Problem to be solved: to provide an intraocular lens insertion device capable of preventing the backflow of the perfusion liquid to the intraocular lens insertion device in the intraocular lens insertion operation which forms the anterior chamber space in the eye using a liquid having a viscosity lower than that of a viscoelastic material.Solution: an intraocular lens insertion device is inserted into a substantially cylindrical shaped insertion member inserted into the eye, an intraocular lens extruded member 30 which pushes an intraocular lens into the eye from an insertion member and moves an inside of the insertion member by pushing an intraocular lens, and an intraocular lens extruded by an intraocular lens extruded member. A closed member 31d is formed to close the gap between the insertion member and the intraocular lens extruded member.Diagram【課題】粘弾性物質よりも粘性が低い液体を灌流液として用いて眼内の前房空間を形成する眼内レンズ挿入手術において眼内レンズ挿入器具への灌流液の逆流を防止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】眼内レンズ挿入器具を、眼内に挿入される略筒形状の挿入部材と、眼内レンズを押圧して挿入部材内を移動させ、挿入部材から眼内に眼内レンズを押し出す眼内レンズ押出部材30と、眼内レンズ押出部材によって眼内レンズが眼内に押し出されるときに、挿入部材と眼内レンズ押出部材との間隙を閉塞する閉塞部材31dとを有する構成とする。【選択図】図5
