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 …

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

A mechanical model of the human cornea is proposed and employed in a finite element
formulation for simulating the effects of surgical procedures, such as radial keratotomy, on …

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 …

Experimental data on the mechanics of human cornea is meager and sometimes flawed.
Moreover, questions regarding the correct material symmetry and the role of the fibrous …

The optical characteristics of the human cornea depends on the mechanical balance
between the intra-ocular pressure and intrinsic tissue stiffness. A wide range of ophthalmic …

The cornea is responsible for about seventy percent of refractive power of the eye and
transmits more than ninety percent of the incident light. The refractive power and …

PURPOSE: To optimize the construction details of corneal numerical models while
maintaining efficiency and reliability of predictions. METHODS: Nonlinear finite element …

Purpose: To determine the biomechanical deformation of the cornea resulting from tissue
cutting and removal by use of a new computational model and to investigate the effect of …

Organized collagen fibrils form complex networks that introduce strong anisotropic and
