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。
AIM: To analyze the clinical curative effect and operation complications in the process of extracapsular extraction of cataract by phacoemulsification.
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.
