摘　　要：目的比较小切口白内障手术劈核与不劈核两种术式治疗白内障的疗效。方法选取2014年3月至2015年9月在仙桃市第一人民医院治疗的白内障患者125例(146眼)按照随机抽签法分为两组。观察组60例(75眼)行劈核的小切口白内障手术;对照组65例(71眼)行不劈核的小切口白内障手术。比较观察两组术后的视力、角膜散光、手术时间及并发症等。结果术后1周两组视力差异有统计学意义(Z=-2.078,P<0.05),术后1个月、3个月两组视力差异均无统计学意义(Z=-0.960、-0.743,均P>0.05)。术后1周、1个月观察组和对照组角膜散光差异均有统计学意义[(1.33±0.45)D比(1.52±0.49)D,(1.03±0.42)D比(1.18±0.44)D,t=2.442、2.108,均P<0.05)],术后3个月时两组角膜散光差异无统计学意义(t=0.432,P>0.05)。观察组与对照组手术时间差异无统计学意义[(11.28±2.32)min比(11.87±2.52)min,t=1.473,P>0.05]。两组各发生后囊破裂1例,但均未发生晶状体核脱入玻璃体腔、脉络膜下爆发性出血或角膜内皮失代偿等严重并发症。结论采用劈核的小切口白内障手术对比不劈核的小切口白内障手术具有术后早期视力恢复快和角膜散光小等优点。因此,劈核的小切口白内障手术值得临床推广与应用。Objective To compare efficacy of small incision cataract surgery whether combined with nucleus chopping or not in the treatment of cataract. Methods From March 2014 to September 2015, 125 cases of age-related cataract(146 eyes) in the the First People′s Hospital of Xiantao were divided into 60 cases(75 eyes) of observation group and 65 cases(71 eyes) of control group by method of random sampling.The observation group accepted small incision cataract surgery combined with chopping nucleus.The control group only underwent small incision cataract surgery.The postoperative visual acuity, corneal astigmatism and operation time, and complications and so on in the two groups were compared. Results There was statistically significant difference in postoperative visual acuity after 1 week between the two groups(Z=-2.078, P<0.05), but there was no statistically significant difference in postoperative visual acuity after 1 month or 3 months between the two groups(Z=-0.960, -0.743, all P>0.05). The postoperative corneal astigmatism after 1 week or 1 month between the observation group and the control group had statistically significant differences[(1.33±0.45)D vs.(1.52±0.49)D, (1.03±0.42)D vs.(1.18±0.44)D, t=2.442, 2.108, all P<0.05)], but there was no statistically significant difference in postoperative corneal astigmatism after 3 months between the two groups(t=0.432, P>0.05). There was no statistically significant difference in the operation time between the observation group and the control group[(11.28±2.32)min vs.(11.87±2.52)min, t=1.473, P>0.05]. One case of posterior capsular rupture occurred in the two groups, respectively.But serious complications such as lens nucleus escaped into vitreous cavity, explosive haemorrhage from the choroid or corneal endothelial decompensated had not been found. Conclusion The small incision cataract surgery combined with nucleus chopping has advantages in acquiring fast visual rehabilitation acuity in the early stage after operation, lower corneal astigmatism compared to that
