Abstract
Official abstract text for this publication.
An intraocular lens is disclosed with an optic that changes shape in response to forces exerted by the zonules of the eye. A haptic with an inner and outer ring couples the optic to the capsular bag of the eye. The haptic stresses the optic when the intraocular lens is in a natural state such that the internal stress is present throughout the accommodation range in order to prevent ripples and/or waves in the optic.
First claim
Opening claim text (preview).
What is claimed is: 1. A deformable accommodating intraocular lens for implantation into a capsular bag of an eye, comprising: a deformable optic with a stiffness between 25 kPa and 200 kPa, the optic comprising an anterior face, an opposing posterior face, and a circumference around a perimeter of the optic; and a haptic having a stiffness greater than 500 kPa and comprising a plurality of filaments with an innermost edge and an outermost edge, wherein the plurality of filament…
