Ametropic Eye Modeling

Using a commercial optical design software, a general ametropic eye model was constructed based on the measured data of 69 young adults. The experiment data was obtained from 2 published literatures. The correlation between refractive errors of the eyes and their axial lengths, cornea curvatures and intraocular powers was investigated and adopted into the modeling for the first time. The optical performance of the new model eye was evaluated and compared with published aberration data from human eyes. The comparison was performed on both on-axis and periphery vision. High-order wavefront aberrations that include the asymmetric properties of eyes and the correlation of high-order aberrations with refractive error were also discussed.
