A new, to the best of our knowledge, optical element designed to compensate regular astigmatism while exhibiting increased tolerance to rotational misalignment is introduced. The element incorporates an optical design based on concentric annular regions with slightly different cylindrical axis angular positions. To assess visual quality performance as a function of rotation, retinal image simulation and clinical assessments with an adaptive optics visual simulator were carried out. The results demonstrate the superior performance of the newly proposed element in the presence of rotational errors when compared to traditional solutions.

多复曲面光学元件可补偿眼部散光，并增加旋转时的耐受性

据我们所知，推出了一种新的光学元件，旨在补偿常规散光，同时表现出对旋转未对准的更大容忍度。该元件采用了基于同心环形区域的光学设计，其柱轴角位置略有不同。为了评估作为旋转函数的视觉质量性能，使用自适应光学视觉模拟器进行了视网膜图像模拟和临床评估。结果表明，与传统解决方案相比，新提出的元件在存在旋转误差的情况下具有优越的性能。
