方法：选择我院149例189眼白内障手术患者，其中82例104眼白内障患者在进行白内障超声乳化及人工晶状体植入术中运用抛光器进行后囊膜抛光处理，选择同期67例85眼未行后囊膜抛光患者进行对照。

结果：术后6mo，抛光组后囊膜混浊发生11眼(10.6%)，对照组后囊膜混浊发生23眼(27.1%)。两组比较有显著差异。术后12mo，抛光组后囊膜抛光组混浊发生17眼(16.3%)，而对照组术后后囊膜混浊发生31眼(36.5%)。对照组显著高于抛光组。术后抛光组和未抛光组视力检查发现，1wk时两组之间无明显差异，而术后6mo和12mo时差异具有统计学意义(P<0.05)。

结论：白内障超声乳化术中使用抛光器行后囊膜抛光安全有效，明显减少术后后囊膜混浊，能更好的提高患者视力。

METHODS: Totally 149 cataract patients including 82 cases(104 eyes )with phacoemulsification and intraocular lens implantation after posterior capsule polishing treatment by polishing device, and 67 cases(85 eyes )without posterior capsule polishing in phacoemulsification and intraocular lens implantation were recruited at the same period in this study.

RESULTS: Totally 11 eyes(10.6%)occurred PCO in polishing group and 23 eyes(27.1%)occurred PCO in control group 6 months after operation. There was significant difference between two groups. And 17 eyes(16.3%)occurred PCO in polishing group and 31 eyes(36.5%)occurred PCO in control group 12 months after operation. The control group was significantly higher than that of polishing group concerning PCO. The vision of this two group patients had no significant differences 1 week after operation, but there was significant difference 6 and 12 months after operation(P< 0.05).

CONCLUSION: The results showed that posterior capsule polishing in phacoemulsification is safe and effective. It can significantly reduce postoperative PCO and improve visual acuity.
