| 1 - Corneas |
 |
DEFINITION, CHARACTERISTICS AND HOW THEY ARE OBTAINED
This is the cornea, with a scleral ring approximately 1 mm in size, obtained from an eyeball from a deceased tissue donor or a multi-organ donor in a state of brain death.
The density of the endothelial cells, found in the innermost cornea layer, is a determining factor for a successful transplant. |

RESULTS OF STUDIES AND ANALYSIS
• Macroscopic examination: The presence of an arcus senilis, epithelial damage (erosions and ulcers), as well as corneal transparency, are evaluated and noted in the report sent to the doctor implanting the tissue.
• Examination with a clinical specular microscope. The endothelium, which must have a minimum density of 2000 cells/mm, is analysed 2.
• Surface antigen of the HBsAg hepatitis virus: negative.
• Hepatitis C virus antibodies (Anti-HCV): negative.
• Human immunodeficiency virus anti-bodies (Anti-HIV 1/2): negative.
• Lues serology: negative
• HCV RNA (PCR): negative.
