The present invention relates to an intraocular lens insertion device capable of stabilizing the behavior of an intraocular lens during injection.An intraocular lens insertion device having a substantially cylindrical instrument body having an insertion tube (100) at its tip to insert an intraocular lens into an eye and a plunger for moving an intraocular lens to a distal end of an insertion tube (100), an insertion tube (100) is an eye An opening end surface of an opening (100a) having an opening (100a) for injecting an inner lens is an inclined surface inclined to a plane perpendicular to a central axis (o) of an insertion tube, and an insertion tube of an opening end face of an inside wall of an insertion tube part (100) AfterBy the first region to at least a portion of the second region (100g) opposing the central axis (o) to the first region (100h) extending from the proximal end (100F) to the rear end side of the insertion tube (100) to the rear end of the insert tube A frictional force imparting portion for supporting the intraocular lens is provided with a frictional force greater than the frictional force acting on the intraocular lens.眼内レンズの射出時の挙動を安定させることができる眼内レンズ挿入器具に関する。眼内レンズを眼内に挿入する挿入筒部(100)を先端に有する略筒状の器具本体と眼内レンズを挿入筒部(100)の先端に移動させるプランジャーとを有する眼内レンズ挿入器具であって、挿入筒部(100)は、眼内レンズを射出するための開口部(100a)を有し、開口部(100a)の開口端面は、挿入筒部の中心軸(O)に直交する面に対して傾斜した傾斜面であり、挿入筒部(100)の内壁面のうち、開口端面の挿入筒部の後端側に位置する基端(100f)から挿入筒部(100)の後端側に所定長さ延伸する第1 の領域(100h)に中心軸(O)を挟んで対向する第2 の領域(100g)の少なくとも一部に、前記第1 の領域によって前記眼内レンズに働く摩擦力よりも大きい摩擦力が前記眼内レンズに働くための摩擦力付与部が設けられる。
