〔Abstract〕 Objective To explore the clinical efficacy of phacoemulsification and surgery on cataract combined with angleclosure glaucoma. Methods 62 patients with cataract and angle closure glaucoma treated in Dongguan Humen Hospital of Traditional Chinese Medicine from October 2018 to February 2020 were selected as study subjects by digital randomized table, including 31 cases each of the control group and observation group (31 eyes). The control group was treated with traditional surgery, and the observation group used phacoemulsification to compare the treatment effect of the two groups. Results The total treatment efficiency of the patients in the observation group was significantly higher than that in the control group, the difference was statistical significant (P < 0.05); After treatment, intraocular pressure in both groups were lower than those before treatment, and intraocular pressure in the observation group was lower than that in the control group, the differences were statistically significant (P < 0.05); After treatment, the visual acuity of the two groups were significantly improved compared with those before treatment, and the visual acuity of the observation group was better than that of the control group, the differences were statistically significant (P < 0.05); After treatment, the anterior chamber depth in both groups were significantly increased compared with those before treatment, and the anterior chamber depth in the observation group was significantly greater than that in the control group, with statistical significances (P < 0.05). Conclusion In the clinical treatment of cataract with angle-closure glaucoma, phacoemulsification combined with surgery is more ideal, which can reduce the intraocular pressure of patients, increase the depth of anterior chamber, and improve the visual acuity level of patients.
