Abstract
Objective To evaluate the effeicacy of phacoemulsification combined with intracapsular tension ring implantation in the treatment of angle closure glaucoma (ACG) caused by abnormal suspension ligament (ASL). Methods The data of 64 eyes of 60 cases with ACG caused by ASL from Jun. 2016 to Jun. 2018 in this hospital were analyzed retrospectively.According to the random distribution, all patients were divided into two groups, with 30 cases in each group.Group A underwent phacoemulsification combined with intraocular lens implantation, group B underwent phacoemulsification combined with intracapsular tension ring implantation. Results The intraocular pressure at 1 day and 1 month after operation in the two groups were lower than that before operation, and that of group B was lower than that of group A. The difference was statistically significant (P<0.001). BCVA after operation was higher than that before operation in two groups, BCVA in group B was better than that in group A, and the difference was statistically significant (P<0.001). The central anterior chamber depth of both groups was deeper than that before operation, and that of group B was significantly greater than that of group A (P<0.001). The difference of complication rates was not statistically significant between the two groups (P=0.688). Conclusion Phacoemulsification combined with intracapsular tension ring implantation in the treatment of ACG caused by ASL is effective, which can effectively ameliorate the intraocular pressure, BCVA and central anterior chamber depth.
