*p < 0.05 was considered statistically significant. Values are presented as mean ± standard deviation. UDVA: uncorrected distance visual acuity; logMAR: logarithm of the minimum angle of resolution; SER: spherical equivalent; IOP: intraocular pressure; Q:anterior surface asphericity of the cornea; e: eccentricity; CCT: central corneal thickness; K1, K2, Km: corneal curvature; C.HOA: corneal higher-order aberrations at 6.0 mm pupil; C.Sph: corneal spherical aberration at 6.0 mm pupil; C.Coma: corneal coma aberration at 6.0 mm pupil; C.Tre: corneal trefoil aberration at 6.0 mm pupil; SR: strehl ratio.
