为探究二次曲面前房型有晶体眼人工晶体的球差矫正特性，进行了球面和二次曲面有晶体眼人工晶体的设计，并利用像差理论对二者的球差矫正特性进行了研究.基于R.Navarro等人提出的模型眼得到屈光不正眼模型，利用ZEMAX光学软件分别设计了可矫正屈光不正人眼的球面与二次曲面前房型有晶体眼人工晶体.通过对光学传递函数和Zernike球差系数的比较，以及对Seidel球差分布系数的计算分析发现:在保证屈光不正矫正至正常水平的前提下，较之传统球面人工晶体，二次曲面的引入仅对远视眼的球差有矫正作用，并使光学传递函数显著改善；而对近视眼而言，二次曲面人工晶体的球差矫正效果与球面人工晶体相当.这一结论对前房型有晶体眼人工晶体的设计和应用具有重要的理论指导意义.

In order to explore the property of the conical anterior chamber phakic intraocular lenses (PIOL) in the spherical aberration correction, spherical and conical surface PIOLs were designed, and the characters of spherical aberration correction were researched. Based on the model eye of R. Navarro et al, the spherical and conical surface anterior chamber phakic intraocular lenses for the ametropia correction were designed with ZEMAX software. After the comparison of modulate transform function (MTF) and Zernike spherical aberration, and the analysis of Seidel spherical aberration, it was found that compared with a spherical surface, on the premise of the ocular refractive error being corrected, the conical surface can correct the spherical aberration and make MTF improved observably for hyperopia more than myopia. The correction of spherical aberration for myopia with spherical and conical PIOLs is equivalent. This conclusion would be useful for the design and application of anterior chamber PIOLs.
