Abstract: An accommodating intraocular lens including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. Each flexible attachement component is durable and formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The subject durable accommodating intraocular lens enables axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force.

Abstract: An intraocular lens including an optic portion having an outer peripheral edge and two, three or four balanced looped haptic elements for use to achieve refractive correction. Each looped haptic is formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is designed with specific flexibility characteristics so as to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.

Abstract: A surface treated intraocular lens implant for use in the replacement of a cataractous natural lens to prevent posteriror capsular opacification. The surface treated intraocular lens includes one or more proteins, polypeptides, polyamino acids or polyamines bound to the surface of the intraocular lens implant covalently, non-covalently or a combination thereof. The one or more proteins, polypeptides, polyamino acids or polyamines present on the surface of the intraocular lens implant serves to reduce or eliminate residual lens epithelial cell migration within the lens capsule. By preventing residual lens epithelial cell migration, posterior capsular opacification of the intraocular lens implant is thus reduced or eliminated.

Abstract: A refractive anterior chamber intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably three or four haptic elements. Each haptic element is of like form. Each haptic element is also manufactured to have an inner portion and an outer portion for supporting the optic portion in a patient's eye. The inner portion of each haptic element is preferably permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a contact button and a central portion located between the contact button and the inner portion. Each haptic is formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is so designed to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.

Abstract: A method of cast molding an intraocular implant from two or more dissimilar materials using disposable molds. The subject cast molding method is particularly useful in the production of intraocular lenses manufactured from dissimilar materials. It is desirable to produce intraocular lenses from dissimilar materials in order to optimize the optical characteristics of the intraocular lens optic portion and to optimize stability and flexibility characteristics of the intraocular lens haptic elements.

Abstract: A process for imparting a glare resistant zone to an intraocular implant such as an intraocular lens using a highly regulated spray of an abrasive material. The spray is preferably of air and aluminum oxide, which may be washed from the intraocular implant during cleaning and polishing thereof. The process is suitable for any machinable intraocular lens material such as acrylates, methacrylates and hydrogels.

Abstract: An opthalmic lens and a method of making is disclosed. The lens has a one-piece lens body with an integral edge surface. The edge surface reflects visible light which contacts the edge surface away from the retina of the patient. The edge surface has beveled portions or a curve of a convex form. The bevels or convex form are displayed on the edge by milling with a milling cutter having a shape matching that desired on the edge. This lens design reduces glare seen by the patient caused when incident light contacts the edge surface and is undesirably reflected onto the retina.

The loading area has a distally extending slot in the wall which allows for easy removal of a forceps holding the IOL from the chamber following insertion of the IOL into the chamber with the forceps. The staging area holds the IOL in a folded state until the chamber is placed into an IOL insertion instrument having a plunger which forces the IOL distally out of the staging area and into the eye through the distal tip.
