A multi-optic accommodating intraocular lens (A-IOL) (40) for implantation in a capsular bag of an eye having an optical axis, includes a posterior component (44), an anterior component (42) that is translatable relative to the posterior component along an optical axis of the A-IOL, and a biasing element (46) that joins at least a portion of the anterior component and at least a portion of the posterior component. The A-IOL is quantitatively-characterized by an axial compression characteristic such as a spring constant or an axial restoring force. The axial compression characteristic is capable of keeping the components sufficiently vaulted apart for enabling near vision yet weak enough to allow the eye's accommodative mechanism to pull the optics close together for distance vision. |
