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.
There were many attempts during this time at capturing color photography, however, in 1861, physicist James Clerk Maxwell would create the world's first permanent color image. One of the early methods of taking color photos was to use three cameras. Each camera would have a color filter in front of the lens. This technique provides the photographer with the three basic channels required to recreate a color image in a darkroom or processing plant. The first color film, Autochrome, did not reach the market until 1907 and was based on dyed dots of potato starch.
