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.
A Brief History of Color in Art. Artists invented the first pigmentsâa combination of soil, animal fat, burnt charcoal, and chalkâas early as 40,000 years ago, creating a basic palette of five colors: red, yellow, brown, black, and white. Since then, the history of color has been one of perpetual discovery, whether through exploration or scientific advancement. The invention of new pigments accompanied the developments of art historyâs greatest movementsâfrom the Renaissance to Impressionismâas artists experimented with colors never before seen in the history of painting.
