Objective To determine the difference of posterior capsular opacification (PCO) Postroperation of phacoemulsification with intraocular lens (IOL) implantation between cataract with axial high myopia and senile cataract.

Analysis of related factors of posterior capsular opacification;

Q-switch Nd:YAG Laser posterior capsulotomy for treatment of posterior capsular opacification;

Inhibition of posterior capsular opacification by all-trans retinoic acid;

Establishing the model of posterior capsule opacification in rats;

Recent advances in gene therapies for posterior capsule opacification after cataract surgery;

Experimental study on using arsenic trioxide in hydrodissection to inhibit the posterior capsule opacification and its intraocular toxicity in rabbit;
