Abstract
We compared measured wave aberrations in pseudophakic eyes implanted with aspheric intraocular lenses (IOLs) with simulated aberrations from numerical ray tracing on customized computer eye models, built using quantitative 3-D OCT-based patient-specific ocular geometry. Experimental and simulated aberrations show high correlation (R = 0.93; p<0.0001) and similarity (RMS for high order aberrations discrepancies within 23.58%). This study shows that full OCT-based pseudophakic custom computer eye models allow understanding the relative contribution of optical geometrical and surgically-related factors to image quality, and are an excellent tool for characterizing and improving cataract surgery.
摘要
我们将植入非球面人工晶状体（IOL）的假晶状体眼的实测波像差与基于定量三维光学相干断层扫描（OCT）的患者特定眼部几何结构构建的定制计算机眼模型上的数值光线追踪模拟像差进行了比较。实验像差和模拟像差显示出高度相关性（R = 0.93；p<0.0001）和相似性（高阶像差差异的均方根在23.58%以内）。这项研究表明，基于完整OCT的假晶状体定制计算机眼模型有助于理解光学几何因素和手术相关因素对图像质量的相对贡献，并且是表征和改进白内障手术的极佳工具。
