A new instrument for use in prolapsing a cataract nucleus into the anterior chamber during extracapsular cataract extraction is described. This instrument is a modification of the Kelman Blunt Irrigating Cystatome and the Youens Lens Manipulating Cannula. The tip is elongated, rounded, broadened, and set at an angle from the instrument shaft to enhance broad surface contact of the instrument tip with the nucleus equator. In a recent series of 100 consecutive cataract procedures it was possible to completely prolapse the nucleus into the anterior chamber in all but six cases. The surgical technique is described.
本文描述了一种用于在白内障囊外摘除术中将白内障核送入前房的新型器械。该器械是对凯尔曼钝头冲洗式晶状体囊刀和尤恩斯晶状体操作套管的改良。其尖端拉长、呈圆形、变宽，并与器械轴成一定角度设置，以增强器械尖端与核赤道的宽面接触。在最近连续进行的100例白内障手术中，除6例之外，其余病例均能将核完全送入前房。文中描述了手术技术。
