Corneas can be donated up to the age of 85 years. When the doctors believe that a person's brain is dead, extensive tests are carried out to make sure. If the person is a suitable donor, doctors will ask the family to consider organ donation. This is why it's important to tell your family if you want to be an organ donor. There is no pressure placed on families to donate organs.
Families can specify which organs and tissues are donated.
If you have an opinion about this then you should let your family know. Many religions support donation on the grounds that it is a gift of life to another person. If you are in doubt you should talk to your minister, priest or elder. Many people tick 'yes' to become a donor on their driver's licence form. This is an indication of what you want.
