    摘要： A method of designing an aspheric ophthalmic lens capable of reducing aberration of an eye, comprises: a step of modeling an optical system including a cornea and an ophthalmic lens by inclining the optical system about a rotation point by a predetermined angle in consideration of a displacement angle between an optical axis and a visual axis of the eye (1); a step of calculating aberration resulting from the modeled optical system; and a step of designing a shape of at least one of a front surface and a back surface of the ophthalmic lens to reduce the aberration resulting from the modeled optical system.

    摘要： An intraocular lens (1) capable of obtaining favorab7.e 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 (2), (3) having predetermined refractive power and an elastic part (4) 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.
