An intraocular lens insertion device 1 for inserting an intraocular lens 7 having an optical unit 8 and a pair of support units 9a and 9b into the eye, and a lens installation unit 6 on which the intraocular lens 7 is installed is provided. By moving the insertion instrument body 2 in the direction of the central axis of the insertion instrument body 2, the pusher member 5 that pushes out the intraocular lens 7 from the lens installation portion 6, and the pusher member 5 moves in the direction of the central axis of the insertion tool body 2 And a guide slope 11 that guides the movement of the push-out member 5. When the pusher member 5 moves in the central axis direction of the insertion instrument body 2, the distal end portion of the pusher member 5 contacts the support portion 9 b of the intraocular lens 7 and contacts the optical portion 8 while pushing the support portion 9 b. The guide slope 11 guides the distal end portion of the pushing member 5 so as to be displaced in the vertical direction.光学部8と一対の支持部9a,9bとを有する眼内レンズ7を眼内に挿入する眼内レンズ挿入器具1であって、眼内レンズ7が設置されるレンズ設置部6が設けられた挿入器具本体2と、挿入器具本体2の中心軸方向に移動することにより、レンズ設置部6から眼内レンズ7を押し出す押出部材5と、押出部材5が挿入器具本体2の中心軸方向に移動する際に、押出部材5の移動をガイドするガイドスロープ11と、を備える。押出部材5の先端部は、挿入器具本体2の中心軸方向に押出部材5が移動する際に、眼内レンズ7の支持部9bに接触し且つ支持部9bを押し込みながら光学部8に接触し、ガイドスロープ11は、押出部材5の先端部が上下方向に変位するようにガイドする。
