PROBLEM TO BE SOLVED: To provide a lens-holding device for surgery, which can certainly hold a lens on a pupil position even if an eyeball is moved and can control problems such as invasion by conventional suture to the minimum.SOLUTION: A lens-holding ring 50 is held between portions of a cord-like body 40a stretched along the surface of the eyeball 1 by being supported by two or more cannulas 21 and 22 which are stabbed into a sclera 2, is fixed to the surface of the eyeball 1 by the tension of the cord-like body 40a, and holds a lens 30 for the surgery on the eyeball in that state. The lens-holding ring 50 has a lens-holding body 51 with an opening 52, in which the lens is inserted, and engaging parts 57 disposed at opposed positions across the opening 52. The engaging part has an engagement structure, which engages the cord-like body 40a for fixing the lens-holding body to the surface of the eyeball so as to clamp the lens-holding body, and a turn-back part 58 at the tip of the engaging part for preventing the cord-like body from coming off.COPYRIGHT: (C)2011,JPO&INPIT【課題】眼球を動かしても瞳孔位置に確実にレンズを保持しておくことができ、従来の縫着による侵襲等の問題を最小限に抑制できる手術用レンズ保持装置を提供する。【解決手段】レンズ保持リング50は、強膜2に刺し込まれた複数のカニューラ21、22に支持を取ることで眼球1表面に沿って張設された紐状体40aの間に挟まれ、紐状体40aの張力により眼球1表面に固定され、その状態で手術用レンズ30を眼球上に保持する。レンズ保持リング50は、レンズを挿入する開口52を備えるレンズ保持体51と、開口52を挟んで対向する位置に設けられた係合部57とを有する。係合部は、レンズ保持体を挟み込むようにしてレンズ保持体を眼球表面に固定する紐状体40aを係合する係合構造を有し、係合部の先端に紐状体の外れ止め用の返し部58を有する。【選択図】図1
