For those of you who don't know of it, I really recommend the novel "The Physician" by Noah Gordon. It tracks the story of a young urban worker's son whose father dies early in early 13th century London and who gets taken as an orphan by a barber (the 13th century's country doctors basically) who teaches him what he knows of basic medicine.
There's a scene later in the book, as he's apprenticing in his English country world, where he meets a jewish doctor who performs a cataract surgery. To this rustic apprentice of a mere barber, this seems like magic. He asks the jewish physician where he learned such a medical marvel and the man explains that he had studied in Al Andaluz, under doctors who had trained in Isfahan in the Caliphate under Ibn Sinna. Without going into too much further detail, the book is absolutely wonderful, especially as the English apprentice meets the legendary Sinna after managing to travel all the way to Isfahan to also study there.
