方法：对54眼硬核白内障患者进行小切口手法劈核及人工晶状体植入，观察手术前后裸眼视力、矫正视力、眼前节、眼底及并发症情况。

结果：术前裸眼视力(LogMAR)1.095±0.171，矫正视力(LogMAR)0.994±0.158。术后1wk裸眼视力(LogMAR)0.321±0.214，矫正视力(LogMAR)0.276±0.179。手术前后裸眼视力及矫正视力比较均具有统计学意义(t=27.052、29.211，P<0.01)； 术前角膜散光平均值为0.93±0.34D，术后3mo为 0.95±0.29D，手术前后比较差异无统计学意义(t=1.048，P>0.05)； 全组病例无严重并发症发生。

结论：小切口手法碎核技术在硬核白内障处理中具有优势，安全有效。

METHODS: Fifty-four patients(54 eyes)were performed with small incision manual nucleofragmentation and intraocular lens implantation. Uncorrected-visual acuity, corrected-visual acuity and astigmatism were measured before and after surgery. Anterior segment of eye, retina, surgical complications were observed.

RESULTS: Preoperative uncorrected vision(LogMAR)was 1.095±0.171, corrected vision(LogMAR)was 0.994±0.158. Postoperative uncorrected vision(LogMAR)was 0.321±0.214 and corrected vision(LogMAR)was 0.276±0.179 at 1wk after operation. Both had statistical significance compared with uncorrected vision(LogMAR)(t=27.052, P<0.01)and corrected vision(LogMAR)(t=29.211, P<0.01)after cataract operation. Average preoprative corneal astigmatism was 0.93±0.34D, average postoprative astigmatism was 0.95±0.29D at 3mo, there was no statistical significance of astigmatism before and after surgery(t=1.048, P>0.05). No severe complications occurred in all cases.

CONCLUSION: The technology of small incision manual nuncleofragmentation in hard-nucleus cataract is proved to be safe and effective.
