方法：将42例硬核性白内障患者分为观察组和对照组，观察组患者选择手法碎核小切口白内障摘除术，对照组患者采用超声乳化白内障摘除术。比较两组患者术后1d； 1wk； 1，3mo矫正视力效果及治疗前后角膜散光，观察并比较两组患者术中及术后并发症发生情况。

结果：术后1d； 1wk； 1，3mo，两组患者矫正视力0.5～1.0患者的比例间差异均无显著性(P>0.05)。术后1d及术后1wk，观察组患者角膜散光高于对照组，差异具有显著性(P<0.05)。术后1mo及术后3mo，两组患者角膜散光间无统计学差异(P>0.05)。术中，对照组患者发生后囊膜破裂的比例显著高于观察组； 术后，对照组患者发生角膜水肿的比例显著高于观察组，差异均具有显著性(P<0.05)。

结论：手法碎核小切口白内障摘除术治疗硬核性白内障效果可靠，并发症少。

METHODS: Totally 42 patients with hard nuclear cataract were divided into observation group and control group, the observation group patients chosen broken nuclear small incision cataract surgery, the control group chosen phacoemulsification cataract surgery. Vision correction, corneal astigmatism effect after 1 day, 1 week, 1 month and 3 months and postoperative complications of two groups were observed and compared.

RESULTS: After 1 day, 1 week, 1 month and 3 months, the difference of the proportion of patients corrected visual acuity 0.5-1.0 had no significant significance(P>0.05). Postoperative 1 day and 1 week, the observation group patients with corneal astigmatism higher than that in the control group, the difference was significant(P<0.05). After 1 month and 3 months, there were no significant difference between the two groups of patients with corneal astigmatism(P>0.05). Sac membrane rupture in the control group was significantly higher than the observation group, the ratio of postoperative corneal edema in the control group were significantly higher than the observation group, the differences were statistically significant(P<0.05).

CONCLUSION: Broken nuclear small incision cataract surgery has good effect and few complications.
