Primary Outcome
Visual acuity (VA) is a measure of the spatial resolution of the visual processing system. Visual acuity will be measured in each eye and measured as ≤20/40 or \>20/40. Since there are two best corrected distance visual acuity measurements per person (right eye and left eye), the visual acuity in the worse eye will be used in the analysis and reported at the patient level, rather than the eye level. Visual acuity analysis will be handled as a dichotomous variable and the proportion of subjects w
