ACCOMMODATING INTRAOCULAR LENS SYSTEM UTILIZING DIRECT FORCE TRANSFER FROM ZONULES AND METHOD OF USE
摘要
An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes a lens piston that alters the shape of a lens element of the lens to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion are transferred hydraulically to cause the lens to become more or less accommodated. The haptic portion is retained in a fixed unaccommodated state during an initial healing period following implantation to facilitate affixation of the haptic portion to the capsule.
