Work remains to be done to understand the origins of ocular aberrations. We analyze lens aberrations of several species with Y-suture branches (bovine, ovine, and porcine) and their relationship with suture distribution. Aberrations are measured in vitro with a point diffraction interferometer in 10 different eyes of each species. The minimum number of Zernike polynomials minimizing the root mean square error of the wavefront is estimated by processing the interferograms. Through this we find significant amounts of astigmatism, coma, spherical aberration, and trefoil in the lenses of the three species. Moreover, we observe a high degree of correlation between the orientation of the lens sutures and the axis of nonrotationally symmetric aberrations. Our results point to lens sutures as the histological origin of the most significant lens aberrations: astigmatism, coma, and trefoil, but we are unable to find a major suture governing all the axes.
仍需进一步研究以了解眼像差的起源。我们分析了几种带有 Y 缝线分支的物种（牛、羊和猪）的晶状体像差及其与缝线分布的关系。在每种动物的 10 只眼中，我们使用点衍射干涉仪在体外测量像差。通过处理干涉图，估计出最小均方根误差的泽尼克多项式的最小数量。通过这种方法，我们发现这三种动物的晶状体中存在大量的散光、彗差、球差和三叶差。此外，我们观察到晶状体缝线的方向与非旋转对称像差的轴之间存在高度相关性。我们的研究结果表明，晶状体缝线是晶状体中最重要的像差（散光、彗差和三叶差）的组织学起源，但我们无法找到一个主要的缝线来控制所有的轴。
