ObjectiveTo investigate the clinical effect of phacoemulsification combined with goniosynechiolysis in treatment of angle-closure glaucoma.Methods163 cases of angle-closure glaucoma with cataract were divided into observed group (86 cases) and control group (87 cases).The observed group was treated with phacoemulsification cataract extraction, artificial crystalline implantation and goniosynechiolysis, while the control group was treated with compound trabeculectomy.The vision, intraocular pressure and chamber depth after surgeries in the two groups were compared.ResultsThe vision in observed group was enhanced distinctly after surgery,which was significantly better than the control group(P ＜0.05).The intraocular pressure in 2 weeks of observed group after surgery was significantly better than the control group(P ＜ 0.01).Moreover the anterior chamber depth and chamber angle of observed group was better than the control group after operation(P ＜ 0.05).ConclusionThe treatment of phacoemulsification combined with goniosynechiolysis for angle-closure glaucoma had good clinical effect.
