Abstract: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a single optical power IOL adapted for accommodating movement.

Abstract: A narrow profile, glare reducing, refractive mono-focal intraocular lens is described that comprises an optic having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range. A transition zone between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens is implanted. The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.

Abstract: A supplemental intraocular lenses may be attached to conventional primary intraocular lenses using annular wrap-around clamps or adhesive. New primary intraocular lens configurations have pockets for accommodating relatively small, supplemental intraocular lenses therein.

Abstract: Ophthalmic lenses, for example, intraocular lenses, contact lenses, corneal implant lenses and the like, have multifocal characteristics which provide beneficial reductions in at least the perception of one or more night time visual symptoms such as “halos”, and “glare or flare”.

Abstract: There is disclosed an accommodating intraocular lens for implantation in an eye having an optical axis. The lens comprises an anterior portion which in turn comprises an anterior viewing element and an anterior biasing element. The lens further comprises a posterior portion which in turn comprises a posterior viewing element in spaced relationship to the anterior viewing element and a posterior biasing element. The anterior portion and posterior portion meet at first and second apices of the intraocular lens. The anterior portion and the posterior portion and/or the apices are responsive to force thereon to cause the separation between the viewing elements to change. Additional embodiments and methods are also disclosed.

Abstract: An improved opthalmic lens is disclosed which has a plurality of alternating power zones with a continuously varying power within each zone, as well as in transition from one zone to another. In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa. This change is continuous (progressive), without any abrupt correction changes, or “edges”.

Abstract: An intraocular lens has an optic and two fixation members. Each fixation member has at least one connecting element and a pincer element. The pincer element has a side region with a central portion and opposed end portions. The pincer element further has a pair of pincer arms attached end-to-end from respective opposed end portions of the side region. In one embodiment, the side region has a first location disposed closer to the optic than the pincer gap and a second side region disposed further from the optic than the pincer gap. The distance of both side regions to the central-most portion of the pincer gap is substantially identical.

Abstract: An instrument for implanting an elastically foldable intraocular lens in an eye is described. The instrument comprises a barrel having proximal and distal ends and a nozzle having a slender ocular insertion end region sized for insertion through an ocular incision no greater than about 3.7 mm., the nozzle being attached to the distal end of the nozzle. The barrel includes an intraocular lens holding chamber upstream of the nozzle. First and second shield elements are disposed inside along opposite side regions of the nozzle, each of the shield elements having an elastically deformable protective shield region disposed in the nozzle in an elastically deformed state.

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.

In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa. This change is continuous (progressive), without any abrupt correction changes, or “edges”. Two versions of the invention are disclosed. In the first version continuous, alternating power variation is accomplished by a continuously changing curvature of the lens posterior surface, thereby altering the angle of impact of light rays on the eye.

Abstract: An iris fixated intraocular lens for implanting in the anterior chamber of an eye comprises an optic having an optical axis and anterior and posterior sides; and first and second fixation members, each of the fixation members having a proximal end region and a distal end region. The proximal end region of each fixation member is a single flexible strand fixed to an edge region of the optic to extend generally tangentially outwardly therefrom and the distal end region is formed into a loop having defined therein at least one narrow iris pincher gap for detachably attaching the intraocular lens to the anterior surface of the iris. The first and second fixation members are substantially identical to one another and are attached to the optic on opposite sides of the optical axis.
