方法：回顾性分析2012-02/2013-02在我院行白内障超声乳化加IOL植入术的连续病例843例1042眼。正常眼轴组(21～24mm)853眼，高度轴性近视组(≥26mm)189眼。对比分析两组的眼内并发症，包括玻璃体脱失，后囊膜破裂，晶状体核掉入玻璃体腔和IOL位置异常。

结果：年龄在两个组中都是眼内并发症的风险因素，年龄的增长与眼内并发症的发生呈正相关，眼轴长度与眼内并发症的发生呈正相关，尤其对于后囊膜破裂和玻璃体脱失两个并发症。

结论：此项研究结果提示，年龄和眼轴长度是白内障超声乳化手术并发症发生的两个风险因素，了解这些风险并提前做好准备可能会降低并发症的发生。

METHODS: A retrospective review of 843 consecutive patients(1 042 eyes)of cataract extraction with phacoemulsification and IOL implantation in our hospital from February 2012 to February 2013 was performed. The patients were divided into two groups according to the axial length: 853 eyes were in normal axis group(21-24mm)and 189 eyes were in high axial myopia group(≥26mm). The two groups were compared regarding surgical complications, such as vitreous loss, posterior capsular rupture, nucleolus drop, and abnormal location of IOL.

RESULTS: Age was a risk factor in both groups. There was positive correlation between age and surgical complications, and between axial length and surgical complications, especially for complications with posterior capsular rupture and vitreous loss.

CONCLUSION: As the results illustrate, in this survey, age and high axial lengthare statistically significant risk factors for incidence of complications of phacoemulsification. Anticipation of these complications and also preparation and prophylactic measures may decrease incidence of these complications.
