ABSTRACT:
The intraocular lens includes a lens body having a haptic for supporting the lens body in a human eye. The haptic includes a surrounding portion adapted to engage the tissue of a human eye and which extends at least 360.degree. around the axis of the lens body at a position spaced outward from the periphery thereof. The haptic comprises a single haptic member in one embodiment and a plurality of haptic members in another embodiment each comprising an inner connecting portion having its inner end joined to the periphery of the lens body and extending outward and then around or partially around the axis of the lens body forming the surrounding portion and having an outer portion with an outer end portion. In the case of a single haptic member the haptic member overlaps itself. In the case of a plurality of haptic members each, each haptic member has an outer portion with its outer end portion which overlaps an adjacent portion of another haptic member. A loop or wound or twisted portion is joined to the outer end portion of each haptic member with the inner adjacent portion of the single haptic member or the adjacent inner portion of another haptic member extending through the loop or wound portion such that the outer end portion may be moved along the adjacent portion to decrease or expand the circumference of the surrounding portion of the haptic.
