In this project, the depth-resolved full-field deformation of the porcine cornea under changing intraocular
pressure was investigated by performing digital volume correlation (DVC) on the reconstructed volume images generated
through swept source optical coherence tomography (SS-OCT). Posterior inflation test of porcine cornea sample for two
load steps were performed and the distribution patterns of displacement and strain fields were produced. The error
sources for the measurements were analyzed. The refraction induced OCT image distortion is a main error source for the
measurement results. Then, a methodology was developed to correct the OCT distortion based on the Fermat’s principle.
