We describe a case of radial extension and its management during femtosecond laser-assisted cataract surgery (FLACS) in a patient with intumescent cataracts. Radial extension was observed after injection of trypan blue into the anterior chamber. Management of the extension was achieved by separation of adhesions between the incomplete capsulotomy, along with manual completion at the areas of extensions. Careful observation during FLACS capsulotomy is advised in cases of intumescent cataracts due to the release of cortex into the anterior chamber which may interfere with the delivery of the laser treatment resulting in incomplete capsulotomy patterns. Furthermore, trypan blue staining is essential to identify possible incomplete capsulotomy patterns and extensions. The Argentinian flag sign may occur after femtosecond laser-assisted capsulotomy in cases of intumescent cataracts. Proper identification of incomplete capsulotomy patterns and radial extensions should be managed with careful manual completion of the capsulotomy.
我们描述了一例膨胀期白内障患者在飞秒激光辅助白内障手术（FLACS）期间出现放射状延伸及其处理情况。在前房注射台盼蓝后观察到放射状延伸。通过分离不完全撕囊之间的粘连以及在延伸区域手动完成撕囊来处理延伸情况。对于膨胀期白内障病例，建议在FLACS撕囊过程中仔细观察，因为皮质释放到前房可能会干扰激光治疗的进行，导致撕囊模式不完全。此外，台盼蓝染色对于识别可能的不完全撕囊模式和延伸至关重要。在膨胀期白内障病例中，飞秒激光辅助撕囊后可能会出现阿根廷国旗征。应通过仔细手动完成撕囊来处理不完全撕囊模式和放射状延伸的正确识别。
