    摘要： An intraocular lens for amblyopia designed in consideration of normalizing vision as well as magnifying vision, is provided with an optical part having predetermined refractive power, which includes front and rear side refractive surfaces, a supporting part for supporting the optical part within the eye, a first reflecting part formed at a rear surface side of the optical part for reflecting an incident light bundle, which has passed through the front surface of the optical part, toward the front surface, and a second reflecting part formed at a front surface side of the optical part for reflecting the incident light bundle, which has been reflected by the first one, toward the rear surface, wherein the first and second reflecting parts form a reflecting telescopic system which forms a magnified image on a retina, and at least one of them has a property of transmitting a part of the light bundle.

    摘要： A method of manufacturing an intraocular lens includes: a first step of producing a base material for the intraocular lens by polymerizing a first polymerizable monomer which is a raw material of the base material; a second step of producing a monomer-impregnated base material by impregnating the base material produced in the first step with a second polymerizable monomer; a third step of setting a protective member on a surface of the base material produced in the second step to prevent the surface of the base material from drying; and a fourth step of polymerizing the second polymerizable monomer impregnated in the base material on which the protective member is set.

    摘要： An intraocular lens capable of obtaining favorable accommodative power, which is to be arranged inside a lens capsule as a replacement for a crystalline lens, includes a front-side and rear-side optical parts having predetermined refractive power and an elastic part having predetermined elasticity by containing water to swell, wherein the elastic part is bonded to the optical parts so that optical axes of the optical parts coincide and so that the elastic part does not cover their optical zones, an elastic part thickness before containing water is determined so that an intraocular lens thickness after containing water completely to swell corresponds to a crystalline lens thickness at near vision, and a distance between the rear surface of the front-side optical part and the front surface of the rear-side optical part of the intraocular lens arranged inside the lens capsule is changed according to relaxation and tension of a ciliary muscle.
