The best corrected visual acuity(BCVA), intraocular pressure(IOP), refractive error, endothelial cell count(ECC), anterior segment parameters, including anterior chamber depth(ACD) and anterior chamber angle(ACA) were measured before and 1 mo after the laser posterior capsulotomy. RESULTS: In both groups, the BCVA improved significantly(P<0.001 for the modified round pattern group, P=0.001 for the cruciate pattern group); the IOP and ECC did not significantly change. The ACD significantly decreased(P<0.001 for both) and the ACA significantly increased(P=0.001 for the modified round pattern group and P=0.034 for the cruciate group). The extent of changes in these parameters was not significantly different between the groups.CONCLUSION: Modified round pattern Nd:YAG laser posterior capsulotomy is an effective and safe method for the treatment of PCO. This method significantly changes the ACD and ACA, but the change in refraction is not significant. Modified round pattern Nd:YAG laser posterior capsulotomy can be considered a good alternative procedure in patients with symptomatic PCO. 关 键 词：以后的 capsulotomy 修改圆模式 玻璃的海滨切 前面的片断参数
