A plate haptic is used with an intraocular lens optic displaceable in response to vitreous pressure changes. The plate haptic comprises: a plurality of opposing lateral portions; a distal portion having a plurality of opposing projections extending substantially laterally therefrom; and a proximal portion comprising a strap across which is a hinge connecting the lens optic to the haptic. The intersection of the proximal portion with each lateral portion forms a plurality of appendages, or paddles, to partially surround the optic. The appendages, projections, and hinged straps combine to substantially aid displacement of the lens optic in response to changes in vitreous pressure. |
