Comparisons of predicted and observed creep in corneal epithelium (A), endothelium (B), and stroma (C). Coefficients of determination for all four trials consistently exceeded 0.94 and 0.98 for epithelial specimens, at 5.5- and 19.0-μN loading forces, respectively. Coefficients of determination exceeded 0.98 and 0.96 for endothelium at 632 and 1310 pN, respectively, and exceeded 0.98, and 0.96 for stroma at 19.0- and 30.0-μN loading, respectively.
