A recurrent corneal erosion is a recurring opening or breakdown of the cells on the top layer of the cornea. The cells that make up the top layer of the cornea are called epithelial cells. These epithelial cells are bound tightly to the cornea by the layer underneath, called the Bowman’s layer. Bowman’s layer functions like glue to hold the epithelial cells tightly to the eye. The Bowman's layer is made of collagen. When this layer is damaged or unhealthy, the top layer of epithelial cells fail to heal properly and never bind correctly to Bowman’s layer. As a result, the epithelial cells come off easily. Epithelial cells regenerate but they are poorly anchored to Bowman’s layer. From...
