Corneal Hysteresis and its relevance to the Eye

Main Article Content

Francis Carbonaro, MD PhD FRCOphth


Together with the tear film, the cornea is the first optical interface of the visual system and is responsible for about 80% of the refractive convergence power of the eye, determining whether a person is emmetropic, myopic or hyperopic. It also acts a barrier against trauma and microbes. The cornea is often described as the “window to the eye”.
