We describe a technique that relocates the phacoemulsification process outside the capsular bag by transposing the nucleus through an intact 5.0 to 6.0 mm capsulorhexis. The upside-down nucleus is then returned to the posterior chamber, positioned above the anterior capsule in the "supracapsular space" where it remains throughout the phacoemulsification procedure of choice: cracking, chopping, manual prechoping, or traditional sculpting. The chief advantage of supracapsular phacoemulsification is greater efficiency, which is manifested in reduced emulsification time and energy. Disadvantages include the possibility of mild postoperative corneal edema during the earliest part of the learning curve, as well as inadvertent damage to the iris in cases with suboptimal pupil dilation.
我们描述了一种技术，该技术通过完整的5.0至6.0毫米连续环形撕囊将晶状体核移位，从而将超声乳化过程转移至囊袋外。然后将倒置的晶状体核放回后房，置于前囊上方的“囊上间隙”，在整个超声乳化手术过程中（无论是劈裂、切碎、手动预切碎还是传统雕刻）它都保持在该位置。囊上超声乳化的主要优点是效率更高，表现为乳化时间和能量减少。缺点包括在学习曲线的最初阶段可能出现轻度术后角膜水肿，以及在瞳孔扩张欠佳的情况下可能意外损伤虹膜。
