Donor selection, retrieval and preparation of donor tissue. Donor selection.
Corneal transplantation safety is widely dependent on clinical donor selection. Donor-to-host transmission of rabies and Creutzfeldt-Jakob disease is well established, and it is lethal for the recipient. Taking into consideration this latter figure, contraindications to ocular tissue transplantation include not only rabies, contact with rabies virus, spongiform encephalitis, family history of spongiform encephalitis, recipients of human pituitary-derived hormones before 1987, surgery using dura mater and brain/spinal surgery before 1992, but also CNS diseases of unknown etiology or those with unknown risk of transmission. It has been established that hepatitis B virus and herpes simplex virus can be transmitted by corneal transplantation, and both diseases are contraindications to transplantation. HIV infection, syphilis, hepatitis C, hepatitis A, tuberculosis, HTLV-1 and -2 infection, active leprosy, active typhoid, smallpox and active malaria are also contraindications to ocular tissue transplantation even if no evidence of donor-to-recipient transmission has been demonstrated. A history of corneal refractive surgery in the donor eye, ocular inflammation, retinoblastoma, and malignant tumors of the anterior segment are contraindications to keratoplasty.
