含泪膜的人眼模型的建立及其光学特性研究

A New Model of Human Eye Considering Tear Film and the Optical Characters

在Hwey Lan Liou眼模型的基础上,提出在角膜前表面加入泪膜,建立了新的解剖学准确的眼光学模型。与以往只有4个或者更少折射面的眼模型不同,由于考虑泪膜,这一眼模型有5 个折射面。新建眼模型的轴长为23.93 mm,在543 nm波长下,屈光度为60.4 D。分析了新建眼模型的球差和光学传递函数(MTF),由新建的眼模型计算出的球差及零视场下的MTF与实验值符合得较好。

A new anatomically accurate eye model with tear film in front of the cornea was proposed based on the eye model proposed by Hwey-Lan Liou.Due to incorporating tear film into the eye model,the model has five refractive surfaces,thus distinguishing it from previously published eye models that have four or fewer refractive surfaces.It has an equivalent power of 60.40 D,and an axial length of 23.93 mm,The eye model results in spherical aberration in good agreement with experimental data.
