An intraocular lens is unitarily formed with a lens body and two undulating shaped haptics formed of four segments which alternatingly curve in opposite directions to provide alternate troughs and protrusions which provide stability after positioning in the eye and which also cooperate with a unique implement to permit an easy positioning of the lens in the lens capsule following removal of the natural lens. Two disclosed embodiments of the lens comprise a vaulted lens and a non-vaulted lens.

Intraocular lens

An intraocular lens for positioning in either the anterior or posterior chambers of the eye includes a lens body having first and second support members extending from the lens body for engaging adjacent portions of the anterior or posterior chamber of the eye, each comprising a resilient spring-like asymmetric support loop extending outwardly from the periphery of the lens body and having first and second parallel end portions embedded in chordal bores in the periphery of the lens body; first and second sloped leg portions of different lengths extend outwardly from the end portions and a transverse portion extends transversely from outer ends of the first and second leg portions and includes contact foot portions on each end which are separated by an inwardly extending arcuate connector portion.

Multi-positionable intraocular lens

A positioning implement for an intraocular lens comprises an elongated plate-like handle having an upper surface on which a movable pusher having a tapered forward end is mounted for axial reciprocation. A canted finger extends unitarily forwardly from the handle and also has a tapered forward end. Both tapered forward ends are provided with slots dimensioned to fit over an intraocular lens haptic to permit selective application of force to the haptic of an intraocular lens at two different locations for positioning it in the lens capsule of the eye.

Positioning implement for intraocular lens

An intraocular lens assembly for positioning in the posterior chamber of the eye has a plastic lens body supported in the eye by first and second flexible spring-like resilient support loops of circular cross-section extending symmetrically from opposite sides of the peripheral edge of the lens body; the outer end of each support loop is received in and biased against the equatorial region of the lens capsule of the eye from which the natural lens has been removed and has first and second outwardly protruding arcuate contact feet engaging the capsule and separated by an inwardly extending arcuate connector portion with first and second support legs extending from the opposite ends of the contact feet to chordal openings in the periphery of the lens body in which the inner ends of the support legs are fixedly embedded.
