PROBLEM TO BE SOLVED: To provide an intraocular lens insertion instrument capable of inserting an intraocular lens in which a support part is subjected to tacking, into an eye of a patient, with a simple structure.SOLUTION: An intraocular lens 1 comprising an optical part 2 and support parts 3a, 3b extending outward from a peripheral edge of the optical part is mounted on a mount part 25, the intraocular lens is extruded by a plunger which is movable in a tip direction of an extrusion axis A to insert the intraocular lens into the eye of the patient. The mount part comprises: a mount surface on which the optical part is mounted； and engagement parts 51, 55 arranged above the optical part mounted on the mount surface, and engage to the support parts whose tip ends are deformed to be arranged inside the optical part. The engagement parts comprise a first support part for supporting the support parts from a lower side, and a second support part provided on a base end side of the extrusion axis relative to the first support part and supporting the support parts from the base end side.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】簡素な構成ながらも支持部をタッキングした眼内レンズを患者眼に挿入できる眼内レンズ挿入器具を提供する。【解決手段】光学部２と光学部の周縁から外側に伸びる支持部３ａ、３ｂとを有する眼内レンズ１を載置部２５に載置し、眼内レンズを押出軸Ａの先端方向に移動可能なプランジャーで押し出して患者眼に眼内レンズを挿入する眼内レンズ挿入器具であって、載置部は、光学部が載置される載置面と、載置面に載置される光学部よりも上方に配置され、先端が光学部の内側に配置されるように変形された支持部を係止する係止部５１、５５と、を備え、係止部は、支持部を下方から支持する第１支持部と、第１支持部よりも押出軸の基端側に設けられ、支持部を基端側から支持する第２支持部とを備える。【選択図】図５
