目的:探讨手法小切口白内障术(MSICS)和超声乳化(Phaco)白内障摘除术对白内障合并非增生期糖尿病性视网膜病变(nonproliferative diabetic retinopathy,NPDR)患者散瞳后瞳孔直径的影响。方法:前瞻性研究,选取核硬度达到III级(Emery法)的白内障合并NPDR患者45例60眼,分为MSICS组和Phaco组,每组30眼。白内障手术前后均采用复方托吡卡胺眼药水给予患眼散瞳,测量散瞳后瞳孔直径,两组术前及术后3mo的散瞳后的瞳孔直径进行比较。结果:MSICS组散瞳后瞳孔直径术前为6.23±0.83mm,Phaco组散瞳后瞳孔直径术前为6.26±0.85mm,两组差异无统计学意义(P>0.05)。MSICS组术前术后散瞳后瞳孔直径差值为0.11±0.094mm,差异有统计学意义(P<0.01);Phaco组术前术后散瞳后瞳孔直径差值为0.17±0.119mm,差异有统计学意义(P<0.01)。MSICS组和Phaco组之间术前术后散瞳后瞳孔直径差值的差异有统计学意义(P<0.05)。结论:白内障核硬度达到III级合并非增生期糖尿病性视网膜病变患者行MSICS和Phaco均可使散瞳后瞳孔直径变小,Phaco术可能对散瞳后瞳孔直径的影响更明显。

AIM:To investigate the influence to dilated pupil’s diameter of cataract patients with nonprohferative diabetic retinopathy (NPDR) by manual small incision cataract surgery (MSICS) and phacoemulsification(Phaco).METHODS:Pilot study.Sixty eyes of cataract patients with NPDR were divided into two groups,MSICS group of 30 eyes and Phaco group of 30 eyes.The pupil was dilated by Compound Tropicamide.The diameter of dilated pupil was compared before and after the cataract surgery.RESULTS:Before surgery,the dilated pupil’s diameter of MSICS group was 6.23±0.83mm,and Phaco group was 6.26±0.85mm.There was no significant difference between the two groups(P>0.05).Before and after the surgery,the difference of the dilated pupil’s diameter of MSICS group was 0.11±0.094mm,Phaco group was 0.17±0.119mm.The difference was significant(P<0.01).There was significant difference between the MSICS group and Phaco group in those above(P<0.05).CONCLUSION:Both MSICS and Phaco can reduce the diameter of dilated pupil of the cataract patients with NPDR.The phacoemulsification seems to reduce more.
