Posterior capsular opacification (PCO) is the most common complication that leads to vision loss after cataract surgery. It is classically divided into fibrotic type and regenerative type according to clinical manifestations or pathological mechanisms. The widely used technique for preventing PCO is to mechanically polish anterior and posterior capsules after an uneventful phacoemulsification surgery. However, the efficacy of polishing anterior capsules on prevention of PCO is debatable. It has been found that polishing anterior capsules has an inhibitory or no effect on fibrotic PCO, but a stimulating effect on regenerative PCO. Therefore, whether to polish anterior capsules is dependent on the condition of individual patients and the type of intraocular lenses. (Chin J Ophthalmol, 2021, 57: 492-494).
后发性白内障（PCO）是白内障患者术后视力下降最常见的并发症。PCO不论按照临床表现还是病理机制均可分为纤维型和再生型。目前临床最常用的预防PCO的技术为术中机械性晶状体前后囊膜抛光，但是否有效预防PCO一直存在分歧。进一步的研究发现晶状体前囊膜抛光对纤维型PCO有抑制作用或没有作用，而对再生型PCO很可能有促进作用。因此，是否行晶状体前囊膜抛光应该根据患者具体情况以及植入人工晶状体类型而定。（中华眼科杂志，2021，57：492-494）.
