Wave-front aberrations (RMS) of dominant eye and nondominant eye in different groups (Wilcoxon signed ranks; n, valid value, number of pairs).

Anisometropia	Dominant eye (μm)	Nondominant eye (μm)	Z	P
A ≥ 2.5 D (n = 40)	0.237 ± 0.088	0.261 ± 0.149	−0.660	0.543
1.75 D ≤ A < 2.5 D (n = 83)	0.259 ± 0.116	0.262 ± 0.333	−2.590	0.889
1 D ≤ A < 1.75 D (n = 202)	0.227 ± 0.075	0.236 ± 0.085	−2.176	0.660
