摘要:
An intraocular lens in which deterioration in contrast is suppressed even when the optical axis of the intraocular lens is decentred from the optical axis of the eyeball when the intraocular lens is inserted into the eye while the advantage of a conventional aberration reduction type intraocular lens that the image is seen clearly is sustained by employing such a power distribution as respectively having at least one positive power deviation region (E1) having a power larger than that represented by the reference power distribution and at least one negative power deviation region (E2) having a power smaller than that represented by the reference power distribution in the central region of the intraocular lens assuming that a power distribution being set to cancel the spherical aberration of cornea when the intraocular lens is inserted into the eye is the reference power distribution.
