目的:探讨后囊膜连续环形撕囊(PCCC)在白内障手术中的意义。方法:回顾性研究分析2003-01/2010-12在我院行白内障超声乳化手术、术中后囊膜破裂非计划行后囊膜连续环形撕囊的病例,定期观察最佳矫正视力、角膜内皮计数、眼压、角膜水肿情况、前房Tyndall’s征、瞳孔及人工晶状体位置情况。结果:术后1mo,PCCC组与未行PCCC组的最佳矫正视力0.8以上的差异有统计学意义;术后1mo,PCCC组与未行PCCC组的角膜内皮计数、眼压、角膜水肿情况、前房Tyndall’s征的差异均无统计学意义。结论:后囊膜破裂后在可行PCCC的病例中可以更有效地减少术后并发症,使患者得到更稳定舒适的视觉效果。

AIM:To study the effect of posterior continuous curvilinear capsulorhexis(PCCC) in phacoemulsification and intraocular lens implantation·METHODS:Totally 72 cases(72 eyes) undergoing phacoemulsification and intraocular lens implantation from January 2003 to December 2010 were analyzed.PCCC were used in the intraoperative posterior capsule tears.After surgery,the best-corrected visual acuity,the count of corneal endothelial,intraocular pressure,corneal edema,anterior chamber Tyndall’s sign,pupil and position of the intraocular lens were analyzed·RESULTS:One month after surgery,comparision of the best-corrected visual acuity beyond 0.8 between the cases which used PCCC and the cases which didn’t use PCCC was statistical significant.The difference of the count of corneal endothelial,intraocular pressure,corneal edema,anterior chamber Tyndall’s sign between the cases which used PCCC and the cases which didn’t use PCCC wasn’t statistical significant·CONCLUSION: PCCC can be more effective in reducing postoperative complications in the case which can use PCCC,and the patients can attain a more stable and comfortable visual acuity.
