提出一种在个体眼光学结构基础上根据波前数据设计波前眼镜的新方法。建立了个性化的眼光学结构,并将眼球和镜片视为统一的镜一眼光学系统,用光学设计的优化方法给出镜片的结构数据,并分析了±7°视场和眼球旋转±20°时,该镜一眼系统的成像情况。与波前拟合的方法相比,该方法设计的波前眼镜离焦差为(-0.057±0.015)m^-1,像散差为(0.015±0.013)m^-1散光轴位差为(0.100±0.316)°。镜一眼系统的矫正视力均大于1.25,其中8只被试眼的视力可达1.5以上。10只被试眼在转动±20°情形下的0°视场成像相比于直视的情况均略有下降,而7°视场的成像质量相比于直视的情况下降则更为明显。由该方法给出的验光结果客观可信,可用于对佩戴波前眼镜后人眼的视觉质量的预先评估。

A new method to design a wavefront-guided lens is proposed based on an individual eye optical model. The individual eye model is constructed, then by regarding the eyeball and the wavefront-guided lens as a single system. For the lens-eye system, the surface profiles of the lens are determined by optimizing the lens design. In addition, the visual performance of the lens-eye system is analyzed for both _+ 7 ~ field of view and ± 20° rotation of the eyeball. In comparison with the results from wavefront fitting, the prescription difference in defocus, astigmatism and in the axis of astigmatism are ( -0. 057 ±0. 015 ) m^-1, (0. 015±0. 013 ) ^-1 (0. 100±0. 316)°, respectively. Furthermore the visual acuity of the lens-eye system is above 1 25 because of the correction of the wavefront-guided lens. The visual acuity for the eight eyes is as high as 1.5. For a field of view of 0°, the performance for the eye without rotation is better than that of eyes with a rotation of 20°. However, for a field of view of 7°, the performance for eyes without rotation is much better than thatof eyes with new method front-guided a rotation of ± 20°. Experiments show that the prescription of the wavefront-guided lens from the is objective and reliable and it is possible to predict the visual quality of the eye with the wave-front-guided lens.
