Abstract: A elastically deformable intraocular lens (IOL), adapted for double folding and implanting in the iridocorneal angle or ciliary sulcus of an eye. The IOL includes an optic having a long axis and an orthogonal transverse axis passing through the optical axis and a diameter of between about 5 mm and about 7 mm. First and second fixation members are joined to or at opposite edge regions of the optic. The first fixation member is generally &pgr;-shaped, having a base region with a width parallel to the transverse axis no greater than about 3 mm, and includes a pair of similar, spaced apart haptics, proximal ends of which are symmetrically joined to the base region and which diverge outwardly from the long axis at between about 30 and about 45 degrees. The two haptics are constructed to flex in the plane defined by the unflexed haptics during IOL double folding of the IOL and unflex in the same plane after the IOL is implanted in an eye.

Abstract: An improved method of inserting an intraocular lens into an eye comprising removing an existing lens so as to leave a capsular bag intact; at least partially inserting an intraocular lens having at least one haptic incorporating an aperture therein into the capsular bag; and inserting a capsular tension ring into the capsular bag such that the capsular tension ring passes through the aperture is disclosed. A replacement lens arrangement and a sterile packaging therefore are also disclosed.

Abstract: An iris-supported intraocular lens having an optic portion and a plurality of fixation members coupled thereto. Each fixation member has a pair of pincer arms that separate outward of the optic and converge toward one another at aligned end tips.

The soft sleeves eliminate damage to the iris tissue.

Abstract: A corneal ring for the correction of the refractive power of an eye consists of a part of metal or plastic which is formed into a split ring having at least one turn, or into a ring segment having a diameter or effective diameter matched to the periphery of the cornea of an eye. The ring or ring segment is inserted into a ring channel which is formed with a special instrument in the cornea of the eye and the radius of curvature of the ring or ring segment is subsequently adjusted by a laser beam, or by radiation, or electromagnetic induction, or magnetism to achieve a fine correction of the refractive power of the eye.

Abstract: An intraocular lens insertion device having a tubular member for receiving the lens and a plunger for pushing the lens into the eye. The lens is held in a suspended position by its haptics so that the optic portion of the lens does not contact the interior of the tubular member. The plunger tip is provided with a slot for holding the lens after it is expelled from the tubular member into the eye in order to alleviate the risks associated with uncontrolled unfolding of the lens or uncontrolled expulsion of the lens from the inserter into the eye.

Abstract: Haptics for an intraocular lens are attached to a flexible, deformable optic which is capable of being rolled for insertion through a small incision in the cornea. The outer periphery of the optic is circular. The haptics include a pair of stems extending radially on diametrically opposite sides of the optic. The stems are rectangular in cross section, having greater width than thickness to permit greater flexibility anterior to posterior than superior to inferior. A flexible support bar is mounted at the end of each stem, each bar being bisected by its stem respectively, and being shaped like an arc concentric with the optic. The support bar has greater depth than width, in order to permit greater flexibility proximally and distally than anteriorly and posteriorly. The haptics have a haptic arm mounted in cantilever fashion at the ends of each support bar, each of the arms terminating in a circular or lobular footplate.
