The cornea provides the majority of the eye’s refractive power and is the most important ocular determinant of retinal image quality. The refractive power of the cornea derives from its shape, and this shape is a function of the ocular biomaterial properties and loading forces such as the intraocular pressure (IOP). Finite element analysis has been explored as a tool for estimating the refractive outcomes of corneal interventions such as laser in-situ keratomileusis (LASIK) and photorefractive keratectomy (PRK)[1].
