Experience with the Harrington erisophake in fifty cataract extractions.

IN 1951, Dr. David Harrington of the Division of Ophthalmology, University of California, San Francisco, sent me one of his erisophakes. Since then I have used the instrument sporadically, by which I mean that in an operating list oftwo, three, or four cataract extractions, an occasional one was done with the erisophake, the rest in the ordinary way. Fifty such extractions have now been performed and a note of my experience may be of some interest to others who may contemplate using this instrument. The phakoerisis of Barraquer Barraquer and Barraquer Moner in Barcelona is very impressive to watch, and the results obtained at their hands seem excellent, but the space-and-time-machine-like meter on one of the operating theatre walls which has to be watched and consulted, and on which the amount of suction seems to depend, is rather awe-inspiring.
