Cornea modelling

Customized Finite Element Modelling of the Human Cornea

AIM To construct patient-specific solid models of human cornea from ocular topographer data, to increase the accuracy of the biomechanical and optical estimate of the changes in refractive power and stress caused by photorefractive keratectomy (PRK). METHOD Corneal elevation maps of five human eyes were taken with a rotating Scheimpflug camera combined with a Placido disk before and after ref...

Finite element modelling of cornea mechanics: a review.

The cornea is a transparent tissue in front of the eye that refracts light and facilitates vision. A slight change in the geometry of the cornea remarkably affects the optical power. Because of this sensitivity, biomechanical study of the cornea can reveal much about its performance and function. In vivo and in vitro studies have been conducted to investigate the mechanics of the cornea and det...

Cornea

This book, with contributions by some distinguished ophthalmologists, neatly summarizes some of the recent advances in corneal diseases and their management. The opening chapter by Dua and Said, is an appropriate introduction to the book, dealing as it does with the fundamental basics of ocular health – the tear film, conjunctiva, the limbus with its reservoir of stem cells and corneal nerves. ...
