文摘

Detailed development of a modified Rayleigh-Lamb frequency equation (mRLFE) model. The mRLFE and OCE can be used to assess corneal viscoelasticity. The mRLFE incorporated the corneal thickness and posterior fluid-structure interface. Viscoelasticity of the untreated and CXL-treated eyes was quantified at various IOPs. Corneal stiffness increased after CXL and was almost linear as a function of IOP.
