LASIK surgery was invented by accident. In 1993, a grad student at the University of Michigan forgot to wear his safety glasses while checking on an experimental femtosecond laser, and took a blast of laser directly to his eye. However, he suffered no pain or ill effects. The doctor who examined him got curious about the laser, and contacted the physics department. This led to LASIK surgery, where a laser re-shapes the cornea to improve vision.
