Ophthalmologists are generally agreed that in the extracapsular operation the procedure with the forceps, when properly executed (especially with an instrument in which the spring offers little resistance and the span between the blades is not greater than about 6 mm.) gives a better result than any of the various types of incision with the cystotome. The removal of a generous piece of capsule permits the lens to be expressed more easily and the cortex to be evacuated more effectively, and absorption of the remnants of
