To compare the visual outcome findings between a new monofocal intraocular lens (IOL) (Tecnis Eyhance) and extended depth of focus (EDOF) IOL (Appasamy Supraphob Infocus).
This prospective comparative interventional study evaluated 31 patients after implantation of Tecnis Eyhance (15 patients) and Supraphob EDOF IOL (16 patients). The uncorrected and corrected distance and intermediate and near visual acuity were measured at postoperative day 1, 1 week, 4 week, and 3 months. Contrast sensitivity, incidence of halos and glares, and patient satisfaction were assessed at 3 months postoperatively.
The Tecnis Eyhance ( = 15) and Supraphob EDOF ( = 16) group were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The average age distribution of participants was 56 ± 6 years. Postoperatively, both groups had similar distance and intermediate vision, but the near vision was significantly better in the EDOF group ( < 0.01) as compared to Tecnis Eyhance at 3 months. The contrast sensitivity and patient satisfaction were similar in both the groups. The incidence of halos and glares was present in the EDOF group, but it was statistically insignificant.
The Tecnis Eyhance and Supraphob EDOF both were effective in improving distance and intermediate vision, but the near vision was significantly better in the EDOF group. Both the groups retained good contrast sensitivity and the majority of patients were satisfied.
比较新型单焦点人工晶状体（IOL）（Tecnis Eyhance）与扩展景深（EDOF）人工晶状体（Appasamy Supraphob Infocus）的视觉结果。
这项前瞻性比较干预性研究评估了31例分别植入Tecnis Eyhance（15例患者）和Supraphob EDOF人工晶状体（16例患者）的患者。在术后第1天、1周、4周和3个月测量未矫正和矫正的远、中、近视力。在术后3个月评估对比敏感度、光晕和眩光的发生率以及患者满意度。
Tecnis Eyhance组（n = 15）和Supraphob EDOF组（n = 16）在所有术前参数（包括生物测量、视力和白内障状态）方面具有可比性。参与者的平均年龄分布为56±6岁。术后，两组的远视力和中视力相似，但在3个月时，EDOF组的近视力明显优于Tecnis Eyhance组（P<0.01）。两组的对比敏感度和患者满意度相似。EDOF组出现了光晕和眩光，但在统计学上无显著意义。
Tecnis Eyhance和Supraphob EDOF在改善远视力和中视力方面均有效，但EDOF组的近视力明显更好。两组均保持了良好的对比敏感度，大多数患者感到满意。
