<p>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.</p> |
