Charles Deval

For a few years he studied with Frédéric Jules Sichel, and in 1839, he started his own practice.

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.

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.
