Abstract
A plate haptic is used with an intraocular lens. 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.
Claims18
An intraocular lens comprising:
- a lens optic;
- and
- a pair of plate haptics coupled to the lens optic, each of the plate haptics having a proximal edge, a distal edge, and opposing lateral edges extending from the proximal edge to the distal edge, the proximal edge of each plate haptic being closer to the optic than the distal edge,
- wherein each plate haptic comprises a pair of appendages at least partially surrounding the optic and entirely displaced from a distal end of said plate haptic, each appendage formed by a portion of one of the lateral edges and a portion of the proximal edge, a proximal end portion of each appendage being spaced apart from the lens optic,
- wherein a longitudinal axis of the intraocular lens extends through each of the plate haptics, a transverse diameter of the lens optic being perpendicular to the longitudinal axis of the intraocular lens,
- wherein a width is measured between medial edges of the proximal end portions of the appendages of the same haptic, the width being greater than the transverse diameter of the lens optic,
- wherein each appendage comprises a plate appendage and is co-planar and unitary or co-extensive with said appendage's respective haptic, the plate appendage being a proximal cantilevered extension of said appendage's respective haptic, and each appendage being spaced laterally and radially outwardly from the optic and terminating in a convex end portion,
- wherein each appendage extends at a non-convergent angle with respect to the other appendage of the same haptic and has a medial edge contoured with respect to the optic,
- wherein each haptic and said haptic's associated pair of appendages together only partially surrounding the optic, each appendage being curved to be partially elliptical in shape and having a width between 2.0 and 7.0 mm,
- wherein the pair of appendages extending from each haptic form a maximum transverse dimension of the intraocular lens that is greater than the transverse diameter of the lens optic, a longitudinal dimension of the intraocular lens measured along the longitudinal axis of the intraocular lens being greater than the maximum transverse dimension.
