目的：探讨区域折射多焦点人工晶状体SBL-3的临床应用效果。

方法：选取2016-02/2017-06于本院行白内障超声乳化摘除术联合多焦点人工晶状体SBL-3植入的26例26眼年龄相关性白内障患者纳入SBL-3组； 选取同期于本院行白内障超声乳化摘除术联合单焦点人工晶状体TecnisZA9003植入的28例28眼年龄相关性白内障患者纳入对照组。比较两组患者术后3mo的裸眼视力、矫正视力、对比敏感度及患者满意度。

结果：术前两组患者的裸眼远、中、近视力相比差异均无统计学意义(P>0.05)。术后3mo，两组患者的裸眼远、中、近视力较术前均得到明显改善(P<0.05)； SBL-3组患者裸眼中近视力、最佳矫正远视力下中视力和近视力均显著优于对照组(P<0.05)； SBL-3组患者在明光、暗光、明光眩光和暗光眩光下不同空间频率(3、6、12、18c/d)的对比敏感度以及视觉质量满意度均显著优于对照组(P<0.05)。

结论：区域折射多焦点人工晶状体SBL-3不仅可以提供较好的远视力，还可提供更佳的中视力、近视力以及对比敏感度，极大地提高了患者术后的视觉质量满意度。

METHODS:Totally 26 cases(26 eyes)of age-related cataract who received phacoemulsification and implantation of MIOL SBL-3 were enrolled from February 2016 to June 2017 in our hospital as the SBL-3 group. And 28 cases(28 eyes)of age-related cataract who received phacoemulsification and implantation of single focus intraocular lens intraocular lens TecnisZA9003 were enrolled as control group. At postoperative 3mo, the uncorrected visual acuity, corrected visual acuity, contrast sensitivity and patient satisfaction were compared between two groups.

RESULTS: At preoperative, there was no statistical difference in uncorrected distance, intermediate and near visual acuity between two groups(P>0.05). At postoperatively 3mo, the uncorrected distance, intermediate and near visual acuity in patients of both groups were significantly improved(P<0.05). At postoperative 3mo, the uncorrected intermediate and near visual acuity, distance-corrected intermediate and near visual acuity, contrast sensitivity at different spatial frequencies(3, 6, 12, 18c/d)and patient satisfaction in SBL-3 group were significantly better than those of control group(P<0.05).

CONCLUSION: The MIOL SBL-3 not only could provide preferable distance visual acuity, but also could provide better intermediate visual acuity, near visual acuity and contrast sensitivity, and greatly increase the visual quality and satisfaction at postoperative in cataract patients.
