表麻下小切口非超声乳化白内障手术并发症探讨

目的 观察表麻下小切口非超声乳化白内障手术术中、术后并发症，对其进行分析并提出处理意见。方法 102例(102只眼)白内障，术中表面麻醉后，采用圈垫式劈核技术，手法碎核，进行小切口非超声乳化白内障摘除并人工晶状体植人术。结果 术中：虹膜脱出12只眼，虹膜根部离断1只眼，晶状体后囊破裂7只眼。术后：角膜内皮条样浑浊30只眼，片状浑浊10只眼，前房纤维素样渗出10只眼，继发青光眼1只眼。结论 表麻下小切口非超声乳化白内障手术避免了球周、球后麻醉带来的一系列并发症。对晶状体核的处理较关键，亦是易产生并发症的步骤。

Complications in small incision non-phacoemulsification cataract surgery with topical anesthesia

Objective To observe the complications caused by small incision non-phacoemulsification cataract operation with topical anesthesia, analyze the results and give some advice about the disposal. Methods 102 patients were observed. After topical anesthesia, cataract extraction with IOL implantation in small incision were going on based on chop technique with lens loop pad. Results Intraoperative complications included iris prolapse in 12 eyes, iridodialysis in 1 eye and posterior capsule rupture in 7 eyes, and some postoperative complications, including 30 strip shaped opacity in corneal endothelium, 10 sheet shaped opacity in corneal endothelium, 10 anterior chamber fribrinous exudates and 1 secondary glaucoma were found. Conclusion A lot of complications what caused by retrobulbar anesthesia and peribulbar anesthesia can be avoid with topical anesthesia in small incision non-phacoemulsification cataract surgery. It is very important to treat the lens nucleus accurately and this process would be more likely to bring on complications.
