Experimental tests on human corneas reveal distinguished reinforcing collagen lamellar
structures that may be well described by a structural constitutive model considering …

The human cornea (the external lens of the eye) has the macroscopic structure of a thin
shell, originated by the organization of collagen lamellae parallel to the middle surface of the …

A numerical model based on continuum mechanics theory has been developed which
represents the 3D anisotropic behaviour of the corneal stroma. Experimental data has been …

We have applied wide-angle X-ray scattering to the human cornea in order to quantify the
relative number of stromal collagen fibrils directed along the two preferred corneal lamellar …

Organized collagen fibrils form complex networks that introduce strong anisotropic and
highly nonlinear attributes into the constitutive response of human eye tissues. Physiological …

Examining the cross-section of the human cornea with second harmonic-generated (SHG)
imaging shows that many lamellae do not lie parallel to the cornea's anterior surface but …

Fibrillar collagen in the human cornea is integral to its function as a transparent lens of
precise curvature, and its arrangement is now well-characterised in the literature. While …

Purpose.: To characterize and quantify the collagen fiber (lamellar) organization of human
corneas in three dimensions by using nonlinear optical high-resolution macroscopy (NLO …

A network of circumferentially oriented collagen fibrils exists in the periphery of the human
cornea, which is thought to be pivotal in maintaining corneal biomechanical stability and …

Purpose.: To develop a mechanical model with which to investigate the relationship
between the crimping morphology of collagen fibrils and the nonlinear mechanical behavior …
