PROBLEM TO BE SOLVED: To provide a technique capable of effectively suppressing the occurrence of secondary cataract without complicating an insertion surgery of an intraocular lens.SOLUTION: The intraocular lens comprises: a disk-like optical part 22 with a lens function; and support parts 23 which extend like arms from the peripheral edge 22c of the optical part 22. The root parts 24 of the support parts 23 are formed widely, and through holes 27 are bored in the peripheral part 22d of the optical part 22 at positions near the root parts 24.SELECTED DRAWING: Figure 2 【課題】眼内レンズの挿入手術を面倒なものにすることなく、後発白内障の発症を効果的に抑制することができる技術を提供する。【解決手段】レンズ機能を有する円盤状の光学部２２と、光学部２２の外周縁２２ｃから腕状に延びる支持部２３と、から構成される眼内レンズであって、支持部２３の根元部２４が幅広に形成されるとともに、根元部２４の近傍に位置して光学部２２の外周部２２ｄに貫通孔２７が形成されている。【選択図】図２
