摘　　要：目的比较白内障超声乳化吸除术与小切口摘除术后患者黄斑厚度的变化。方法回顾分析接受两种手术方式摘除白内障的患者共48例(48只眼)(超声乳化组24例,小切口组24例)在术后第1、7、28天,进行相干光断层扫描(OCT)检查,分析黄斑厚度的变化情况。结果术后第1天,超声乳化组与小切口组患者的黄斑厚度分别是(189.3±31.2)μm、(190.7±24.1)μm,两者间差异不具有统计学意义(P=0.23);术后第7天,超声乳化组患者黄斑厚度值为(192.4±14.6)μm,小切口组患者的黄斑厚度为(199.2±34.5)μm,两者差异具有统计学意义(P=0.03);术后第28天,超声乳化组患者黄斑厚度(194.5±18.4)μm与小切口组患者黄斑厚度(203.9±20.8μm)的差异更明显(P=0.01)。结论小切口组患者相对于超声乳化组患者其黄斑厚度的增加更为明显,但所有患者黄斑厚度的改变均未引起明显的临床症状及黄斑水肿。Objective To compare macular thickness following phacoemulsification and manual small incision cataract surgery （MSICS）. Methods Prospective study was carried out with 48 eyes of 48 patients with senile cataract randomized into two groups,phacoemulsification and MSICS,by simple 1：1 randomization. Following surgery by either of the two methods,macular thickness was measured by optical coherence tomography （OCT） on the 1st,7th,28th postoperative day. Main outcome measure was postoperative macular thickness. Results On the first postoperative day,central mean thickness （CMT） in MSICS group was 190.7±24.1μm and that in phacoemulsification group was 189.3±31.2 μm,with no significant difference （P=0.23）. On the 7th day,CMT in MSICS group （199.2±34.5 μm） was signifi cantly （P= 0.03） more than that in phacoemulsification group （192.4±14.6 μm）. On the 28th day,CMT in MSICS group was 203.9±20.8 μm and that in phacoemulsification group was 194.5±18.4 μm,the difference being significant （P= 0.01）.Conclusion In spite of CMT in MSICS group was more than in phacoemulsification group,it was not showed that cystoid macular oedema and complication were happened.
