Criteria Used for Inclusion of Subjects in Each of the Four Groups of Anisometropia, Based on Clinical Notation Calculation of SE and Cylinder Anisometropia

		Cylinder Anisometropia
SE Type	Amount of SE Anisometropia	<0.25 D	0.25 to <1.00 D	≥1.00 D
As indicated, for the analyses, some subjects were included in both the SHA and CA groups and some were included in both the SMA and CA groups. Categories indicated by the blanks were not included in analyses. ISO, isometropic group; SHA, spherical hyperopic anisometropia group; SMA, spherical myopic anisometropia group; CA, cylinder anisometropia group.
Hyperopic SE in both eyes	<0.25 D	ISO	CA	CA
	0.25 to <1.00 D	SHA	SHA, CA	CA
	≥1.00 D	SHA	SHA	-
Myopic SE in both eyes	<0.25 D	ISO	CA	CA
	0.25 to <1.00 D	SMA	SMA, CA	CA
	≥1.00 D	SMA	SMA	-
Other	<0.25 D	ISO	CA	CA
	0.25 to <1.00 D	-	CA	CA
	≥1.00 D	-	-	-
