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.
