目的：观察区域折射人工晶状体SBL-3在年龄相关性白内障患者中的临床应用效果。

方法：选取2016-02/2017-12期间本院诊治的年龄相关性白内障患者90例90眼，随机分为对照组(45例45眼)和观察组(45例45眼)。对照组植入单焦点人工晶状体，观察组植入区域折射人工晶状体SBL-3。比较两组患者手术前后的裸眼视力、VF-14量表评分、角膜内皮细胞情况及术后对比敏感度。

结果：术前两组患者的裸眼视力、VF-14量表评分及角膜内皮细胞情况无明显差异(均P>0.05)。术后12wk，观察组患者的裸眼视力、VF-14量表评分优于对照组，明光及暗光对比敏感度低于对照组(均P<0.05)，而角膜内皮细胞情况、明光眩光及暗光眩光对比敏感度无明显差异(均P>0.05)。

结论：区域折射人工晶状体SBL-3在年龄相关性白内障患者中的临床应用效果较好，对患者的视觉质量有积极的改善作用，且对角膜的不良影响较小。

METHODS: Totally 90 patients(90 eyes)with age-related cataract diagnosed and treated in our hospital from February 2016 to December 2017 were selected as the study object, and they were randomly divided into control group and observation group, each group respectively included 45 cases(45 eyes). The control group were treated with single focus intraocular lens implantation, the observation group were treated with regional refraction intraocular lens SBL-3. Then the naked vision, VF-14 scale and corneal endothelial cells situation before and after the operation, contrast sensitivity after the operation of two groups were compared.

RESULTS: The naked vision, VF-14 scale and corneal endothelial cells of two groups before the operation were compared,the differences had no statistical significance(all P>0.05). After 12wk operation, the naked vision and VF-14 scale of observation group were better than those of control group, and contrast sensitivity of light and dark light were all lower than those of control group, the differences had statistical significance(all P<0.05), while the corneal endothelial cells, contrast sensitivity of light glare and dark glare of two groups were compared, the differences had no statistical significance(all P>0.05).

CONCLUSION: The clinical application effect of regional refraction intraocular lens SBL-3 in the patients with age-related cataract is better which has positive improvement effect for the visual quality, and the bad influence for the cornea is small, so its clinical application value is higher.
