An intraocular lens wherein an outer edge of a support part has a curved concave shape at a base thereof and extends therefrom toward a tip thereof with a curved convex shape having a radius of curvature of 5.25 to 7.50 mm. In a region where a Y coordinate of an orthogonal coordinate system is 1.0 mm or greater, an origin of the coordinate system being a geometric center of an optical part, an inner edge of the support part is positioned between shapes obtained by offsetting the outer edge of the support part by 0.2 mm and by 1.0 mm towards the X-axis origin. The tip of the support part is positioned in a region where the Y coordinate is greater than a radius of the optical part, outside a circle with a radius of 5.0 mm centered on the origin.

Intraocular lens

A method of disinfecting a contact lens is provided, including the steps of preparing a disinfecting liquid which contains hydrogen peroxide and at least one metal phthalocyanine compound dispersed or dissolved in an aqueous medium, immersing the contact lens in the disinfecting liquid, and irradiating the disinfecting liquid in which the contact lens is immersed with a light.

Method of disinfecting contact lens and disinfecting liquid for the method

A method of disinfecting a contact lens is provided, including the steps of preparing a disinfecting liquid which contains water-dispersible fine particles of a titanium oxide dispersed in an aqueous medium, immersing the contact lens in the disinfecting liquid; and irradiating the disinfecting liquid in which the contact lens is immersed, with a light.

A soft intraocular lens container having a folding function comprises a base plate having a groove a lens receiving mechanism formed in the base plate and a cover wherein the lens receiving mechanism comprises a pair of holding portions each formed at each side portion of the groove which are adapted to receive haptics h of a soft intraocular lens, and clamping portions each formed on each of the holding portions which clamp an optical portion o of the soft intraocular lens having the haptics h to be put on said holding portions and wherein the base plate is capable of folding the optical portion o of the soft intraocular lens held between said clamping portions into two when both sides of the base plate are clamped so that the base plate is pressed toward the groove and the cover has a plurality of bayonet pawls projecting toward a rear surface side of the cover, the bayonet pawls being capable of engaging with bayonet openings formed in the base plate at both side portions with respect to the groove whereby the cover covers the soft intraocular lens received in the lens receiving mechanism and is fixed to the both side portions of the base plate
