<p>A haptic for fixation to an intraocular lens implanted in the natural lens capsule of an eye. The haptic comprises a continuous ribbon forming an oblong shape having anterior and posterior portions relative to the elliptical center of the haptic, the ribbon loop includes two or more congruent ribbon arches, and each ribbon arch has a natural index of curvature with an inner and outer edges. It expands in the eye capsule and puts tension on the zonules of the eye. The ribbon affixes to the lens on each side of the optic edge at a point or series of points that provides centration and stability of the optic, and suspends the optic in the open capsular space. The haptic is flexible, and elastic, provides constant, positive force on the capsule throughout all phases of accommodation, thereby preserving tension of the zonules and allowing the capsule to change shape naturally.</p> |
