THE GRASPING of the lens capsule by suction for cataract extraction has appeared to many surgeons to be the ideal method. Whether this method is superior to the use of a satisfactory capsule forceps is a question which will not be answered for many years, until the manually operated erysiphake shall have been tried by many surgeons with all types of cataracts. Dimitry,1 Bell,2 and Harrington3 have pointed out the advantages of the simplified erysiphake over the mechanical vacuum-pump erysiphake. Harrington3 has described a simplified instrument and has also indicated the need for further improvement and simplification.
Manually operated suction devices appear to have two chief weaknesses: awkwardness of manipulation and a very limited degree of vacuum. It has been demonstrated that the high degree of suction produced in pump-operated devices is not necessary, and may even be hazardous. On the other hand, the manually operated
