Abstract: Posterior capsular opacification (PCO) is one of the common complications after phacoemulsification. Modern cataract surgery technology has significantly reduced the occurrence of this complication, with the improvement of modern surgical technology and intraocular lens materials, making the rate of YAG laser posterior capsulotomy is declining. Capsular membrane polishing, whether instruments, water flow polishing or negative pressure polishing can effectively remove the fiber stent on the posterior capsule surface and the detached epithelial cells, and can effectively prevent PCO. In patients with adequate anterior and posterior capsule polishing, the incidence of postoperative PCO is usually reduced.

Key words: cataract/surgery, posterior capsule opacification, capsule polishing
