PURPOSE
We describe a case of posterior capsule rupture during femtosecond laser-assisted cataract surgery (FLACS) due to direct exposure of the posterior capsule to the laser beam.
OBSERVATIONS
A 47-year-old man underwent FLACS for anterior capsule opacity. The CATALYS® system automatically detected the posterior capsule from the optical coherence tomography (OCT) images, after which the operator manually adjusted the line of posterior capsule. Femtosecond laser irradiation was presumed to be completed successfully. However, upon insertion of a phaco-tip, the diced nucleus of the lens dropped into the vitreous chamber. Reviewing intraoperative OCT images of the treatment summary to check the area irradiated by laser, an arc-shaped high-intensity area was observed behind the posterior capsule. This high-intensity was misinterpreted as the posterior capsule, which led to error in application of laser beam during procedure.
CONCLUSIONS AND IMPORTANCE
Comparison of data acquired using different imaging modalities could enable correct identification of the posterior capsule.
目的
我们描述了一例在飞秒激光辅助白内障手术（FLACS）过程中后囊破裂的病例，原因是后囊直接暴露于激光束下。
观察结果
一名47岁男性因前囊混浊接受了FLACS手术。CATALYS®系统通过光学相干断层扫描（OCT）图像自动检测到后囊，之后操作员手动调整后囊线。飞秒激光照射被认为成功完成。然而，在插入超声乳化头时，晶状体切碎的核掉入玻璃体腔。回顾治疗总结的术中OCT图像以检查激光照射区域时，在后囊后方观察到一个弧形高强度区域。这个高强度区域被误认作后囊，导致手术过程中激光束应用错误。
结论与重要性
比较使用不同成像方式获取的数据可以正确识别后囊。
