The ratio of the AP-length to the ED of the lenses presented in Tables 1 and 2 are compiled as a measure of the changes in lens “circularity” under the imposed anisotonic conditions.

^*Value significantly greater than the initial control value at beginning of experiment, 0.769 (P< 0.03, as paired data).

^**Value significantly greater than its respective antecedent (P< 0.001, as paired data).
