Intraocular lens and manufacturing method thereof

An object of the present invention, while securing sufficiently large effective optic can exhibit an excellent inhibitory effect against cataract is to provide an intraocular lens of novel structure. To solve such problems, the present invention, at least a portion of the lens surface 16,18,30 in the circumferential direction with a width dimension of depth and 0.1~2.0μm of 0.01~1.0μm as cell-derived region 26, 32 a number of linear fine irregularities 28 extending a predetermined length is formed directly, and the lens surface in continuous linkage structure in the circumferential direction of the lens surface 18, 30 the fine small irregularities 28 18 by the periodically arranged periodic structure in the radial direction of 30, in the cell inducing region 26, 32 of the linear fine irregularities 28 allowed without a gap formed over the entire of the cell inducing region 26, 32 the visible light transmittance was 60% or more.
