Abstract

Cornea is the front window of eye, and assessing its health is important to detect any abnormalities and treating early. Until now, information on how human eye elements distribute shear stress remained scarce. In a research study conducted recently, diamondshaped stress concentration patterns on a healthy human cornea have been revealed (Figure 1). Unlike scanning the internal structures of the human body using X-ray, this new approach [1,2] for measuring stress distribution on human cornea does not require the use of X-ray and is therefore friendlier to the biological elements of cornea. Furthermore, the stress measurements on cornea can be made in-vivo, by using a non-invasive method employing white light source.
