Solid mechanics models in ophthalmology

Abstract
Solid mechanics-based models have been used in recent years as tools to describe, for example, the stress-strain state of the eye shell to depict the different mechanical aspects of the development of pathological conditions of the eyeball (refractive errors (decreased visual acuity), glaucoma, corneal pathology etc.), to plan and predict the outcomes of ophthalmic surgeries. The talk will review some of these models, focusing on the mathematical models for distinct types of tonometers and differences in the intraocular pressure readings (IOPR) before and after vision correction surgeries. A mathematical model for assessment of the stress-strain state of the cornea after the implantation of the MyoRing rings of varied sizes will also be presented. We will discuss various models to characterize the mechanical properties of human eye tissues, encompassing an orthotropic linearly elastic body model and models depicting nonlinear material behaviour.
