Comparison of Two Wavefront Autorefractors: Binocular Open-Field versus Monocular Closed-Field
Table 2
Mean values of mean spherical equivalent (MSE), cylindrical components (J0 and J45), and binocular corrected distance visual acuity (BCDVA) obtained with both binocular open-field (eye refract) and monocular closed-field (VX110) autorefractors.
