方法：对4 350眼老年性、并发性和外伤性白内障患者进行巩膜隧道切口超声乳化联合人工晶状体植入术，总结分析术中及术后手术并发症发生情况及处理措施。术后随访3～24mo。

结果：顺利完成超声乳化术4 345眼(99.89%)，5眼术中改为ECCE+IOL术。 术后3mo时， 矫正视力≥0.5者4 050眼(93.10%)，0.1～0.4者290眼(6.67%)，<0.1者10眼(0.23%)。术中并发症：后囊膜破裂26眼(0.60%)，撕囊失败16眼(0.37%)。术后并发症：角膜水肿350眼(8.05%)，晶状体后囊膜混浊116眼(2.67%)，一过性高眼压31眼，眼内炎3眼。术中、术后并发症，经对症处理后有不同程度改善。

结论：白内障超声乳化人工晶状体植入术具有创伤小、恢复快、术后视力满意等优点，但是了解手术并发症原因，减少和避免并发症的发生以及采取措施正确处理并发症是手术成功的保障。术中并发症主要是后囊膜破裂，术后并发症主要是角膜水肿和后发性白内障。并发症的发生与术者的经验、技术熟练程度密切相关。

METHODS: Totally 4 350 cases of cataract were treated by sclera tunnel incision phacoemulsification cataract extraction, and the reason of the operation complications was analyzed. The patients were followed-up for 3-24 months.

RESULTS:Phacoemulsification was performed successfully on 4 345 eyes(99.89%), and 5 eyes were changed to extracapsular cataract extraction combined with intraocular lens(ECCE+IOL)implantation. 10 eyes(0.23%)attained corrected vision under 0.1; 290 eyes(6.67%)attained corrected vision of 0.1 to 0.4; 4 050 eyes(93.10%)attained corrected vision of 0.5 or better 3 months after operation. During the operations there were capsular rupture in 26 eyes(0.60%), defeated capsulorhexis in 16 eyes(0.37%), corneal endothelial edema 350 eyes(8.05%), posterior capsular opacification 116 eyes(2.67%), intraocular hypertension 31 eyes, entophthalmia in 3 eyes.

CONCLUSION: The extraction of cataract by phacoemulsification and embedding of artificial crystal may have less tissue damage, and vision recovers quickly. Though it is an effective method, understanding the reasons for operation complication and reducing the operation complication can ensure the success of operation.
