Abstract
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.
