Abstract

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 one or more folds of the bellows 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 when the eye accommodates.

Claims21

Dependent claims

An accommodating intraocular lens, comprising:

a first component including an inner portion and an outer portion;
a second component positioned posterior to the first component when the accommodating intraocular lens is implanted in an eye of a patient;
and
a circumferential wall extending between the first component and the second component;
and
a haptic extending outwardly from the circumferential wall, the haptic including a medial portion coupled to the circumferential wall and a lateral portion extending outwardly in an anterior direction and/or a posterior direction relative to the medial portion,
wherein—
the first component, the second component, and the circumferential wall define a fluid space within the accommodating intraocular lens, and
when the accommodating intraocular lens is implanted in the eye, the haptic is configured to receive a force from the eye of the patient to (i) pivot the circumferential wall relative to the second component, (ii) adjust a spacing between the second component and at least the outer portion of the first component, and (iii) change a distribution of fluid within the fluid space to change an optical power of the accommodating intraocular lens.
