Distributions of total, anterior, and posterior corneal SAs in different groups.

Groups	SAs	Minimum (μm)	Maximum (μm)	Mean ± SD (μm)
Aniso, longer (N = 489)	Total cornea	−0.118	0.742	0.303 ± 0.120
	Posterior corneal surface	−0.235	−0.016	−0.128 ± 0.034
	Anterior corneal surface	−0.102	0.768	0.334 ± 0.116
Non, longer (N = 597)	Total cornea	−0.133	0.687	0.295 ± 0.151
	Posterior corneal surface	−0.229	−0.021	−0.132 ± 0.034
	Anterior corneal surface	−0.180	0.751	0.331 ± 0.148
Aniso, shorter (N = 489)	Total cornea	−0.365	0.681	0.306 ± 0.125
	Posterior corneal surface	−0.224	−0.011	−0.128 ± 0.035
	Anterior corneal surface	−0.286	0.695	0.337 ± 0.118
Non, shorter (N = 564)	Total cornea	−0.154	0.702	0.293 ± 0.117
	Posterior corneal surface	−0.223	−0.018	−0.131 ± 0.035
	Anterior corneal surface	−0.099	0.698	0.328 ± 0.112

SAs = spherical aberrations; Aniso = aniso-axial length group; Non = non-aniso-axial length group; shorter = shorter set; longer = longer set; SD = standard deviation. The values of total posterior and anterior corneal SAs with analyses of variance were >0.05 among the four groups. One non-aniso-axial length eye in the longer set with anterior corneal SA = 2.767 μm, posterior corneal SA = −0.097 μm, and total corneal SA = 2.748 μm was considered abnormal and was not listed as the maximum.
