In recent years a number of publications have dealt with improvements and changes in phakoerisis. However, except for several slight changes, Stoewer's suction cup, as described in 1902, has remained essentially unaltered.1 The vacuum has been produced either by a small rubber bulb or by a motor pump. The newer instruments have become more complicated, more liable to defects, and more expensive. Barraquer's contribution consisted of creating a stronger vacuum by the use of an electric pump.

After the introduction of α-chymotrypsin,2 we at the Hamburg University Eye Department started to use a new type of erysiphake which has the advantages of being inexpensive, effective, and less noisy than the motor-driven pump.*3 In addition, the vacuum, instead of being discontinuous and causing added strain and tearing of the capsule as that noted in the motor pump, proved by the method we are about to describe to be continuous.
