超声乳化白内障摘出联合囊袋张力环植入术治疗高度近视伴白内障的效果及对人工晶体稳定性、视力状态的影响

Effect of phacoemulsification cataract extraction combined with capsular tension ring implantation in the treatment of high myopia with cataract and its influences on intraocular lens stability and visual acuity

目的分析超声乳化白内障摘出联合囊袋张力环植入术治疗高度近视伴白内障的效果。方法选择2019年2月至2022年3月收治的90例高度近视伴白内障患者为研究对象,以随机数字表法将其分为对照组和观察组,各45例。对照组接受超声乳化白内障摘出治疗,观察组在对照组基础上加施囊袋张力环植入术治疗。比较两组的治疗效果。结果术后6个月,观察组的最佳矫正视力(BCVA)、角膜内皮细胞密度、六边形细胞百分率高于对照组,中央角膜厚度小于对照组(P<0.05)。术后3、6个月,观察组的晶体偏心量、倾斜角小于对照组(P<0.05)。术后6个月,观察组的三叶草像差、总高阶像差、球差、彗差优于对照组(P<0.05)。观察组的术后并发症总发生率低于对照组(P<0.05)。结论超声乳化白内障摘出联合囊袋张力环植入术治疗高度近视伴白内障可提高人工晶体稳定性,改善角膜质量,还能降低术后并发症发生风险,促进视力恢复,值得推广。

Objective To analyze the effect of phacoemulsification cataract extraction combined with capsular tension ring implantation in the treatment of high myopia with cataract.Methods A total of 90 patients with high myopia and cataract admitted from February 2019 to March 2022 were selected as the research objects and divided into control group and observation group by random number table method,with 45 cases in each group.The control group was treated with phacoemulsification cataract extraction,and the observation group was treated with capsular tension ring implantation on the basis of the control group.The therapeutic effects of the two groups were compared.Results At 6 months after operation,the best corrected visual acuity(BCVA),corneal endothelial cell density and hexagonal cell percentage of the observation group were higher than those of the control group,and the central corneal thickness was smaller than that of the control group(P<0.05).At 3 and 6 months after operation,the crystal eccentricity and tilt angle of the observation group were smaller than those of the control group(P<0.05).At 6 months after operation,the trefoil aberration,total higher-order aberration,spherical aberration and coma aberration in the observation group were better than those in the control group(P<0.05).The total incidence of postoperative complications in the observation group was lower than that in the control group(P<0.05).Conclusion Phacoemulsification cataract extraction combined with capsular tension ring implantation in the treatment of high myopia with cataract can improve the stability of intraocular lens,improve corneal quality,reduce the risk of postoperative complications and promote visual acuity recovery,which is worthy of promotion.
