A technique for nucleus removal following circular capsulorhexis is described. After a continuous circular capsulotomy, soft surface cortex surrounding the nucleus is aspirated by an irrigation/aspiration device to separate the nucleus from cortical material and reduce its diameter. With phacoemulsification, the separated nucleus is rotated within the capsular bag and emulsified. With planned extracapsular cataract extraction, the upper nucleus equator is brought out of the capsular bag using an irrigating capsule retractor. The nucleus is then delivered by simple expression or by a Nishi delivery cannula.
描述了一种环形撕囊后取出核的技术。连续环形撕囊后，用灌注/抽吸装置吸出核周围的软皮质表面，以将核与皮质物质分离并减小其直径。使用超声乳化时，分离出的核在囊袋内旋转并乳化。对于计划行囊外白内障摘除术，使用灌注式囊膜牵开器将核的上赤道部带出囊袋。然后通过简单挤压或使用西氏输送套管取出核。
