ABSTRACT:
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.
