Abstract

The elastic properties of human corneal lamellas with varying degrees of hydration were examined using Brillouin spectroscopy. The findings indicate that hydration significantly influences the elastic properties of the cornea, surpassing the effects of treatments with ultraviolet light or riboflavin. The relationship between the modulus of elasticity and hydration can be described by a two-component model that incorporates the additive contribution of compliance. This model reveals two distinct linear regions, wherein the observed change in slope is attributed to variations in the compliance of collagen, likely resulting from the evaporation of water from the collagen fibrils.

研究人员使用布里渊光谱法检测了不同水合度的人类角膜板层的弹性特性。研究结果表明，水合度对角膜弹性特性的影响很大，超过了紫外线或核黄素治疗的效果。弹性模量与水合作用之间的关系可以用一个包含顺应性加成的双组分模型来描述。该模型显示了两个不同的线性区域，其中观察到的斜率变化归因于胶原顺应性的变化，这可能是胶原纤维中水分蒸发的结果。
