title: What is Central Toxic Keratopathy Syndrome if it is not Diffuse lamellar Keratitis Grade IV?
abstract: The Central Toxic Keratopathy (CTK) syndrome describes a rare, acute, self-limited, non-inflammatory process that yields central corneal opacification and significant hyperopic shift after refractive surgery. Despite being exceedingly rare, certain clinical features of CTK give the condition a striking resemblance to other more serious inflammatory conditions, including diffuse lamellar keratitis (DLK). As the authors demonstrate in this article, despite the overlapping clinical features, CTK is a disease process that is distinct from DLK and, therefore, in need of distinct management interventions.
