摘　　要：目的探讨白内障超声乳化吸出手术对黄斑中心小凹厚度的影响。方法选取64例单纯性老年性白内障患者96眼,对患眼行常规白内障超声乳化吸出+人工晶体植入术,于术前、术后1 d、1周2、周四个时间段分别应用OCT黄斑部扫描程序对术眼行黄斑中心小凹厚度测量,通过配对t检验进行统计学处理,分析术眼术前及术后各时段黄斑部厚度的变化。结果 OCT扫描显示,无术眼发生黄斑囊样水肿,测得96例术眼黄斑中心凹的厚度均值:术前为176.101μm,术后1 d为176.554μm,术后1周为176.502μm,术后2周为179.456μm,将术前与术后1 d、术后1周、术后2周四组黄斑中心小凹厚度值配对t检验,P值均>0.05,差异无统计学意义。即术后1 d、术后1周、术后2周,黄斑中心小凹厚度值分别与术前相比差异无统计学意义。结论 OCT是检测黄斑厚度的有力工具之一,常规白内障超声乳化术后,患眼术后1 d、1周、2周黄斑中心小凹厚度与术前相比差异无统计学意义。Objective To detect the changes of macular thickness following uncomplicated phacoemulsification of senile cataract by optical coherence tomography（OCT）. Methods 96 eyes with senile cataract from 64 patients were studied, As for uncomplicated phacoemulsification and IOL implantation, all 96 eyes were examined by OCT to detect changes of foveola thickness in the preoperative period, postoperative 1 d, postoperative 1 week, and postoperative 2 week respectively. A paired t test was also performed to analyze the data and examine changes of foveola thickness in each of the four periods, so as to evaluate the impact of phacoemulsification on foveola thickness. Results No surgery-induced occurrence of cystoids macular edema had been detected by OCT. 96 eyes were examined by OCT fordetecting changes of foveola thickness after uncomplicated phacoemulsification on senile cataract,which turned out as 176. 101 μm preoperatively, 176. 554 μm on the first day after operation, 176. 502 μm in the first week after operation, 179.456 μm in the second week after operation. Data comparison of the preoperative and postoperative periods were found no significant difference in terms of foveola thickness （ P 〉 0.05 ）. Conclusion OCT was one of the most powerful tools for measuring foveola thickness. It showed that after uncomplicated phacoemulsification, there was no increase of foveola thickness or significant fluctuations in visual acuity in the ensuing 2 weeks.
