Akreos AO and Kontur AB are two commonly used intraocular lenses (IOLs) in Iran. This study was designed to evaluate the visual performance of these lenses.
In a comparative interventional study, 35 patients (70 eyes) were recruited, and each IOL was implanted in one eye of the patients, randomly. Best corrected visual acuity (BCVA), contrast sensitivity, aberrometric analysis, and depth of focus were evaluated 1 month and 3 months postoperatively. A visual quality questionnaire was also filled for each eye, and the results were compared.
Mean age of the patients was 60.97 ± 7.00 years. BCVA was not significantly different between the two eyes, before, 1 month, and 3 months postoperatively (p > 0.05 for all). Photopic and mesopic contrast sensitivity was not different between the two lenses instead of photopic 18 cycles per degree, 3 months postoperatively and in mesopic 6 cycles per degree 1 month postoperatively (p = 0.034 and p = 0.002, respectively). Aberrometric factors including HoRMS, Total RMS, and Higher order without Z(4,0) were not significantly different between the two lenses (p > 0.05 for all), but they were slightly lower for Akreos AO. Post-operative distance-corrected visual acuity for intermediate and near vision were not different between the two groups (p > 0.05, respectively).
Visual performance of Akreos AO and Kontur AB is similar. However, contrast sensitivity and aberrometric parameters are slightly better for Akreos AO IOL.
Akreos AO和Kontur AB是伊朗常用的两种人工晶状体（IOL）。本研究旨在评估这些晶状体的视觉性能。
在一项对比干预性研究中，招募了35例患者（70只眼），每个晶状体随机植入患者的一只眼中。在术后1个月和3个月评估最佳矫正视力（BCVA）、对比敏感度、像差分析和焦深。还为每只眼填写了一份视觉质量问卷，并对结果进行比较。
患者的平均年龄为60.97±7.00岁。术前、术后1个月和3个月，两眼之间的BCVA无显著差异（所有p>0.05）。在术后3个月每度18周的明视觉和术后1个月每度6周的中视觉中，两种晶状体之间的明视觉和中视觉对比敏感度没有差异（分别为p = 0.034和p = 0.002）。包括水平均方根（HoRMS）、总均方根（Total RMS）和不包括Z(4,0)的高阶像差在内的像差因素在两种晶状体之间无显著差异（所有p>0.05），但Akreos AO的这些因素略低。两组之间中间和近视力的术后距离矫正视力无差异（分别为p>0.05）。
Akreos AO和Kontur AB的视觉性能相似。然而，Akreos AO人工晶状体的对比敏感度和像差参数略好。
