摘要:
An intraocular lens (100) insertion apparatus (10) comprising a hollow tube (14) made of polypropylene and having an interior wall (53) defining a hollow space (58) through which an intraocular lens is passed and an outlet (26) through which said intraocular lens is passed from said hollow space into an eye; and a coating secured to said interior wall of said hollow tube, wherein the coating comprises polyvinylpyrrolidone, wherein the polyvinylpyrrolidone is physically secured, other than by covalent bonding, to said interior wall.
摘要:
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. The present IOLs inhibit cell growth from the eye in front of or in back of the optic and reduce glare obtained in the eye in which the IOL is located.
摘要:
There is provided an intraocular lens, comprising: an optic (110) sized and adapted for placement in the capsular bag of the eye and for directing light toward the retina of the eye, the optic having: a central optical axis (OA); a convex anterior face (AF) and a convex posterior face (PF) for focusing light rays striking the anterior face onto the retina of the eye; a peripheral edge (112) disposed between the anterior and posterior faces circumscribing the optic, at least part of the peripheral edge being roughened; and a peripheral edge corner (116) formed at an intersection at the peripheral edge and the convex posterior face, the peripheral edge corner being located at a visible discontinuity; and a plurality of fixation members integral with the optic, the intraocular lens consisting of one piece, with unitary optic and fixation members.
