AIM: To evaluate the features and clinical outcomes of cataract extraction by phacoemulsification with intraocular lens implantation in primary angle-closure suspect(PACS), primary angle-closure(PAC)and primary angle-closure glaucoma(PACG)with cataract.

METHODS:Phacoemulsification with intraocular lens implantation was performed on 86 cases(86 eyes)diagnosed as PACS, PAC and PACG co-existing cataract from January to December 2012. All cases were followed up for 3 months to 1 year. Pre-operative and post-operative visual acuity, intraocular pressure(IOP), gonioscopy, ultrasound biomicroscopy(UBM), visual field and usage of anti-glaucomaous eye drops were recorded.

RESULTS:Zonular dialysis existed in 19 eyes(22%). The post-operative visual acuity improved in 84 eyes(98%). The post-operative visual acuity was <0.1 in 7 eyes(8%), 0.1-0.5 in 32 eyes(37%), 0.6-1.0 in 47 eyes(55%). There were 83 eyes(97%)with IOP between 10-15mmHg without any drug at the end of the follow-up period. The central anterior chamber was deepened and the anterior angle opened postoperatively at different extent.

CONCLUSION: PACS, PAC and PACG co-existing zonular dialysis is common. Phacoemulsification with IOL implantation can reduce IOP, deepen anterior chamber and open angle.
