PIOL)。根据实际人眼的角膜地形图、眼内各组分的轴向间距和波前像差,运用ZEMAX光学设计软件,构建了个性化眼模型,然后运用该模型,设计了球柱PIOL和折射/衍射球柱PIOL。研究表明:与球柱PIOL相比,折射/衍射球柱PIOL能够全面提高人眼的白光调制传递函数 (Modulation Transfer Function
Refractive/diffractive spherocylindrical phakic intraocular lens (PIOL) is designed to improve the white light visual quality. The individual eye model is constructed with the measured individual corneal data
eyeball depth and wavefront aberrations with optical design software ZEMAX,then the spherocylindrical PIOL and the refractive/diffractive spherocylindrical PIOL are designed with the established eye model. It is shown in a comparison of spherocylindrical PIOL that the refractive/diffractive spherocylindrical PIOL can improve overall white light modulation transfer function (MTF) and the MTFs of non-center wavelengths
which can improve the visual quality. It is also shown that a zone of 4 millimeter is enough for the binary structure. At last
the fabrication issues are discussed. The refractive/diffractive spherocylindrical PIOL has potential application in advanced vision-correction.
