The purpose of this study was to measure wavefront aberration between the right and left eyes and to examine the relevance of aberration between them. All coefficients excluding Z4-2 between second and fourth orders of the Zernike showed significant correlation between the right and left eyes. However, coefficients for fifth and sixth orders of the Zernike showed no or extremely low correlation. Defocus (Z20) aberration had extremely high correlation between the right and left eyes with correlation coefficient of 0.908. Spherical (Z40) aberration also showed high correlation with coefficient of 0.820. Astigmatism aberration Z2-2 and Z22 were respectively –0.429 and 0.820. Second astigmatism Z42 had correlation coefficient of 0.484, but Z4-2 did not have significant relevance. Coma aberrations Z3-1 (r = 0.795) and Z31 (r = –0.715) showed high correlation between the right and left eyes. Trefoil aberrations, Z3-3 (r = 0.637) and Z33 (r = –0.510), and tetrafoil aberrations, Z4-4 (r = –0.334) and Z44 (r = 0.386), had significant relationship between the right and left eyes.
