The aim was to assess the agreement in the measurement of ocular aberrations between a new Adaptive Optics Vision Analyzer (AOVA, Voptica, Murcia, Spain) and a commercial aberrometer (KR-1 W, Topcon, Tokyo, Japan), both based on the Hartmann-Shack technique.


 Although the largest mean differences were obtained for the defocus coefficient C(2,0) and the spherical equivalent (M) with a mean difference (and standard deviation) of 0.190 ± 0.099 µm and -0.150 ± 0.188 D, respectively, they were clinically acceptable and significant correlations were found between the AOVA and KR-1 W for the major refractive components such as spherical equivalent (r = 0.995, p < 0.001), J0 (r = 0.964, p < 0.001), J45 (r = 0.901, p < 0.001) and C(4,0) (r = 0.575, p = 0.001).
