方法：选取2015-06/2016-05在我院行白内障超声乳化吸除联合人工晶状体植入术的患者74例89眼，于术前及术后3mo测量患者眼压、中央前房深度(ACD)、房角开放距离(AOD500)和房角角度(ACA500)。

结果：术后3mo，眼压为11.34±2.38mmHg，较术前(12.60±2.51mmHg)有所降低，差异有统计学意义(P<0.05)； ACD为4.01±0.30mm，较术前(2.30±0.42mm)明显增厚，差异有统计学意义(P<0.05)； AOD500和ACA500分别为0.915±0.223mm和41.71°±6.55°，明显高于术前0.514±0.201mm和24.01°±8.43°，差异有统计学意义(P<0.05)； 眼压值与ACD、AOD500和ACA500呈负相关(r=-0.239、-0.211、-0.252，P<0.05)。

结论：超声乳化联合人工晶状体植入术可降低患者眼压，增加患者前房深度和房角宽度，从而对眼内房水循环起到积极作用。

METHODS: A total of 74 cases(89 eyes)with cataract phacoemulsification combined with intraocular lens implantation were selected from Jun. 2015 to May. 2016 in our hospital, measured preoperative and postoperative 3mo intraocular pressure, central anterior chamber depth(ACD), angle open distance(AOD500)and anterior chamber angle(ACA500).

RESULTS: Patients postoperative 3mo the intraocular pressure was 11.34±2.38mmHg, which was lower than that preoperative(P<0.05). Patients postoperative 3mo ACD was 4.01±0.30mm, was significantly thicker than preoperative(P<0.05). Patients postoperative 3mo AOD500 and ACA500 were 0.915±0.223 mm and 41.71°±6.55°, were significantly higher than preoperative, the difference was statistically significant(P<0.05). Intraocular pressure was negatively correlated with ACD, AOD500 and ACA500(r=-0.239, -0.211 and -0.252, P<0.05).

CONCLUSION: Phacoemulsification combined with intraocular lens implantation can reduce the intraocular pressure, increase the depth of anterior chamber and the width of chamber angle, so as to play a positive role inaqueous humor circulation.
