Louis-Auguste Desmarres

Louis-Auguste Desmarres (1810-1882) was a French ophthalmologist who practiced medicine in Paris. After earning his medical degree he was an assistant to Frédéric Jules Sichel (1802-1868). One of Desmarres' better known assistants was Swiss ophthalmologist Johann Friedrich Horner (1831-1886).

Desmarres was one of the better known ophthalmic surgeons in 19th century France, and is remembered today for an important textbook on diseases of the eye called Traité théorique et pratique des maladies des yeux. In 1850 he introduced a surgical procedure for pterygium. Today, there are numerous surgical intruments that bear his name, including Desmarres curved lid retractor, Desmarres corneal dissector and Desmarres chalazion forceps.
