Are there different options for incisions with cataract surgery? In 2012 the FDA approved the first laser designed to be used during cataract surgery. Laser cataract surgery makes very precise incisions in the cornea using laser technology. The laser then makes a perfectly circular opening on the lens surface. The same small ultrasound probe used in regular cataract surgery is then used to liquefy and remove the cloudy cataract lens. Astigmatism treatments can also be performed with a laser (limbal relaxing incisions).
See: Louis Arthur Ducos du Hauron. The first widespread, successful color photography process was the autochrome, which was invented by Auguste and Louis Lumiere, patented in 1903 and commercially produced by 1907.
The first permanent color photograph was made in 1861 by James Clerk Maxwell. Earlier attempts resulted in color photographs whose colors faded rather quickly. ****************. The first color plate, Autochrome, invented by the French LumiÃ¨re brothers, reached the market in 1907. It was based on a 'screen-plate' filter made of dyed dots of potato starch, and was the only color film on the market until German Agfa introduced the similar Agfacolor in 1932.
