Cataracts, typically, are actually removed with ultra-sound waves as described above, not with laser light.

What is a cataract?

What is a cataract?The eye is very much like a camera in that they both have a lens that focuses an image onto film. In the eye, the lens is focused using muscles, and the film consists of a thin membrane of nerves that line the inner back of the eye, called the retina. If the lens of your camera were to be smudged or scratched, your pictures would be blurred.

The history of the excimer laser

The excimer laser was developed at IBM in 1976, and used to etch computer microchips. Its extreme precision with negligible damage to adjacent tissue made it a very attractive tool for other applications and in 1983 Stephen L. Trokel, M.D. in cooperation with R. Srinivasa, a physicist, applied it to corneal tissue in a New York Laboratory. The first sighted eye was treated with the excimer laser at LSU in January of 1987. Between 1987 and 1995 numerous laser manufacturers including VISX and Summit Technolog...
