PROBLEM TO BE SOLVED: To provide an intraocular lens insertion instrument capable of suitably deforming an intraocular lens and injecting it.SOLUTION: An intraocular lens insertion instrument is such that: when an intraocular lens is inserted into the eye, a first support part is folded to the inside of an optical part by extruding the intraocular lens to a front side passage side by an extrusion member in a state that the first support part is positioned at a tip side of the optical part in a rear side passage, and extruding the intraocular lens to a tip side by the extrusion member in the front side passage； a first inner wall surface is formed in a position at a side in which the root part of the first support part is arranged when the intraocular lens is arranged in the rear side passage, to a central axis in the rear side passage； a first contact part is formed in a position at a central axis side in the rear side passage from the first inner wall surface； and the first contact part is formed in a position in contact with the outer peripheral part of the optical part when the intraocular lens is extruded.SELECTED DRAWING: Figure 20COPYRIGHT: (C)2020,JPO&INPIT【課題】眼内レンズを好適に変形して射出できる眼内レンズ挿入器具を提供する。【解決手段】眼内レンズ挿入器具は、眼内レンズを眼内に挿入するときには、後方通路内にて第１支持部が光学部よりも先端側に位置した状態で眼内レンズを押出部材により前方通路側に押し出した後、前方通路内にて眼内レンズを押出部材により先端側に押し出すことにより第１支持部が光学部の内側に折り曲げられ、第１内壁面は、後方通路の中心軸に対して、後方通路内に眼内レンズが配置されたときに第１支持部の根元部分が配置される側の位置に形成されており、第１内壁面よりも後方通路の中心軸側の位置に第１接触部が形成され、第１接触部は、眼内レンズの押し出し時にて光学部の外周部分と接触する位置に形成されている。【選択図】 図２０
