During the last few decades, phacoerisis has achieved increasing popularity as a method of delivering the cataractous lens from the eye. The early work of Stoewer,1 Hulen,2 and Barraquer3,4 laid a firm foundation for the many modifications of the suction cup and apparatus that were to come. An excellent suction cup was constructed by Dimitry5 in 1939, after considerable inquiry into the physical aspects of vacuum production in phacoerisis. Floyd and Grant,6 in 1946, used the Dimitry tip in conjunction with a small spring-operated syringe. The vacuum could be established easily and accurately, and this device was a great improvement over existing instruments. Bell,7 in 1948, introduced a new tip attached to a rubber bulb which provided fingertip control and comparatively easy manipulation. The indefinite vacuum level and excessive flexibility exhibited by this instrument have proved a disadvantage in some instances. Thomas8 considered
