Recurrent corneal erosion (RCE ) is a common ocular disorder characterized by a disturbance at the level of the corneal epithelial basement membrane (BM), resulting in defective adhesions and recurrent breakdown of the epithelium.5 RCE may occur spontaneously or secondary to corneal
injury. Predisposing factors include diabetes or corneal dystrophy.6 Patients with RCE often show increased levels of enzymes such as matrix metalloproteinases (MMPs) that dissolve the BM and its anchoring components including integrins, laminin, and type VII collagen.7
