectively, each longitudinally arcuate haptic operable when positioned in an evacuated capsular bag to extend in a generally elliptical curve in longitudinal cross-section and to follow the contour of an interior surface of the evacuated capsular bag said first and second lens optics operable to be supported in general visual axial alignment within an evacuated capsular bag by said first longitudinally arcuate haptic and said at least second longitudinally arcuate haptic abutting against and being supported by interior surfaces of the evacuated capsular bag and the ciliary muscles of a wearer of the intraocular lens system acting through Zonula connected to an exterior surface of the evacuated capsular bag being operable to pull on the evacuated capsular bag and the ciliary muscle and the arcuate haptics being operable to selectively vary the distance between said first lens optic and said second lens optic along the central optic axis of said first lens optic and said second lens optic and facilitate accommodated vision of a wearer of the intraocular lens system.
