Doctor Lout is old in appearance, with wrinkles on his face and neck. He has grey hair and facial hair. He wears a doctor's lab coat with a pen in one of the pockets. He also wears a light brown shirt with a tie under his doctor's lab coat.
- He produces incorrect results for Cartman, showing him any slides he deems funny. Despite Cartman's clear vision of all the slides, he says he still has something wrong with his eyes.
- The Eye Doctor apparently has enough skill to take out a person's eyes and replace them with another person's, as he does so Cartman and Kenny, the latter being dead. There is no known real-life medical procedure capable of a transplant of this nature.
