Hi Christine. My female Blossom had cherry eye surgery in bothneyes last year when she was 7 months old, we did it at the same time as her spay surgery. We also opted to have the gland tacked back in. She is now 2 and 1/2 years old, and her eyes are beautiful, you would never know she had surgery on her eyes. Our vet did a very good job. She didn't have any swelling after her surgery, and we just had to put antibiotic drops in her eyes for a week after her surgery, and we had a follow up a week after, for a check up and her eyes healed very quickly. I don't think it should be swollen anymore especially 2 months after her surgery. This is not normal, it should have healed by now. Have you considered getting a second opinion? Maybe she also has Entropian of her eye, and this could be causing irritation of her eye? I would definitely take her back to the vet and have her check it again, and if you aren't happy with the answers the vet gives you, you could take her to an eye specialist to see what they say. I hope everything works out and her eye heals soon. Please keep us posted on what the vet says.
Here is a picture of Blossoms eye before and after surgery.
