The aim was to study the visual performance of a new refractive extended depth of focus (EDOF) intraocular lens (IOL).
Prospective, comparative study.
Consenting patients with age-related cataract willing for bilateral cataract surgery within 2 weeks were implanted with the Supraphob EDOF IOL and those willing for 1 eye surgery were implanted with a monofocal IOL. The uncorrected and best-corrected distance, intermediate and near visual acuity, and contrast sensitivity were evaluated at 1 and 3 months postoperatively. We also inquired about glare, halos, difficulties in night driving, requirement for spectacles, and overall satisfaction with vision.
The Supraphob EDOF group (n = 72 eyes) and the monofocal IOL group (n = 54 eyes) were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The mean age of participants was 58.4 ± 10.6 years. Both groups had similar distance vision but the EDOF group had significantly better intermediate (0.2 ± 0.2 logMAR vs 0.75 ± 0.19 logMAR, P < 0.001) and near vision (median = N6 vs N12, P < 0.001) compared to the monofocal group at 3 months. The contrast sensitivity was similar in both groups. Patients in the EDOF IOL group had much greater satisfaction for intermediate and near vision. Less than 10% patients reported glare, halos, and difficulty in driving at night in the EDOF group.
The Supraphob EDOF IOL was effective in improving the distance, intermediate and near vision in majority of patients, and retained good contrast sensitivity with most patients reporting excellent satisfaction.
研究一种新的折射性扩展景深(EDOF)人工晶状体(IOL)的视觉性能。
前瞻性、对照研究。
同意接受双眼白内障手术且在 2 周内接受双侧白内障手术的患者植入 Supraphob EDOF IOL,而愿意接受单眼手术的患者植入单焦点 IOL。术后 1 个月和 3 个月评估未矫正和最佳矫正的远、中、近视力以及对比敏感度。我们还询问了眩光、晕影、夜间驾驶困难、对眼镜的需求以及对整体视力的满意度。
Supraphob EDOF 组(n=72 只眼)和单焦点 IOL 组(n=54 只眼)在所有术前参数方面(包括生物测量、视力和白内障状况)均具有可比性。参与者的平均年龄为 58.4±10.6 岁。两组的远视力相似,但 EDOF 组的中距离视力(0.2±0.2 logMAR 与 0.75±0.19 logMAR,P<0.001)和近视力(中位数= N6 与 N12,P<0.001)明显优于单焦点组。两组的对比敏感度相似。EDOF IOL 组的患者对中距离和近视力的满意度更高。EDOF 组中不到 10%的患者报告有眩光、晕影和夜间驾驶困难。
Supraphob EDOF IOL 能有效改善大多数患者的远、中、近视力,保持良好的对比敏感度,大多数患者报告满意度极高。
