Muhammad ibn Aslam al-Ghafiqi (died 1165) was an Andalusian Arab[1] oculist and author of The Right Guide to Ophthalmology (Al-Murshid fi ’l-Kuhhl).
The book shows that the physicians of the time had a complex understanding of the conditions of the eye and eyelids, which they treated with many different surgical procedures, ointments, and chemical medicines.[2]
