Visual performance in emmetropia and low myopia after correction of high-order aberrations

Myopic observers may not benefit to the same extent as emmetropes from adaptive optics (AO) correction in a visual acuity (VA) task. To investigate this, we measured AO-corrected VA in 10 low myopes and 9 emmetropes. Subjects were grouped by refractive error. Mean spherical equivalent refractive error was -2.73 D (SEM = 0.35) for the myopes and 0.04 D (SEM = 0.1) for the emmetropes. All subjects had best corrected VA of 20/20 or better. The AO...
