Accommodating intraocular lens with fluid channels

Abstract

A biomimetic accommodating intraocular lens (AIOL), configured to provide an amount of accommodation to allow a continuous range of vision, includes exterior channel features to control fluid flow around the periphery of the lens. The channel geometry may vary to improve fluid flow and may have a longitudinal profile of constant or varying depth. The number of channels may range from a single channel to numerous channels disposed around the circumference of the lens. The channel(s) may extend radially outward from the edges of the lens optic zones and transit the equator region of the lens body therebetween. The channel(s) allow the eye's aqueous humor to bathe the lens capsular bag, thereby decreasing the incidence of anterior and posterior capsule opacification. The channels allow for a smaller volume IOL to be compressed through a smaller limbal incision and for egress of OVD during the irrigation/aspiration step of cataract surgery.
