PROBLEM TO BE SOLVED: To suppress the unintended action of an intraocular lens before making it usable from the state of keeping and transporting an injector.SOLUTION: The intraocular lens insertion system comprises: an intraocular lens insertion implement provided with a lens deformation part wherein an area constituted of an insertion cylinder for inserting the intraocular lens and two openable and closable halved members at the proximal end is provided and the lens is placed inside the area, and an extrusion means for extruding the lens and a holder for fixing the insertion implement. A regulating member for regulating the movement in a closing direction of the halved members in a state where the insertion implement is fixed to the holder and maintaining them in the state of not applying stress to the lens is provided on the holder, and an energizing means for energizing the halved members in the closing direction in the state is included. When the holder is detached from the insertion implement, regulation by the regulating member is canceled, and the halved members are closed to be in a state where the stress can be applied to the lens.COPYRIGHT: (C)2009,JPO&INPIT【課題】 インジェクタが保管、運搬されている状態から使用可能とするまでの間に眼内レンズの意図しない挙動を抑制すること。【解決手段】 眼内レンズを挿入する挿入筒とその基端に開閉可能な2つの半割部材で構成される領域を持ち領域内にレンズを置くレンズ変形部と、レンズを押し出すための押出手段と,を有する眼内レンズ挿入器具と、挿入器具を固定するためのホルダと、を備える眼内レンズ挿入システムで、挿入器具がホルダに固定された状態で半割部材の閉じる方向への動きを規制し、レンズに対して応力を掛けない状態で維持させる規制部材をホルダに設け、この状態で半割部材を閉じあう方向に付勢するための付勢手段と、を有し、ホルダを挿入器具から取り外した際に規制部材による規制が解除され付勢力によってレンズに応力が掛けられる状態まで半割部材を閉じさせる。【選択図】 図6
