Linear regression demonstrating the strongest predictors of preoperative-to-postoperative strain change (rather than absolute strain) across all preoperative and myopic surgical simulations. A) Residual stromal bed (RSB) thickness (R-squared = 79.7%, P<.001) and B) percent stromal tissue altered (PSTA, R-squared = 95.6%, P<.001). In the context of preoperative cases, RSB refers to the total (unaltered) stromal thickness and PSTA = 0%.
