摘要：
An accommodating intraocular lens (AIOL) for implantation within a capsularbag of a patient's eyecomprises first and second components coupled together to define an innerfluid chamber and an outerfluid reservoir. The inner region of the AIOL provides optical power with oneor more of the shapedfluid within the inner fluid chamber or the shape of the first or secondcomponents. The fluid reservoircomprises a bellows region with one or more folds of the bellows extendingcircumferentially around anoptical axis of the eye. The bellows engages the lens capsule, and a compliantfold region between theinner and outer bellows portions allows the profile of the AIOL to deflectwhen the eye accommodatesfor near vision. Fluid transfers between the inner fluid chamber and the outerfluid reservoir to provideoptical power changes when the eye accommodates.
