衍射型多焦点人工晶状体对年龄相关性白内障患者视力恢复的影响

Effect of Diffracted Multifocus Intraocular Lens on Visual Recovery in Patients with Age-Related Cataract

目的探讨衍射型多焦点人工晶状体对年龄相关性白内障患者视力恢复的影响。方法选取焦作市五官医院自2018年12月至2020年6月收治的120例年龄相关性白内障患者,按照治疗方法不同将其分为研究组(60例)与对照组(60例)。患者均行白内障超声乳化吸出+人工晶状体植入术(研究组植入衍射型多焦点人工晶状体,对照组植入单焦点人工晶状体),观察两组在视力恢复、视质量等方面的差异。结果手术前研究组、对照组裸眼远、近视力(UCDVA、UCNVA)、最佳矫正远、近视力(BCDVA、BCNVA)比较,差异无统计学意义(P>0.05),术后6个月,研究组各指标显著大于对照组,差异有统计学意义(P<0.05)。术前、术后两组中央角膜厚度(CCT)、角膜内皮细胞密度(ECD)及六角形细胞比例比较,差异无统计学意义(P>0.05)。术前两组视质量(VF-QOL)评分比较,差异无统计学意义(P>0.05),术后6个月,研究组VF评分、QOL评分显著高于对照组,差异有统计学意义(P<0.05)。两组患者近距离阅读时老视镜依赖性对比,研究组和对照组脱镜率分别为73.33%和55.00%,其中研究组脱镜率更高,差异有统计学意义(P<0.05)。两组患者视觉满意度比较,研究组和对照组的视觉满意度分别为95.00%和83.33%,比较之下研究组更高,差异有统计学意义(P<0.05)。结论年龄相关性白内障患者在选择置入人工晶体时,可优先选择多焦点人工晶状体,不仅有助于远期视力、视功能的恢复,同时有助于提高患者生活质量。

Objective To investigate the effect of diffracted multi-focus intraocular lens(IOL)on visual acuity recovery in age-related cataract patients.Methods A total of 120 cases of age-related cataract patients treated in Jiaozuo ophthalmology and otorhinolaryngology Hospital from December 2018 to June 2020 were selected as subjects,according to the treatment method,they were divided into research group(60 cases)and control group(60 cases),patients were treated by cataract ultrasonic emulsification suck out combined with intraocular lens implantation(the study group was implanted with diffracted multi-focus IOL,the control group was implanted with single-focus IOL),and the differences in visual acuity recovery and visual quality were observed between the two groups.Results Before operation,there were no significant differences in far and near visual acuity(UCDVA,UCNVA),best corrected far and near visual acuity(BCDVA,BCNVA)between the study group and the control group(P>0.05).Six months after operation,the indexes in the study group were significantly higher than those in the control group(P<0.05).There were no significant differences in central corneal thickness(CCT),corneal endothelial cell density(ECD)and proportion of hexagonal cells between the two groups before and after operation(P>0.05).There was no significant difference in visual quality(VF-QOL)score between the two groups before surgery(P>0.05),the VF score and QOL score in the study group were significantly higher than those in the control group 6 months after surgery(P<0.05).Comparison of presbyopia dependence between the two groups of patients in close reading showed that the rate of deoscopy in the study group and the control group was 73.3%and 55.00%respectively,and the rate of deoscopy in the study group was higher(P<0.05).Comparison of visual satisfaction between the two groups showed that the visual satisfaction of the study group and the control group was 95.00%and 83.33%,respectively,and the visual satisfaction of the study group was higher(P<0.05).Conclusion Multifocus IOL should be preferred for age-related cataract patients,which not only contributes to the recovery of long-term vision and visual function,but also improves the quality of life of patients.
