Data were compared using t-tests and are expressed as the mean ±SD deviation except when otherwise stated.
*Compared using the χ2 test.
CCT, central corneal thickness; CDVA, corrected distance visual acuity; logMAR, logarithm of the minimum angle of resolution; PTA, percentage of tissue altered; SE, spherical equivalent; UDVA, uncorrected distance visual acuity.
