摘要
目的观察老年性白内障透明角膜切口超声乳化术后眼压变化。方法回顾性分析273例(273只眼)老年性白内障患者,右眼131例,左眼142例,男性96例,女性177例,平均年龄(71±12)岁,均采用透明角膜切口,观察术后15 d、1、2、3个月和6个月的眼压情况。眼压变化的数据采用统计学的方法分析,P<0.05为检验水准。结果术前平均眼压为(14.18±3.4)mm Hg,术后眼压与术前相比平均眼压降低2.25 mm Hg,眼压的变化与人工晶状体厚度无关(P=0.12),眼压变化主要与前房深度的变化有关(P=0.002),术前眼压与前方深度呈负相关。年龄、性别和眼轴长度与眼压变化无明显相关(P=0.2~0.5)。结论透明角膜切口白内障超声乳化术后可有降低眼压的效果。
Objective To evaluate changes in intraocular pressure(IOP) after clear corneal phacoemulsification(CCP) in patients with age-related cataract.Methods A prospective study with 273 patients underwent cataract extraction by CCP.Intraocular pressure was examed on the 15th day,lst,2nd,3rd month and 6 months after surgery.Statistical Analysis:For statistical analysis,Epi Info was used to determine the statistical significance of changes in IOP.Results 96 male and 177 female were included with the mean age of 71±12 years.The mean IOP before surgery was 14.18 ± 3.4 mm Hg.These patients showed a mean decrease in IOP of 2.25 mm Hg(16%) compared to preoperative IOP.Change in IOP was not related to lens thickness(P = 0.12),but significantly correlated with the change in anterior chamber depth(ACD)(P=0.002).The postoperative IOP was inversely related to preoperative ACD(P=0.012).Age,sex and axial length were not significantly related to IOP reduction(P=0.2~0.5).Conclusion CCP was associated with a statistically significant reduction in IOP.CCP can be performed with the intent of achieving better IOP control.
