Legally blind archer Im Dong-hyun broke the world record in the 72-arrow mark with 699 points and led South Korea to a team record in the ranking round at the London Olympics on Friday.
Im has 10% vision in his left, 20% in his right eye.
"This is just the first round, so I will not get too excited by it," Im said.
He combined with Kim Bub-min and Oh Jin-hyek as South Korea scored 2,087 points Friday, breaking the old mark of 2,069 set by South Korea in May.
Im won gold medals in the team event at the 2008 Beijing and 2004 Athens Olympics.
Im has said that when he looks at the targets, he sees colors with blurred lines and aims by distinguishing between the bright colors of the target.
