    • A surgical method for removing cataracts from the eye by disrupting them but minimizing the danger of piercing neighboring tissue through the use of a phaco-shield (30). The phaco-shield has two flexible flaps (23) which are guided by a Y-shaped wire guide (26) to surround the nucleus of the lens (11). A disrupting probe (40) is inserted through a central opening (24) in the base (22) of the phaco-shield to break up the cataract nucleus (16). The flaps are of a length to cover the end of the probe prior to the probe's contact with the posterior capsule (21) in order to prevent damage to the capsule.
    • 一种外科方法,通过破坏眼睛来消除眼睛中的白内障,但是通过使用超声波屏蔽来最小化穿透邻近组织的危险(30)。 透镜屏蔽件具有由Y形导线器(26)引导以包围透镜(11)的核的两个柔性折片(23)。 破裂探针(40)插入透镜屏蔽体的基部(22)中的中心开口(24)以分裂白内障核(16)。 在探针与后囊(21)接触之前,翼片的长度要覆盖探头的端部,以防止损坏胶囊。
