Claim:
1. An artificial intraocular lens of variable optical power comprising at least two optical elements of which at least one can be shifted relative to any other element in a direction extending perpendicular to an optical axis when in an eye, wherein the shape of the surface of at least two optical elements includes a saddle-shaped surface according to the formula t=A(xy wherein the optical elements, in combination, form a lens of which the optical power varies depending on the relative position of the optical elements, wherein each of the optical elements is affixed to an elastic haptic on one side thereof and to a non-elastic haptic on an opposite side thereof, wherein the elastic haptic affixed to each optical element is connected to one non-elastic haptic of another optical element through a connecting anchor, such that the lens comprises at least two separate connecting anchors, wherein a direction of relative shifting of the optical element is parallel to an imaginary line connecting the separate connecting anchors.
