摘要:Purpose To compare the refractive measurements from a wavefront aberrometer, autorefractor, and retinoscopy after cycloplegia in evaluating the usefulness and validity of refractive measurements by a wavefront aberrometer in children. Methods A total of 130 eyes of 65 children, aged from 3 to 16 years, were examined using retinoscopy, a wavefront aberrometer (OPD-Scan III), and an autorefractor (KR-1) after cycloplegia. Refractive measurements were converted to power vectors (M, J 0 , and J 45 ) and cylindrical absolute values for statistical analysis. The agreement between instruments was assessed and the correlations of measurements were evaluated. Subgroup analysis was performed on two subgroups: one representing less refractive error (|M| < 2 D on cycloplegic retinoscopy) and the other with larger refractive error (|M| ≥ 2 D on cycloplegic retinoscopy). Results Compared with retinoscopy readings, the aberrometer and autorefractor yielded more myopic values ( p = 0.007, p < 0.001). In the less refractive error group, the autorefractor results showed statistically significant differences from retinoscopy readings for M, J 0 , and J 45 and the cylindrical absolute value (all p < 0.05); there were no statistically significant differences between M, J 0 , and J 45 vectors of the aberrometer and those obtained using retinoscopy ( p = 0.674, p = 0.699, p = 0.766). With the larger refractive error group, the M vectors of the aberrometer and autorefractor showed more myopic values than the M vector retinoscopy readings; the differences were statistically significant (all p < 0.001). Conclusions The wavefront aberrometer yielded refraction readings closer to those obtained with retinoscopy than the automated refraction in the less refractive error group. With a larger refractive error, statistically significant differences (all p < 0.001) were found among the aberrometer, autorefractor, and retinoscopy readings.
