Radial keratotomy: An eye surgery procedure designed to flatten the cornea, reducing its optical power, to correct nearsightedness (myopia). In the procedure, incisions (cuts) are made in the cornea. The procedure is said to be radial because the incisions resemble the spokes in a bicycle wheel.
Slinky Dog (better known as Slinky and often called Slink or Slinkykins) is a supporting character in the Toy Story franchise. He is a toy dachshund with a graveled Southern accent.
The dog on Petticoat Junction was never called by his name. They simply called him Dog. In real-life, the dog's name was Higgins. You might remember him better from his final acting role as the star of the 1974 movie, Benji.
