Abstract: Phacoemulsification (Phaco) in the treatment of patients with primary angle closure glaucoma (PACG), phacogenic glaucoma and primary open angle glaucoma (POAG) combined with cataract has a certain  effect of reducing  intraocular pressure and increasing the depth of the anterior chamber. For PACG patients with cataract, Phaco is more effective than laser peripheral iridotomy (LPI). The indications and intraocular pressure lowering effects of Phaco alone and Phaco+goniosynechialysis, Phaco+trabeculectomy and trabeculectomy were analyzed. The postoperative efficacy was different according to preoperative anterior chamber angle, intraocular pressure, the amount of intraocular pressure lowering medications and the damage of optic nerve in fundus.
