Eva Joyce is the youngest Brit to have a corneal transplant when she was 17-days old.

For 6-weeks after the operation Eva was given hourly eye-drops. Eva is still given anti-rejection drugs to reduce the risk of her body failing to accept the donor corneas.Eva has to keep a follow-up at the hospital every fortnight. She will be monitored till she is 16-years old.
Consultant ophthalmologist Manoj Parulekar said, "We look forward to seeing her grow up and do all the things her friends and big sister can do."
Eva's mother said, "We would like to highlight the importance of corneal donation and the huge difference that it can make to people's lives. We feel incredibly lucky that someone has made the decision to donate organs to help people like Eva in what must be extremely sad circumstances."
