MULTI-PIECE ACCOMMODATING INTRAOCULAR LENSES AND METHODS FOR MAKING AND USING SAME
20220160496 · 2022-05-26 ·

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.
