We present a new combined irrigating and suction tip which greatly simplifies the technic for extraction of soft cataract. It consists of a double-barreled needle for injecting solution into the anterior chamber while oral suction is maintained through the second, or larger, barrel.
The double-barreled suction tip (A) is inserted into the anterior chamber (E) through the keratome incision (FF). The contents of the lens are drawn up into the glass trap (B) by oral suction (C). Physiologic solution of sodium chloride is simultaneously injected into the anterior chamber by means of the syringe (D).
A narrow keratome picks up the conjunctiva 3 mm. back of the limbus and enters the anterior chamber. The anterior capsule is slit in the ninetieth meridian by the point of the keratome. The doublebarreled needle is inserted and the lens cortex aspirated. Fluid is then injected and the aspirating continued until the Hildreth
