Central Corneal Sensitivity Suffered a Modest Reduction but Recovered to the Baseline Level during the 3-Month Treatment The significant differences observed from baseline to 3 months after treatment were as follows: (1) central corneal sensitivity suffered a reduction in 1 month after treatment ( F = 3.009, P =0.039) but returned to the baseline level at the final visit ( Figure 1(a) ), while changes in temporal corneal sensitivity were not statistically significant ( F = 2.462, P =0.074) but showed a trend similar to that of central corneal sensitivity ( Figure 1(b) ); (2) a significant reduction occurred in SE ( F = 106.499, P < 0.001), Km ( F = 39.960, P < 0.001), and E value ( F = 18.124, P < 0.001), while a remarkable improvement was found in UCVA ( F = 67.776, P < 0.001) and SRI ( F = 21.260, P
