Had ptosis surgery recently now found out i have mucus on my cornea what does that mean?

Not much: Mucous on the cornea is normal. Just blink and it goes away.

Mucoid plaques : Ptosis surgery initially can elevate eyelids apart so that they don't completely close or stay closed. This results in exposure keratitis or keratopathy. The irritation of the cornea hurts and mucous secretion by the eyeball can adhere to the surface of the cornea (mucoid plaques) ; dead desiccated corneal epithelium can cling on to the cornea creating filaments (filamentary keratitis).
