Mario Teran was the Bolivian Army sergeant who executed Marxist revolutionary Che Guevara as a young man on October 9, 1967.
In 2006, Teran was treated for cataracts by Cuban physicians in the Cuba-Venezuela Operacion Milagro (Operation Miracle) program, which restored his sight.
This was first revealed when Teran's son wrote a letter to the Santa Cruz de la Sierra newspaper El Deber thanking the Cuban doctors. In 2007 Granma opined on the treatment, stating:
"Cubans Treat Man Who Killed Che"
"The Curse Of Che Guevara"
"Cuban Doctors Restore Sight of Che's Killer"
