ABSTRACT:
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.
