Abstract

Keratoconus is a degenerative, noninflammatory ectasia of the cornea characterized by progressive corneal thinning and irregular astigmatism. Previous investigations have reported decreased mechanical stability in keratoconus corneas compared with normal corneas due to a reduced amount of collagen crosslinks. Collagen Crosslinking (CXL) with riboflavin and ultraviolet- A (UVA) is a proven treatment for arresting the progression of the disease. It consists of polymerization of the stromal fibers with the combined action of riboflavin (a photosensitizing substance) and UVA rays (riboflavin–UVA), which changes the intrinsic biomechanical properties of corneal collagen by increasing its rigidity. Though collagen crosslinking in cases of keratoconus is generally a safe surgery without sight-threatening complications, microbial keratitis after CXL has been reported infrequently. We report a case of Acanthamoeba keratitis after CXL procedure.
