The delivery of the crystalline lens by the use of suction, termed phako erisis by Barraquer,1 has enjoyed a period of popularity over the past 50 years. His original description in 1916 incorporated a motor driven pump connected to an erisophake by a rubber tube. This was modified by Dimitry2 in 1939 who advocated the use of a simplified sucking-disc instrument. It used less suction and, therefore, limited the hazard of extreme suction on the vitreous and iris, as well as on the lens capsule itself. In 1948, Bell3 devised a surgical instrument which consisted of a small rubber contact glass sucker and a Dimitri tip. In 1951, Harrington4 further modified Bell's erisophake by using a solid handle rigidly fastened to the needle holding the suction cup. This eliminated the chance of pressure on the rubber ball and the loss of suction on the lens
