Two cases of limited (nonexpulsive) acute intraoperative suprachoroidal hemorrhage (AISH) were identified in a consecutive series of 3,096 cataract surgeries accomplished by capsular bag phacoemulsification--an incidence of 0.06%. This is lower than that reported by me in 1986 when I was using iris plane phacoemulsification (0.81%). I believe the reduction is the result of decreased anatomical distortion from reducing the number and amplitude of intraocular pressure swings experienced by the globe during surgery. The pressure swings result from technique-mandated oscillations in infusion and aspiration dynamics, which are greater in number and amplitude in the iris plane technique.
在连续进行的3096例采用囊袋内超声乳化白内障吸除术的白内障手术中，发现了2例局限性（非扩展性）急性术中脉络膜上腔出血（AISH），发生率为0.06%。这低于我在1986年使用虹膜平面超声乳化术时报告的发生率（0.81%）。我认为发生率降低是由于手术过程中眼球经历的眼内压波动的数量和幅度减少，从而减少了解剖结构的扭曲。压力波动是由技术要求的灌注和抽吸动力学振荡引起的，在虹膜平面技术中，这种振荡的数量和幅度更大。
