 Carson participated in four subsequent high-risk conjoined twin separations, including a 1997 operation on craniopagus Zambian twins, Joseph and Luka Banda, which resulted in a normal neurological outcome.Two sets of twins died, including Iranian twins Ladan and Laleh Bijani; another separation resulted in the death of one twin and the survival of another, who is legally blind and struggles to walk.According to the "Washington Post", the Binder surgery "launched the stardom" of Carson, who "walked out of the operating room that day into a spotlight that has never dimmed", beginning with a press conference that was covered worldwide, which created name recognition leading to publishing deals and a motivational speaking career.
