To evaluate the effect of asphericity and blue light filter (BLF) of three different intraocular lenses (IOLs) on the visual performance, second- and third-order aberrations (defocus, coma, trefoil), and contrast sensitivity after uneventful cataract surgery.
One hundred and twenty eyes of 60 patients with clinically significant cataract were randomly assigned to receive one of the three IOL types: Bioline Yellow Accurate (aspheric, with BLF, i-medical, Germany), BioAcryl 60125 (spherical, without BLF, Biotech, France), and H65C/N (aspheric, without BLF, PhysIOL, Belgium). Each IOL was implanted in 40 eyes. Complete ophthalmologic examination, functional acuity contrast testing and wavefront analysis were performed 60 days postoperatively.
The mean postoperative best-corrected visual acuity (BCVA) was 0.95 0.08, not differing statistically among the IOL groups ( = 0.83). Mean defocus and coma values did not yield any statistically significant difference through the IOL groups varying from -0.784 to -0.614 μm and 0.129 to 0.198 μm ( = 0.79 and 0.34, respectively). Bioline Yellow Accurate IOL presented less trefoil aberrations, 0.108 0.05 μm, compared to the other two IOL types (BioAcryl [0.206 0.19 μm] and Physiol [0.193 0.17 μm], 0.05). Contrast sensitivity values did not differ among the groups under all lighting conditions. Bioline Yellow IOL showed a statistically higher loss of contrast sensitivity (between mesopic and mesopic with glare conditions) compared to the BioAcryl and PhysIOL in 12 and 3 cpd spatial frequencies, respectively ( 0.05).
Bioline Yellow IOL indicated lower contrast sensitivity under mesopic conditions when glare was applied but resulted in less trefoil aberrations after uneventful cataract surgery. No further differences were noted in postoperative visual performance among three IOL groups.
评估三种不同人工晶状体（IOL）的非球面性和蓝光滤过（BLF）对白内障手术顺利完成后的视觉性能、二阶和三阶像差（散焦、彗差、三叶草像差）以及对比敏感度的影响。
60例患有临床显著性白内障的患者的120只眼睛被随机分配接受三种IOL类型之一：Bioline Yellow Accurate（非球面，带BLF，i - medical，德国）、BioAcryl 60125（球面，不带BLF，Biotech，法国）和H65C/N（非球面，不带BLF，PhysIOL，比利时）。每种IOL植入40只眼睛。术后60天进行完整的眼科检查、功能性视力对比测试和波前分析。
术后平均最佳矫正视力（BCVA）为0.95±0.08，IOL组之间无统计学差异（P = 0.83）。平均散焦和彗差值在IOL组之间无任何统计学显著差异，范围从 - 0.784至 - 0.614μm和0.129至0.198μm（P分别为0.79和0.34）。与其他两种IOL类型（BioAcryl [0.206±0.19μm]和Physiol [0.193±0.17μm]）相比，Bioline Yellow Accurate IOL的三叶草像差更少，为0.108±0.05μm（P < 0.05）。在所有光照条件下，各组之间的对比敏感度值无差异。与BioAcryl和PhysIOL相比，Bioline Yellow IOL在12和3 cpd空间频率下分别显示出在中暗视觉和有眩光的中暗视觉条件下对比敏感度的统计学显著更高损失（P < 0.05）。
Bioline Yellow IOL在有眩光的中暗视觉条件下显示出较低的对比敏感度，但在白内障手术顺利完成后导致较少的三叶草像差。三个IOL组之间在术后视觉性能方面未发现进一步差异。
