The optical function of cornea is closely associated with its morphological structure. Abnormal corneal morphology can lead to myopia, hyperopia and keratoconus. It is an important subject to study the corneal mechanical characteristics. The result will improve the understanding of corneal surgery and predict postoperative through establishing the biomechanical model with clinical application. In this paper, based on the research work of the ophthalmic biomechanics team of Capital Medical University, we review the corneal biomechanical testing methods and the corneal constitutive parameter research.
