To report the outcomes of macular add-on intraocular lens implantation in improving reading vision in patients with bilateral advanced diabetic maculopathy.
In this retrospective study, a supplementary bifocal sulcus intraocular lens (Scharioth Macular Lens) was implanted in the better-seeing eye of five patients. Baseline-corrected distance vision, corrected near visual acuity, a preoperative simulation test, and multimodal imaging were collected. The primary outcome was the uncorrected near visual acuity at a working distance of 15 cm, at a 12-month follow-up.
Study patients included 3 cases of refractory subfoveal exudation and 2 cases of diabetic macular ischemia. A preoperative test to assess the potential gain in near vision showed an improvement of ≥2 paragraphs on the RADNER reading chart in all patients. At 12 months, median reading vision (corrected near visual acuity at 15 cm) significantly improved from 20/125 (range 20/50-20/200) preoperatively to uncorrected near visual acuity (at 15 cm) of 20/50 (range 20/40-20/80) (P = 0.042; Wilcoxon signed-ranks test). Distance vision remained unchanged in four patients. All patients were able to achieve the size of newsprint (20/50 Snellen equivalent), within the first 3 months.
The macular add-on intraocular lens improves reading vision in visually impaired patients due to end-stage diabetic macular disease.
报告黄斑附加型人工晶状体植入术改善双侧晚期糖尿病性黄斑病变患者阅读视力的效果。
在这项回顾性研究中，为5例患者视力较好的眼植入了一种补充性双焦点沟内人工晶状体（Scharioth黄斑晶状体）。收集了基线校正后的远视力、校正后的近视力、术前模拟测试和多模态成像资料。主要结局指标是随访12个月时在15 cm工作距离下的未矫正近视力。
研究患者包括3例难治性黄斑下渗出和2例糖尿病性黄斑缺血。术前评估近视力潜在改善情况的测试显示，所有患者在RADNER阅读图表上的改善≥2行。12个月时，中位阅读视力（15 cm处的校正近视力）从术前的20/125（范围20/50 - 20/200）显著提高到未矫正近视力（15 cm处）的20/50（范围20/40 - 20/80）（P = 0.042；Wilcoxon符号秩检验）。4例患者的远视力保持不变。所有患者在最初3个月内都能达到报纸印刷字体大小（相当于20/50 Snellen视力）。
黄斑附加型人工晶状体可改善终末期糖尿病性黄斑病变所致视力障碍患者的阅读视力。
