I saw this cat, with similar lesions in both eyes but comfortable and visually still, as a “Have a look at this while you are here” freebee examination in a clinic a few days ago. What are you seeing here?
This is lipid deposition with associated blood vessels probably after a corneal ulcer. We’d call this a lipid keratopathy, though I’ve never seen one in a cat before and can’t find a report of it in the literature. Not enough money, or a calm enough cat, to take a blood sample for lipid analysis I’m afraid, but as the cat is happy no treatment is needed. If it were maybe the driver of this truck I passed on the way home from the consultation would be able to help!
