Located on the inner side of the cornea is a very sensitive layer of cells called the ENDOTHELIUM. These cells transfer nutrients from the aqueous humor into the cornea while pumping out waste products and excess water. This is a vital function because if the water content of the cornea is not maintained at precisely the right level, the cornea will become cloudy and can result in a serious reduction in vision. Endothelial cells do not regenerate, so great care must be taken to protect these cells. (see Bullous Keratopathy, for more information)
