Effects of storage time on the mechanical properties of rabbit peripapillary sclera after enucleation

Academic Article

Abstract

  • In the field of biomechanics, little research has been performed to evaluate the effect of storage time on the material properties of ocular tissues. Twenty-four rabbit eyes were divided into six groups with storage times from 3 to 72 hr. A tensile specimen was prepared from the inferior quadrant of each sclera and was subjected to a stress relaxation test. The data were analyzed using linear viscoelastic theory yielding four material parameters (E0, instantaneous elastic modulus; E∞, equilibrium elastic modulus; β, half-width of the Gaussian distribution; τm; mean relaxation time). No statistically significant differences were found in the material properties of each group, which suggests that sclera can be stored up to 3 days without risking mechanical deterioration.
