OBJECTIVETo evaluate the efficacy and safety of phacoemulsification with foldable posterior chamber intraocular lens(PC-IOL) implantation in the management of acute or chronic primary angle-closure glaucoma(APACG or CPACG) with cataract.

METHODSTwenty-six cases(28 eyes) with simple cataract and 60 cases(70 eyes)of PACG with cataract, including 14 eyes of preclinical APACG, 29 eyes of paroxysmal APACG, 27 eyes of CPACG. Visual acuity distributed from hand movement to 0.8. Phacoemulsification and intraocular lens implantation were performed and patients were followed up for(8.5+/-4.5) months.

RESULTIn simple cataract group, postoperative IOP did not decrease(t=1.9201, P>0.05); in preclinical APACG group, postoperative IOP decreased (t=3.9910, P<0.01); in paroxysmal APACG group, postoperative IOP decreased (t=4.7441, P<0.01); in CPACG groups, postoperative IOP decreased (t=4.4976, P<0.01). In APACG and CPACG groups postoperative antiglaucoma medication reduced. In APACG and CPACG groups, angle of anterior chamber was widen. Preoperative central and peripheral ACD of APACG and CPACG were much less than those of postoperative. In 56 eyes of PACG, visual acuity was corrected in 48 eyes(85.7%) including 28 eyes(50%) with corrected visual acuity>0.5.

CONCLUSIONThe phacoemulsification with foldable posterior chamber intraocular lens implantation is beneficial for PACG with cataract, and the curative efficacy of APACG is better than that of CPACG.
