AIM:To compare the efficacy of phacoemulsification and phacoemulsification combined with improved goniosynechialysis for angle-closure glaucoma with cataract.

METHODS: Eighty-four patients of angle-closure glaucoma with cataract were randomly divided into two groups, one was given cataract phacoemulsification treatment, the other was given cataract phacoemulsification combined with goniosynechialysis. Intraocular pressure(IOP), best corrected visual acuity, anterior chamber depth, anterior chamber angle width and pupil size were measured before or after the operation.

RESULTS: All cases' IOP was reduced obviously after the operation, and there was a significant difference between the preoperation and postoperation(P<0.05). Eighty-three eyes were improved in visual acuity, 1 eye was not improved. Anterior chamber depth and anterior chamber angle width after the operation were increased compared with those before operation. Compared with the control group, visual acuity and central anterior chamber depth was no significant difference in the observation group. IOP was controlled more effectively in the observation group, and anterior chamber angle width was increased obviously.

CONCLUSION: Phacoemulsification combined with improved goniosynechialysis is an effective therapy for angle-closure glaucoma with cataract. it can effectively reduce IOP and increase anterior chamber angle width.
