Who was Karl Koller?

Karl Koller was an Austrian ophthalmologist who began his medical career as a surgeon at the Vienna General Hospital, and was a colleague of Sigmund Freud.

Koller introduced cocaine as a local anaesthetic for eye surgery. Prior to this discovery, he had tested solutions such as chloral hydrate and morphine as anaesthetics in the eyes of laboratory animals without success. Freud was fully aware of the pain-killing properties of cocaine, but Koller recognized its tissue-numbing capabilities, and in 1884 demonstrated its potential as a local anaesthetic to the medical community. Koller's findings were a medical breakthrough. Prior to his discovery, performing eye surgery was difficult because the involuntary reflex motions of the eye to respond to the slightest stimuli. Later, cocaine was also used as a local anaesthetic in other medical fields such as dentistry. In the 20th century, other agents such as Xylocaine have replaced cocaine as a local anaesthetic.

In 1888, Karl Koller moved to the United States and practiced ophthalmology in New York. He received many distinctions in his career, including being honored by the American Ophthalmological Society as the first recipient of the "Lucien Howe Medal" in 1922. This award is given to physicians in recognition of outstanding achievements in ophthalmology. In 1930 he was also honored by the Medical Association of Vienna.
