To compare the optical performance and stability of different kinds of aspheric IOLs.
It was a retrospective case series study. Five different kinds of aspheric IOLs were implanted into 130 eyes after cataract operation, including hydrophilic acrylic IOLs (AO, Bausch&Lomb), 25 eyes; hydrophilic acrylic IOLs (20H, Rayner), 20 eyes; 3-piece hydrophilic acrylic IOLs (PY60AD, HOYA), 30 eyes; acrylic IOLs (ZC, B00, AMO), 25 eyes; and 3-piece hydrophobic acrylic IOLs (Tecnis 9003, ZA9003, 30 eyes). Straylight on the retina was measured with C-quant. IOLs tilt and decentration were measured using Scheimpflug system (Pentacam, Oculus) and image-analysis was performed by Image-pro plus 6.0 software. Difference among groups was evaluated by analysis of variance (ANOVA). The relationship between straylight parameters and age, best corrected visual acuity (BCVA), inner HOA and MTF (HOA, high order aberration; MTF, Modulation Transfer Function) at different spatial frequencies was evaluated by Pearson correlation analysis.
The mean C-quant measurements for AO, 920H, PY60AD, ZCB00 and ZA9003 groups were 1.33 ± 0.69, 1.43 ± 0.57, 1.56 ± 0.43, 1.61 ± 0.56 and 1.71 ± 0.72, respectively, which showed no statistically significant differences (F = 0.593;P = 0.669). The straylight values in AO and 920H groups were significantly lower than that of ZCB00 and ZA9003 groups (t = 2.159, 3.271 and 2.286; P = 0.045, 0.013, and 0.046). The mean IOL decentration and tilt measurements in the 5 different groups showed no statistically significant differences (F = 4.016, 3.985; P = 0.056, 0.064).
There are no significant difference in straylight between 5 different types of aspheric IOL implanted within the lens capsules. All of them show satisfy stability. One-piece design and hydrophilic material IOLs provide better optical performance than that of 3-piece 2-point haptic design.
比较不同类型非球面人工晶状体的光学性能和稳定性。
这是一项回顾性病例系列研究。白内障手术后，将五种不同类型的非球面人工晶状体植入130只眼中，包括亲水性丙烯酸人工晶状体（AO，博士伦），25只眼；亲水性丙烯酸人工晶状体（20H，雷纳），20只眼；三件式亲水性丙烯酸人工晶状体（PY60AD，豪雅），30只眼；丙烯酸人工晶状体（ZC，B00，爱尔康），25只眼；以及三件式疏水性丙烯酸人工晶状体（Tecnis 9003，ZA9003，30只眼）。使用C-Quant测量视网膜上的散射光。使用Scheimpflug系统（Pentacam，奥culus）测量人工晶状体的倾斜和偏心，并通过Image-pro plus 6.0软件进行图像分析。通过方差分析（ANOVA）评估组间差异。通过Pearson相关分析评估不同空间频率下散射光参数与年龄、最佳矫正视力（BCVA）、内部高阶像差（HOA）和调制传递函数（MTF）（HOA，高阶像差；MTF，调制传递函数）之间的关系。
AO、920H、PY60AD、ZCB00和ZA9003组的平均C-Quant测量值分别为1.33±0.69、1.43±0.57、1.56±0.43、1.61±0.56和1.71±0.72，差异无统计学意义（F = 0.593；P = 0.669）。AO组和920H组的散射光值显著低于ZCB00组和ZA9003组（t = 2.159、3.271和2.286；P = 0.045、0.013和0.046）。5个不同组的人工晶状体偏心和倾斜测量平均值差异无统计学意义（F = 4.016、3.985；P = 0.056、0.064）。
植入晶状体囊袋内的5种不同类型非球面人工晶状体的散射光无显著差异。它们均表现出良好的稳定性。一体式设计和亲水性材料的人工晶状体比三件式两点式袢设计提供更好的光学性能。
