Stress-strain behavior of the (A) normal and (B) RGE chicken corneas, derived from pressure-rise data during the fourth cycle of inflation, using mathematical back-analysis that corrects for the effects of corneal geometry and thickness. Here stress represents the average internal force per unit area acting on the tissue's cross section, while strain is defined as the ratio between the tissue's stretch and initial dimension.
