Notes: Group A received cyclosporine A treatment, initiated at 1 month following LASIK; group B served as a control group. The P-values in this table were not statistically significant (P<0.05). There is no statistically significant difference in preoperative patient demographical data between the two groups (Group A & Group B).
Abbreviations: CDVA, corrected distance visual acuity; CET, central epithelial thickness; MRSE, mean refractive spherical equivalent; TVT, topographic epithelial thickness variability; TBUT, tear film break-up time; UDVA, uncorrected distance visual acuity.
