Bentiu State Hospital Medical Director, Simon John Deng, said the surgeons will stay for three days only and that another eye campaign will be done next January, Internews reported.
Joseph Biliew Gai, who lost his job two years ago due to his eye problem, is waiting for his operation.
He said he was optimistic about his economic future after the success of the operation.
The organization plans to operate 40 patients with eye problems that do not have access to a specialized eye hospital.
