Corneal epithelial defects according to AD grading. After 7 days of instillation, corneal epithelial defects were observed in eight eyes of the subjects receiving MFLX and seven eyes of the subjects receiving LVFX. AD grading of the 15 eyes was A1D1 for 14 eyes and A2D1 for the remaining eye. No statistically significant difference between the groups was observed in the incidence of epithelial defects (P = 0.675, t-test).
