Wiens, who has endured over 20 surgeries since the accident, said he agreed to the facial transplant procedure for his 3-year-old daughter, Scarlett.
"I could have lived like I was, no problem, if I did not have my daughter," Wiens said in the interview. "But I could not bear the thought of her growing up and being asked questions, 'Why does your daddy look different?' And dealing with that all of her childhood."
The 26-year-old construction worker from Fort Worth, Texas, suffered fourth-degree burns leaving him almost completely without facial features in November 2008 when his head came in contact with a high-voltage power line.
The remarkable operation, carried out in March at Brigham and Women's Hospital, gave Wiens a new nose, skin, lips, muscle and nerves from an unidentified deceased person. The transplant procedure required 15 hours of work by 30 specialists.
Wiens also spoke with the general media for the first time since his operation at a press conference held this morning.
