Values are mean ± SEM (range). Patients underwent bilateral femtosecond laser-assisted in situ keratomileusis (FS-LASIK surgery) followed by application of a bandage contact lens (BCL) to one eye (BCL eyes) but not the other (control eyes). F/M, female/male; R/L, right/left eye; D, diopters; BCVA, best-corrected visual acuity; IOP, intraocular pressure; CCT, central corneal thickness; UCVA, uncorrected visual acuity.
