Dear Editor:
We read with interest the use of keratoconic donor corneas for elective endothelial keratoplasty and emergency penetrating keratoplasty.[1] Collagen cross-linking (CXL) treatment is the current gold standard for imparting biomechanical stability in keratoconus.[2] CXL has also been done to strengthen the donor cornea used as carrier graft for Boston keratoprosthesis to avoid sterile melts.[3] We and others have demonstrated fortification of the donor cornea with preoperative CXL to prevent recurrent infection in therapeutic penetrating keratoplasty done for infective keratitis.[4],[5]
We wish to point out that cross-linking may similarly be performed on a keratoconic donor cornea which has to be used for full-thickness transplant in exigent situations. This may help confer biomechanical stability when grafted in the host eye.
