AIM: To explore the clinical effect of cataract phacoemulsification in eyes with filtered primary angle closure glaucoma(PACG).

METHODS: Forty-eight patients(48 eyes)with cataract with filtered PACG received phacoemulsification, and were followed up for 3-12mo to observe the visual acuity, intraocular pressure(IOP), and postoperative complications situation.

RESULTS: Postoperative visual acuity improved obviously, 85% patients reached to 0.3-0.8. All cases have normal IOP. There was no significant effect on postoperative IOP, which was within normal range. No serious complications happened.

CONCLUSION: Cataract phacoemulsification after anti-glaucoma surgery can significantly improve visual acuity, have no impact on IOP, filtering blebs and have fewer complications. It's safe and effective.
