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.
 Boulevard du Temple , a daguerreotype made by Louis Daguerre in 1838, is generally accepted as the earliest photograph to include people. It is a view of a busy street, but because the exposure time was at least ten minutes the moving traffic left no trace. new era in color photography began with the introduction of Kodachrome film, available for 16 mm home movies in 1935 and 35 mm slides in 1936.
