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.
