Abstract:
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 lens contains a pair of generally T-shaped haptics oriented along a vertical meridian of the capsular bag and having a generally rectangular slot within the top portion of the “T”. The first lens further having a plurality of elongated haptics oriented along a horizontal meridian of the capsular bag. The second lens is located anteriorly to the first lens outside of the capsular bag and is of a positive power. The peripheral edge of the second lens contains a pair of encircling haptics having a notched tab sized and shape to fit within the slots in the haptics on the first lens to lock the second lens onto the first lens. Hinge structures on the encircling haptics allow the second lens to move relative to the first lens along the optical axis of the lens system in reaction to movement of the ciliary muscle.
