An accommodative intraocular lens is provided to replace a natural lens. The
intraocular
lens structure includes an optical portion and a haptic portion. The optical portion
includes a replacement lens while the haptic portion includes the structure that
holds the lens in position while keeping the anterior capsular sac taunt and annular
in shape. The haptic in the present invention stabilizes the annular structure
of the peripheral zone at the capsular sac's largest diameter and also stabilizes
the conical structure of the capsular sac as well. The haptic structure includes
a helical coil of increasing radius from the lens to the terminating annular ring
that thus forms a conical coil spring. Compression and relaxation of the coiled
(spring) haptics between the anterior and posterior capsule, during tightening
and relaxation of lens zonule and ciliary body, move the lens to anteriorly and
posteriorly and induces accommodation.
