The two-dimensional complex OTF can be computed from a particular set of wave front aberrations obtained for a given wavelength and pupil diameter. Here we employ established techniques to extend this calculation to other pupil diameters and to white light. We apply these techniques to a set of 200 eyes for which aberration data were collected by Thibos et al. (2002). We compute the MTF, its radial average, and then the population radial average. We then approximate the population radial average with a mathematical formula. The data we used in this study consisted of wave front aberrations for 200 eyes from 100 individuals with normal healthy vision (Thibos et al., 2002). The average age of the subjects was 26.1 years. Wave fronts were measured at a wavelength of 633 nm and referenced to a 6 mm pupil. Subjectively measured sphero-cylindrical refractive errors were corrected before the wave front measurement, but subsequent measurements included residual lower order aberrations that we included in our calculations. Each set of aberrations was expressed as Zernike coefficients for the first 35 modes. To compute the mean radial MTF for each pupil diameter, we performed the following steps.
