PROBLEM TO BE SOLVED: To provide an intraocular lens insertion device with which the deformation of eye tissue around the incision can be reduced when an intraocular lens is inserted.SOLUTION: The intraocular lens insertion device causes an intraocular lens to advance through the inside of a cylindrical main body part and of an insertion part 20 by a rod-shaped pushing member and to be inserted into the eye from the tip of the insertion part, the intraocular lens comprising an optical part and at least one loop-shaped support part extending outwardly from a periphery of the optical part. An outer peripheral surface of the insertion part has a plurality of protruded portions 210 or recessed portions formed in a front-rear direction of the insertion part at a predetermined pitch P that is equal to or less than the thickness of the eye tissue into which the insertion part is inserted.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】眼内レンズ挿入時に切開創周辺の眼組織の変形を小さくすることができる眼内レンズ挿入器具を提供する。【解決手段】光学部と、光学部の周囲から外側へ延びる少なくとも１つのループ形状の支持部とを備える眼内レンズを、棒状の押出部材により筒状の本体部及び挿入部の内部を進行させて挿入部の先端から眼内に挿入する眼内レンズ挿入器具において、挿入部２０の外周面に、複数の凸部２１０又は凹部が、挿入部を挿入する眼組織の厚さ以下の所定ピッチＰで挿入部の前後方向に形成されている。【選択図】図５
