| 摘要 | The biomechanical characteristics of porcine corneal stroma along the depth of cornea in different anatomical orientations were experimentally investigated and quantitatively analyzed. The porcine corneal stroma tested here was cut mechanically into the three layers along the thickness of the cornea for the first time. Based on the convenient uniaxial tensile extensometry, the Young's moduli of each stromal layer in different anatomical orientations were proved to be equal to each other. By virtue of testing the mechanical behaviors of the different layers, the Young's moduli of the stromal layers were found to decrease gradually from the anterior to posterior corneal surface. Thus, the stroma was proved to be mechanically transversely isotropic. Furthermore, based on the analysis of the experimental data, the change of stromal Young's modulus along the depth of the cornea was determined to be linear and equal to - 2.79 +/- 0.967 MPa/mm from the anterior to posterior corneal surface. Finally, the linear gradient characteristic of the stroma was appropriately explained by virtue of stromal microstructures. |
