基于波前像差的个性化人工晶体设计

在个性化人眼光学结构的基础上，运用ZEMAX软件的优化功能，设计了符合实际人眼光学特性的个性化人工晶体。该人工晶体不仅可以矫正离焦和像散，还引入了非球面可以矫正人眼的球差。文中将个性化人工晶体优化后得到的屈光度与经验公式计算得到的屈光度作了比较，在经验公式0.25D精确度的基础上有了提高，并直观地描述了个性化人工晶体植入前后人眼调制度和分辨率的变化情况。对样本人眼矫正后人眼分辨率最大变化由28 L/mm提高到118 L/mm，调制度由0.02提高至0.51。分析结果表明，个性化植入人工晶体的方法可以提高人眼矫正的精确度，不同人眼的波前特性不同，矫正效果也有相应的差异。

Design of individual intraocular lens based on wavefront aberrations

In this article, the individual intraocular lens in accordance with human visual characterists has been designed based on individual eye structure with optical design software ZEMAX , which can correct not only the defocus and astigmatism , but also the spherical aberrations by aspheric surface design .The power calculated from the individual intraocular lens is compered with that caculated from the experiential formula , showing an improvement of precision higher than 0.25D.The variation of the modulation and the resolution of human eye has been shown visually before and after the implantation of intraocular lens .The resolution has been improved from 28 L/mm to 118 L/mm, while the modulation has been improved from 0.02 to 0.51.The results show that the individual intraocular lens design has more accuracy , and the difference exists in correct effect because of the different optical properties of human eyes .
