A two-optic accommodative lens system. The first lens has a negative power and
is located posteriorly against the posterior capsule. The periphery of the first
optic contains a pair of clasps. The second optic is located anteriorly to the
first optic and is of a positive power. The peripheral edge of the second optic
contains a pair of locking arms that fit into the clasps contained on the periphery
of the first optic to lock the second optic onto the first optic, but allow for
rotation of the arms within the clasps. Hinge structures on the locking arms 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.
