AIM:To observe the clinical application effect of regional refraction intraocular lens SBL-3 in patients with age-related cataract.

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.
