Carmen Blandin Tarleton of Thetford, Vermont, right, is embraced by Marinda Righter, daughter of Tarleton's face donor Cheryl Denelli-Righter, at Brigham and Women's Hospital in Boston, Mass., Wednesday, May 1, 2013.

Tarleton is legally blind and read her remarks from a tablet. She thanked Righter's family for what she called "a tremendous gift" that's greatly alleviated the physical pain she'd felt daily.
