Aw, c’mon, doesn’t “Un Chien Andalou” count for ophthalmology?
Magnificent Obsession, starring Jane Wyman and Rock Hudson.
Hudson’s a playboy, partly responsible for her husband’s death… Years later, Wyman goes blind, and well… he sees her again and falls in love with her… only she doesn’t know it’s really him, 'cause she’s blind… So he changes his ways… and devotes his life to finding a cure for her blindness… and… and…
Well, I don’t know if Hudson plays an Ophthalmologist or not, but there are lots of eye tests and whatnot. And it’ll make you cry.
