Abstract：Objective To analyze clinical efficacy of applying a capsular tension ring in the treatment of acute angle-closure glaucoma secondary to abnormalities of the lens suspensory ligament.Methods A prospective study was conducted at Yantai Affiliated Hospital of Binzhou Medical University from December 2023 to July 2024 involving 40 patients with acute angle-closure glaucoma secondary to abnormalities of the lens suspensory ligament.The patients were randomly divided into two groups,with 20 cases in each group.Group A underwent capsular tension ring implantation,while Group B did not.Both groups underwent phacoemulsification cataract extraction combined with intraocular lens implantation and anterior chamber angle microscopy-assisted angle separation.The intraocular pressure,best corrected visual acuity,the tilt and eccentricity of the intraocular lens,and the openness of the anterior chamber angle at 1 week,1 month,and 6 months after surgery in the two groups were compared.Results The intraocular pressure of both groups decreased after the operation,and the difference was statistically significant compared with that before the operation(P=0.001).There was no statistically significant difference between the two groups in the comparison(P＞0.05);the visual acuity of both groups improved after the operation,and the difference was statistically significant compared with that before the operation(P＜0.05),and the difference between the two groups in the comparison was also statistically significant(P＜0.05);the eccentricity and tilt degree of the intraocular lenses in both groups were statistically significantly different(P＜0.001,P＜0.001);there was no statistically significant difference in the comparison of the trabecular iris angle(TIA250)between the two groups(P＞0.05).Conclusion The combined use of phacoemulsification and aspiration for cataract removal along with anterior chamber angle separation in the treatment of acute angle-closure glaucoma secondary to abnormalities of the lens suspensory ligament can effectively control intraocular pressure,improve vision,and in combination with the implantation of a capsular tension ring,it can reduce the postoperative eccentricity and tilt of the intraocular lens,ensuring the effective position of the postoperative intraocular lens.
