Abstract:
1. An accommodating intraocular lens (AIOL) adapted for implantation in a posterior chamber of an eye, comprising: an optic comprising two optical regions having an identical optical power and adapted to produce a trapezoidal phase shift, the trapezoidal phase shift being a linear change between the two regions in the phase shift imparted to incoming light as a function of radius; a plurality of haptics, each haptic extending from a haptic-optic junction to at least one transverse arm adapted for contacting a capsular bag of the eye and each haptic having sufficient length and rigidity to stretch a capsular bag of the eye to contact ciliary muscles of the eye; wherein the haptic-optic junctions vault the optic forward relative to the haptics and compression of the haptics by the ciliary muscles exerts a forward force at the optic of at least 1.5 mN, wherein the trapezoidal phase shift augments the visual effect of the forward force to produce a combined effective power change of at least 0.75 Diopters.
