'Ali ibn 'Isa was a notable oculist (kahhal) of Baghdad whose life falls in the first half of the 11th century. His main work is Tadkirat Al-kahhalin (Manual for Oculists or Note-book of the Oculists). It is the classical handbook of Muslim ophthalmology, translated once into Hebrew and twice into Latin, and was printed with the title of Tractatus de oculis Jesu Halis in Venice in 1497, 1499 and 1500. It is the oldest Muslim work on ophthalmology that is complete and survives in the original state.
