Charles Deval (December 6, 1806 – April 9, 1862) was a French ophthalmologist born in Constantinople, He was the son of dragoman Constantin Deval (1767-1816). He practiced medicine in Paris, where he studied under Frédéric Jules Sichel (1802-1868).
Deval is largely remembered for his written works on ophthalmic medicine, particularly the 1844 Traité de Chirurgie Oculaire, which was only the second French work devoted exclusively to eye surgery. This book was important because it helped introduce German and Austrian ophthalmic practices into French medicine. Prior to this publication, descriptions regarding methods of ophthalmological surgery practiced in these countries were not yet available in the French language. This book was a result of Deval's studies in Vienna with Friedrich Jäger von Jaxtthal (1784-1871) and Anton von Rosas (1791-1855). Included in his treatise were explanations of medical innovations developed by German surgeons Louis Stromeyer (1804-1876) and Johann Friedrich Dieffenbach (1792–1847).
Another important written work by Deval was the 1862 Traité théorique et pratique des maladies des yeux, which was a treatise on diseases of the eye, and a culmination of his experiences working with over 20,000 cases in ophthalmic medicine. (Note: Deval's treatise is not to be confused with Louis-Auguste Desmarres' 1847 "Traité théorique et pratique des maladies des yeux").[1]
