AIM:To observe the effectiveness and safety of phacoemulsification with intraocular lens (IOL) implantation or combined with trabeculectomy in patients with cataract and angle-closure glaucoma. METHODS:In 251 cases （279 eyes）with cataract and angle-closure glaucoma，208 eyes in which the wideness of the anterior chamber angle was NⅠ-NⅡ had been performed phacoemulsification and IOL implantation ；71 eyes in which the wideness of the anterior chamber angle was NⅢ-NⅣ had been performed phacoemulsification and IOL implantation combined with trabeculectomy. RESULTS: Followed up for 3 months，intraocular pressure kept normal in all 208 eyes in the group of phacoemulsification and IOL implantation；intraocular pressure kept normal in 68 eyes in the group of phacoemulsification and IOL implantation combined with trabeculectomy，intraocular pressure in 3 eyes was 20-25mmHg for 1 week after operation，and then was controlled to normal with 50g/L Betoptic. CONCLUSION:Phacoemulsification and intraocular lens implantation or combined with trabeculectomy is an effective and safe surgical technique with less complications for the cataract and angle-closure glaucoma.
