Charles R. Munnerlyn changed the world’s concept of vision when he designed the first digital device for automatically determining refractive errors in the human eye. Known as one of the founding fathers of laser vision correction, he ushered in one of the fastest growing surgeries performed in the United States – used on more than 1. 4 million eyes in 2001 alone. That first invention also ushered in Munnerlyn’s entrepreneurial spirit. After years of toil and millions of dollars in investments, he and a small group of engineering and medical colleagues founded VISX, a company that is now the world’s largest manufacturer of laser-based vision correction systems.
