AI Technical Summary

Problems solved by technology

Existing AIOLs may also be too large to be inserted through the small incision in the eye, and the incision may need to be somewhat larger than ideal
Also, at least some existing AIOLs may be unstable when placed in the eye, which may lead to incorrect accommodation and other errors

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 outerfluid 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 opticalpower changes. A third lens component coupled to the first or second component provides additional optical power.

Description

[0001] Related Application Cross Reference [0002] This application claims U.S. Provisional Application No. 62 / 438,969, filed December 23, 2016, entitled "Multiple-Piece Accommodative IOL," filed August 11, 2017, entitled "Multi-Piece Accommodative IOL" U.S. Provisional Application No. 62 / 544,681, priority to U.S. Provisional Application No. 62 / 549,333, entitled "Multi-Piece Accommodative IOL," filed August 23, 2017, the contents of which are incorporated herein by reference in their entirety. Background technique [0003] The present disclosure relates to medical devices and methods. In particular, the present disclosure relates to accommodative intraocular lenses (hereinafter "AIOLs" or "AIOL" in the singular). [0004] Cataracts affect a large proportion of the adult population worldwide, causing clouding of the native crystalline lens and loss of vision. Patients with cataracts are treated with native lens removal and surgical implantation of a synthetic intraocular len...
