Horners Syndrome

Sorry that you and your kitty are dealing with this.

I would request a copy of your kitty's file, including the dental notes that would indicate all meds (including anesthetic) givin before/during and after the dental.....and seek out a Vet Opthalmologist (eye doc). If that's not available, a Vet Specialist. If that's not available, see if you can find a local clinic/hospital that's a 'cat-only' clinic (Vets there often know much more about cats than a multi-animal clinic does.

As for the lack of eating.....feed smelly canned food. Warm it up a little in the microwave (warmed canned food is smellier and more palatable to a cat). I've something found that when dealing with a cat that doesn't want to eat, I dab a little of the canned food on their mouth which prompts them to lick it off....then they're more inclined to eat. It's very important kitty gets food into him. And doesn't get dehydrated. You may have to consider syringe feeding? Try something that most inappetant cats seem to like, like Fancy Feast. Try Tuna juice drizzled over the food. Give treats.

I would, at the very least, get a copy of the file and be seeking a second opinion.

Perhaps kitty had a reaction to the anesthetic? (or dosage of same)......or Vet error? ...though I guess it's likely from the ear cleaning that was done (from what I've read that's a common cause of Horner's).

Here's an article that mentions eye drops that can be given to deal with the 3rd eyelid. Have eye drops been tried?

I would most definitely be seeking another vet's opinion ASAP! There may be more going on other than the eyes, the bloodwork shows he was fine before anesthesia however he is obviously not now. I've seen cats go downhill post surgery when they've had purrfect bloodwork beforehand.
