Abstract： AIM:To observe the efficacy of phacoemulsification combined with capsular tension ring and intraocular lens implantation in the treatment of high myopia with cataract.METHODS:Retrospective study.A total of 82 cases(82 eyes)of high myopia complicated with cataract who admitted to the cataract department of our hospital from December 2021 to April 2023 were selected as study objects,and they were divided into control group(n=39)and combination group(n=43)according to whether or not the capsular tension ring was used intraoperatively.Patients in the control group were treated with intraocular lens implantation alone,and those in the combination group were treated with phacoemulsification combined with capsular tension ring and intraocular lens implantation.The preoperative and postoperative best corrected visual acuity,central anterior chamber depth,trabecular ciliary process,visual quality and complications were compared.RESULTS:At 1 mo after surgery,the best corrected visual acuity(LogMAR)of both groups increased significantly(combination group:0.64±0.28 vs0.12±0.14;control group:0.62±0.26 vs 0.23±0.25,both P＜0.001).Central anterior chamber depth in both groups were higher than those before surgery(combination group:2.57±0.56 vs1.97±0.40 mm;control group:2.22±0.45 vs 1.89±0.37 mm;both P＜0.001),and the best corrected visual acuity and central anterior chamber depth of the combination group were significantly better than those of the control group(both P＜0.05).The distance of trabecular ciliary process showed no statistical significance(combination group:0.68±0.22 vs 0.74± 0.20 mm;control group:0.74±0.19 vs0.78±0.17 mm,both P＞0.05).The visual quality scores of the combination group were all higher than the control group at 1 mo after surgery[watching TV:3.00±0.38 vs 2.22±0.46 points;reading books:2.85±0.42 vs 2.21±0.44 points;night vision:2.71±0.34 vs2.37±0.41 points;fine operation:2.82±0.38 vs 2.33±0.40 points,all P＜0.001].The incidence of complication in the combination group was significantly lower than that of the control group(33％vs 14％,P＜0.05).CONCLUSION:Phacoemulsification combined with capsular tension ring and intraocular lens implantation can effectively promote the recovery of visual function,improve the structure of chamber angle,and reduce the incidence of complications in the treatment of patients with high myopia and cataract.
