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.
Modern History. When you think of photography, you may think of it as a fairly modern invention. On the contrary, photography began with the camera obscura as early as the 10th century AD, and some evidence seems to indicate that Aristotle was familiar with this technique as early as the 4th century BC.The camera obscura was a darkened room with a tiny hole in one wall with a white screen on the opposite wall.n the early 1800s, the camera obscura had become a portable, light-tight box that contained materials and chemicals that would momentarily record the image through the lens. Cameras created in the 1800s were often crafted for looks as well as functionality.
