    • A method of determining an ophthalmic prescription (Rx) for a patient's eye, includes obtaining a wavefront measurement of the patient's eye; determining a first Rx for the patient's eye from the wavefront measurement, the first Rx corresponding to a maximum value of a merit function calculated from the wavefront measurement of the patient's eye for a first size of the pupil of the patient's eye; determining one or more additional Rx's of the patient's eye for one or more additional pupil sizes different from the first pupil size, wherein each additional Rx is determined for a corresponding size by calculating a value of the merit function for the previously-calculated Rx at the corresponding size and searching for an Rx at the corresponding size that provides a larger value of the merit function than the previously-calculated Rx at the corresponding size; determining a final Rx based on the first Rx and the additional Rx's; and outputting the final Rx.
    • 确定患者眼睛的眼科处方(Rx)的方法包括:获得患者眼睛的波前测量; 从波前测量确定患者眼睛的第一Rx,第一Rx对应于从患者眼睛的第一大小的患者眼睛的波前测量计算的优值函数的最大值; 确定与第一瞳孔大小不同的一个或多个附加瞳孔尺寸的患者眼睛的一个或多个附加的Rx,其中通过计算先前计算的Rx的优值函数的值来确定每个附加的Rx对应的大小 以相应的大小搜索相对应的尺寸的Rx,其提供比先前计算的相应尺寸的Rx更好的优值函数值; 基于第一Rx和附加Rx确定最终的Rx; 并输出最终的Rx。
