What's that squiggly line in my cat's eye? Is it a worm? Vet cost?

I think my cat might have Thelazia callipaeda. I noticed a glint in his eye that seemed odd like something was stuck. When I got closer it looks like a clear squiggly line which matches online pictures of that. Do I go to a vet? How much would something like that cost to fix? I'm so worried about my cat :(. The picture is not my cat but looked very much like that

This definitely can be Thelazia. This worm invades the conjunctiva and can be found near the eye like this. It's difficult to tell depth from the picture, but it's also possible that this is a worm inside the eye, which can be due to heartworm, or other round worms. In both cases you'll need to go to the vet for removal. It's not an emergency, but good to get an appointment within the next day or two. If it is in-fact Thelazia, then removal is not complicated when done by an experienced veterinarian. If the worm is inside the eye, then removal is much more complicated and you would have to be referred to a veterinary ophthalmologist for this. I hope that helps and your kitty gets better soon.
