AIM:To investigate the surgery effect of phacoemulsification for primary angle-closure glaucoma(PACG) complicated with cataract surgery.METHODS:PACG complicated with cataract were 32 eyes, of which the acute phase of 28 eyes performed phacoemulsification, chronic phase of 4 eyes performed phacoemulsification combined with trabeculectomy.RESULTS:At postoperative 1 day, 9 eyes appeared corneal endothelial linear ruffled, 5 eyes occurred corneal stromal layer mild edema, turbidity cornea, which regressed at postoperative 2-4 days. Corneal restored transparent, causing inflammation cell + to + +. After the anti-inflammatory treatment for 1 week, inflammatory cells in the anterior disappeared. After 1 week follow-up, the acute phase of 28 eyes, intraocular pressure were 10-20mmHg, chronic phase of 4 eyes, intraocular pressure were 7-9mmHg. At postoperative two weeks of follow-up, all patients'' intraocular pressure were 10-20mmHg. Visual acuity of all the patients improved to varying degrees. CONCLUSION:Phacoemulsification combined with IOL implantation for the treatment of PACG complicated with cataract is a safe, effective, change numerous for brief choice, which avoids to re-performing the cataract surgery after pure glaucoma surgery. 
