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.
People started experimenting with color photography in the 1840s. Within about 10 years, Levi Hill had worked out a complicated process, with other, more successful processes following. A big shift occurred in 1935, when Kodak brought out Kodachrome, initially as a 16mm color film for home movies (slide film followed). The following year, Agfa brought out Agfacolor Neu, which improved on Kodachrome with a dye coupler technique.
