^*From the postoperative three-exponential fit (model 0) and preoperative fits according to models 0 to 4, as well as P values for the paired t-tests of the pre- versus postoperative fits in the center, inner, and outer ring and full circle of the ETDRS grid. Bonferroni correction for multiple testing was applied to the P values.
