    摘要： An intraocular lens (1) capable of suppressing an aftercataract with a simple constitution. The intraocular lens includes a foldable optical part (2) which has a shape of refractive surfaces determined in accordance with refractive power to be provided to the optical part, and a supporting part (3) which is jointed to an edge portion of the optical part while being inclined to a plane orthogonal to an optical axis of the optical part, wherein a joint portion of the optical part with the supporting part has a thickness that is deformed due to a stress generated by a pressure applied to the supporting part at the time of arrangement inside an eye (E) regardless of the shape of the refractive surfaces.

    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.
