AIM:To evaluate the clinical outcomes and affected factors of prognosis of cataract extraction by phacoemulsification with intraocular lens implantation in eyes with primary angle-closure glaucoma(PACG)and co-existing cataract.

METHODS: Totally 60 cases(70 eyes)of PACG with cataract, including 43 eyes with acute primary angle-closure glaucoma(APACG), 27 eyes of chronic primary angle-closure glaucoma(CPACG). The main outcome measures included: visual acuity, intraocular pressure, gonioscopy, depth of anterior chamber(ACD). Patients were examined 6 months after surgery.

RESULTS: After phacoemulsification, visual acuity was improved(P<0.05), postoperative mean IOP was decreased(P<0.01), part of anterior chamber was widened(P<0.01). The depth of anterior chamber(ACD)was deepen(P<0.01).

CONCLUSION:Phacoemulsification is more effective for acute APACG than for CPACG.
