Twenty five years later, Giáp has come to Australia for the 25th anniversary of the Fred Hollows Foundation, a charity set up by Dr Hollows and his wife, orthoptist Gabi, in 1992 - before Dr Hollows passed away from metastatic renal cancer in February the following year.
Giáp said the sight-restoring surgery motivated him to contribute to society and he became the first in his family to graduate from Hong Duc University in Thanh Hoa, about 150 kilometres south of Hanoi, where he studied to become a mathematics schoolteacher.
