Data were derived from ¹independent samples t-test, ²Mann–Whitney U-test, and ³chi-squared test. Continuous variables are reported as mean ± standard deviation. represents statistical significance.^aCCT measured by using Pentacam at corneal vertex. CCT, central corneal thickness; CH, corneal hysteresis; CRF, corneal resistance factor; GAT, Goldmann applanation tonometry; IOP, intraocular pressure; Km, mean keratometry; mm, millimeters; n/a, not applicable; WS, waveform score; y, years; μm, micrometer.
