… of acuity from aberrations is the possibility of automated objective measurement of visual
acuity … to minimizing the RMS error of the wavefront) does not provide best acuity. Thus, these …

… on wavefront height, wavefront slope, and wavefront curvature. … a criterion that RMS wavefront
error be <0.25 wavelengths of … of visual acuity (r2 = 0.50) than is RMS wavefront error (r2 < …

… Abstract We determined the degree to which change in visual acuity (VA) … wavefront errors
(WFEs). VA was recorded for five normal subjects reading simulated, logMAR acuity charts …

… The root-mean-square wavefront errors were computed for coma-like aberrations, 3rd to
5th Zernike orders, and total HOAs (3rd to 5th order combined). Contact lens wearers were …

… with visual acuity independent of PD. Here we investigate the correlation between the change
in visual acuity … Visual acuity was recorded for 4 normal subjects using simulated blurred …

… Across modes and within each mode as the level of RMS wavefront error increased above
0.05 μm of RMS wavefront error, visual acuity decreased in a linear fashion. Slopes of the …

… of visual acuity or whether we did not obtain better acuities because the correction of the
wavefront errors … with an increase in visual acuity, we achieved only a reduction of the wavefront …

… In the current study, the positioning errors of the wavefront corrections did not exceed 0.3
mm. The precision in aligning our device was thus sufficient for higher order corrections to …

… referred to as low order wavefront errors and the latter higher order (HO) wavefront errors. …
