An accommodating intraocular lens includes an optic portion, a haptic
portion. The optic portion of the lens includes an actuator that deflects
a lens element to alter the optical power of the lens responsive to
forces applied to the haptic portion of the lens by contraction of the
ciliary muscles and a secondary deflection mechanism. Movement of the
lens element by the actuator causes the lens element to deform and the
secondary deflection mechanism causes the lens to further deform.
