Abstract

Purpose: : Analyze and compare the total and corneal aberrations between the normal group and the keratoconus suspect eyes group.

Methods: : We analyzed and compared the aberration values up to the 6th order of Zernike polynomials of 108 normal eyes (N) and 40 eyes suspects of keratoconus (KS) classified by Nidek Corneal Navigator®.

Results: : The total aberrations do not show the significant difference, but we found the difference for the next terms of corneal aberrations: vertical coma, N = -0.081 ± 0,17, KS = -0.339 ± 0.22, p = 0.007, horizontal coma N = 0.072 ± 0.13, KS = -0.156 ± 0.49, p = 0.029, spherical aberration, N = 0.237 ± 0.07, KS = 0.057 ± 0.04, p = 10-5.

Conclusions: : The anomalies related to the suspect forme of keratoconus seem to be more sensible in analysis of the ocular surface deformation than those of total ocular wave front.
