People in Korea now have access to the most advanced treatment for tumors in the eye.
Gangnam Severance Hospital is treating eye tumors with contact radiation therapy.
With this method, it's not necessary for the eye to be removed to be treated.
A radioactive isotope of ruthenium is used to irradiate the tumor and remove it.
The treatment doesn't hurt a person's eyesight as much, and recovery only takes about a week.
It's also covered by Korea's national health insurance.
