RESUMO
PURPOSE: To report a case of corneal scarring following collagen cross linking in a young female. METHODS: A 24-year-old female presented to us with complaints of decreased vision and a white spot in her left eye following collagen cross linking (CXL) performed elsewhere, four years prior. We diagnosed her as a case of left eye leucomatous corneal opacity for which she underwent optical penetrating keratoplasty under local anaesthesia. The excised corneal tissue was evaluated by routine histopathology and immunohistochemistry. RESULTS: At the final follow up visit, one year following corneal transplantation, her visual acuity improved to 20/20, J1 with a clear graft. CONCLUSION: Vision threatening corneal scarring may be rarely noted following CXL.
