Management Of Primary Angle-closure Glaucoma With Cataract By Phacoemulsification With Foldable Posterior Chamber Intraocular Lens Implantation

Objective : To 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.Methods:Collect 34 cases(41eyes) of PACG with cataract during January 2007 to January 2009,including 15 eyes of preclinical APACG,10 eyes of paroxysmal APACG, 16 eyes of CPACG.Visual acuity distributed from light perception to 0.6.Phacoemulsification and intraocular lens implantation were performed and patients were followed up for (6.9±2.0)months about visual acuity ,gonioscopy, anterior chamber depth. Results:In 41 eyes of PACG,visual acuity was corrected in 37 eyes(90.2%),including 30 eyes (73.1 %)with corrected visual acuity>0.5;In preclinical APACG group,postoperative IOP decreased (t=7.094,P<0.05);in paroxysmal APACG group, postoperative IOP decreased (t=3.495,P<0.01);in CPACG groups,postoperative IOP decreased (t=3.667,P<0.01);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 (P<0.05).In 41 eyes of PACG,visual acuity was corrected in 37 eyes(90.2%)including 30 eyes (73.1%)with corrected visual acuity>0.5. Condusion:It's safe and effective treat angle-closure glaucoma with cataract by phacoem -ulsification plus foldable IOL implantation.
