Phaco one-chop, a hybrid of the phaco-chop, stop-and-chop, and phaco-flip techniques, has 3 main phaco phases: embedding the phaco tip and chopping, flipping the right heminucleus without nucleus rotation, and evacuating the remaining left heminucleus in the bag. Of 198 eyes evaluated, 86% had a Lens Opacities Classification System III cataract grade of 3 to 6. The mean equivalent phaco time (EPT) was 1.9 seconds; for the densest cataracts, the highest phaco power needed was 5.3%. The mean overall power was 2.1%. Thus, the phaco one-chop method requires less EPT and phaco power and allows greater surgeon control for efficiency and predictability than the techniques from which it was derived.
超声乳化一刀劈核术，是超声乳化劈核术、拦截劈核术和超声乳化翻转技术的结合，有3个主要的超声乳化阶段：将超声乳化头嵌入并劈核、翻转右侧半核而不使核旋转、在囊袋内吸出剩余的左侧半核。在评估的198只眼中，86%的晶状体混浊分级系统（Lens Opacities Classification System）白内障等级为3至6级。平均等效超声乳化时间（EPT）为1.9秒；对于最致密的白内障，所需的最高超声乳化能量为5.3%。平均总能量为2.1%。因此，与它所衍生的技术相比，超声乳化一刀劈核术所需的EPT和超声乳化能量更少，并且能让术者更好地控制手术效率和可预测性。
