| Summary: | Data on the mechanical properties of the lens capsule available in the literature are limited, providing only global and 1-D information. There has yet to be any systematic, rigorous study of the nonlinear multiaxial biomechanics of the lens capsule. First and foremost, there is a need to delineate the general characteristics of the lens capsule and to identify any regional differences that may exist. Thus, the goal of this work was to design and construct an experimental system to load the lens capsule multiaxially in its intact, native configuration and to quantify the general characteristics via pressure-strain data. This experimental system alters the stresses in the normal porcine anterior lens capsule, thereby allowing local displacement gradients and, in turn, deformation gradients to be calculated. Such data are needed to compute the multiaxial strain fields. In this study, cyclic inflation tests were performed over pressures ranging from P = {0, 45 mmHg}, and creep tests were performed at a constant inflation pressure P = 45 mmHg. |
