Abstract:  Posterior capsular opacification (PCO) is the most common complication after cataract operation. Recently, there are many researches interested in how to prevent PCO, such as the developments in the intraocular lens materials and designs, surgical methods such as anterior capsule polishing, posterior capsulorhexis with anterior vitrectomy, implanting capsular tension ring (CTR) or capsular adhesion-preventing ring (CAPR). However, the most of these preventing methods are controversial, the most action mechanisms are still unclear, and the long time effects are still uncertain.  （Ophthalmol CHN, 2014, 23: 76-79)
