Clinical Efficacy of Combined Surgery in Patients with Glaucoma Complicated with Cataract and Factors Affecting Postoperative Refractive Error
Objective To investigate the clinical efficacy of combined surgery in patients with glaucoma complicated with cataract and to analyze the influencing factors of postoperative refractive error.Methods A total of 78 patients with glaucoma and cataract(78 eyes)admitted to People's Hospital of Henan Province from January 2021 to January 2023 were enrolled,and all patients were treated with phacoemulsification combined with trabeculectomy,and the average intraocular pressure,visual acuity level,best-corrected visual acuity(BCVA),refractive error,axial length(AL),anterior chamber depth(ACD),lens thickness,lens arch height(LV),corneal curvature(K)value,central corneal thickness and white-to-white distance were detected.Clinical data of patients were collected,and the factors affecting postoperative refractive error were analyzed by univariate and multivariate logistic regression.Results The mean intraocular pressure of patients with glaucoma and cataract was lower than that before surgery(P＜0.05),and the average visual acuity and BCVA were higher than that before surgery(P＜0.05).Three months after surgery,the refractive error of 41 eyes(52.56％),12 eyes(15.38％)of myopia and no refractive error of 25 eyes(32.05％)and absolute refractive error of(0.52±0.06)D in patients with glaucoma and cataract were present.The refractive error group AL and ACD were lower than those in the non-refractive error group(P＜0.05),and the lens thickness and average visual acuity were significantly higher than those in the non-refractive error group(P＜0.05).Multivariate logistic regression analysis showed that AL,ACD and lens thickness were factors affecting the occurrence of refractive error(P＜0.05).Conclusion Patients with glaucoma complicated with cataract can effectively improve visual acuity after combined surgery,but the proportion of refractive error is high,and AL,ACD and lens thickness are important factors affecting their occurrence.
