The insertion instrument of the eye interpolation necessary lens, makes the substance and the lens move which possess the insertion tube section which sends out the lens inside the eye from the lens accommodation section and advanced opening which accommodate the lens from the lens accommodation section, possesses with the extrusive axis which is pushed out inside the eye through the insertion tube section. The said insertion instrument, the liquid from inside the substance or has, the liquid passage other than advanced opening in order to flow inside the substance outside. And, the said insertion instrument when the lens insertion tube circles moves facing toward advanced opening, opens the liquid passage, when the lens from advanced opening is sent out inside the eye, possesses the structure which cuts off the liquid passage.< Selective figure > Figure 7眼内挿入用レンズの挿入器具は、レンズを収容するレンズ収容部および先端開口からレンズを眼内に送り出す挿入筒部を有する本体と、レンズをレンズ収容部から移動させ、挿入筒部を通して眼内に押し出す押出し軸とを有する。該挿入器具は、液体を本体の内部から外部に又は本体の内部で流動させるための、先端開口以外の液体流路を有する。そして、該挿入器具は、レンズが挿入筒部内を先端開口に向かって移動するときは液体流路を開放し、レンズが先端開口から眼内に送り出されたときに液体流路を遮断する構造を有する。【選択図】 図7
