We read with interest the use of keratoconic donor corneas for elective endothelial keratoplasty and emergency penetrating keratoplasty. Collagen cross-linking (CXL) treatment is the current gold standard for imparting biomechanical stability in keratoconus. CXL has also been done to strengthen the donor cornea used as carrier graft for Boston keratoprosthesis to avoid sterile melts. 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.,
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.
