AbstractWavefront aberrations were measured using a psychophysical ray-tracing technique in both eyes of 3 16 emmetropic and moderately myopic school children and young adults. Myopic Subjects were found to have greater mean root mean Square (RMS) value of wavefront aberrations than emmetropic subjects. Emmetropic adults had the smallest mean RMS. which remained smaller than the values for myopic adults and children and for emmetropic children both when second order Zernike aberrations (astigmatism) and third order Zernike aberrations were removed. Twenty percent of myopic adults had RMS values greater than values for all of the emmetropic adults. with significantly greater values for Zernike aberrations from second to seventh orders. High amounts of wavefront aberrations. which degrade the retinal image. may play a role in the development of myopia.; Wavefront aberrations were measured using a psychophysical ray-tracing technique in both eyes of 3 16 emmetropic and moderately myopic school children and young adults.
