Numbers indicate p values, when significant deficits relative to the NonA group were present, “ns” indicates vision not significantly reduced (relative to NonA group), and “—“ indicates that test was not conducted (in cases in which deficits were not significant at baseline). Results by cohort presented only in cases in which cohort interacted significantly with astigmatism group.

Numbers indicate p values, when there is significant improvement relative to improvement in the NonA group, and “ns” indicates no significant improvement (relative to NonA group). Results by cohort presented only in cases in which cohort interacted significantly with both “time” and “astigmatism group” variables (i.e., only when improvement differed significantly across astigmatism group and cohort). Cells are merged across orientation in cases in which stimulus orientation did not interact with both “time” and “astigmatism group” variables (i.e., improvement was not dependent upon stimulus orientation).
