Abstract: A method for determining the propensity of an intraocular lens material to prevent posterior capsule opacification is disclosed. The method involves contacting a sample of an IOL material having the shape of an IOL optic with collagen to form a contact area, incubating the sample in a liquid composition comprising lens epithelial cells, determining whether lens epithelial cells grow on the collagen in the contact area.

Abstract: Intraocular lenses include an optic adapted to focus light toward a retina of an eye and a movement assembly coupled to the optic. In one embodiment, the optic has a far vision correction power and the movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic, preferably upon radial compression by a capsular bag of the eye. The optic preferably vaults anteriorly relative to the movement assembly. The movement assembly preferably circumscribes the optic and includes a member having a proximal end portion coupled to the optic and a distal end portion extending away from the optic and adapted to contact a capsular bag of the eye.

Abstract: An intraocular lens implantable in an eye includes an optic for placement in the capsular bag of the eye and for directing light toward the retina of the eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferably both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.

Abstract: An IOL implantable in an eye comprising an optic having an optical portion for directing light toward the retina of the eye and a cell barrier portion for inhibiting cell growth from the eye in front of or in back of the optical portion. The cell barrier portion circumscribes the optical portion, is incapable of focusing light on the retina and includes an irregularly configured structure, for example, irregular grooves. At least one elongated fixation member is coupled to the optic for use in fixing the optic in the eye.
Abstract: A stent in a non-expanded state has a first column expansion strut pair. A plurality of the first column expansion strut pair form a first expansion column. A plurality of second column expansion strut pair form a second expansion column. A plurality of first serial connecting struts form a first connecting strut column that couples the first expansion column to the second expansion column. The first expansion column, the second expansion column, and the first connecting strut column form a plurality of geometric cells. At least a portion of the plurality are asymmetrical geometric cells.
