方法：对我院2006-01/2012-10完成的白内障超声乳化工晶状体植入术1 258例1 318眼临床资料进行回顾分析。

结果：术后发生高眼压共54眼，发生率为4.10%。术后眼压升高的幅度为22～60mmHg，大多数患者出现高眼压的时间为术后2～24h。54眼中先天性白内障1眼，外伤性白内障2眼，合并糖尿病15眼，合并高血压病12眼，陈旧性色素膜炎2眼，玻璃体切割术后1眼，合并高度近视11眼，未合并全身疾病的白内障10眼。裂隙灯观察高眼压患者可见部分皮质残留以及黏弹剂残留或晶状体后囊膜破裂玻璃体溢入前房或严重的炎症反应。

结论：黏弹剂残留和炎症反应是引起术后高眼压的主要原因，合并有糖尿病、高度近视、陈旧性色素膜炎、眼外伤等疾病的白内障患者更容易出现术后高眼压。

METHODS: Totally 1 258 cases(1 318 eyes)of cataract treated with phacoemulsification and intraocular lens implantation were retrospectively analyzed in our hospital from January 2006 to October 2012.

RESULTS: Among the 1 318 eyes, IOP occurred in 54 eyes(about 4.10%). The IOP reached the peak mostly 2 to 4 hours after the surgery, up to 22-60mmHg. One eye with congenital cataract; 2 eyes with traumatic cataract; 15 eyes with diabetes; 12 eyes with hypertension; 2 eyes with chronic pigment meningitis; 1 eye after vitrectomy; 11 eyes with high myopia; 10 eyes with unconsolidated systemic disease. Part of the cortical residual and the viscoelastic agent residue or crystal posterior capsular rupture vitreous overflowed into the anterior chamber or severe inflammatory reaction was observed through slit lamp in high IOP patients.

CONCLUSION: Viscoelastic agent residue and inflammation is the main reason of IOP. With diabetes, high myopia, chronic pigment meningitis, ocular trauma of disease such as cataract patients are more prone to IOP.
