A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and laying against the posterior capsule. The periphery of the first optic contains a pair of generally T-shaped haptics having a generally rectangular slot within the top portion of the "T". The second optic is located anteriorly to the first optic outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a pair of encircling haptics having a notched tab sized and shape to fit within the slots in the haptics on the first optic to lock the second optic onto the first optic. Hinge structures on the encircling haptics allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle. |
