Paysan's eye removal surgery

Hi my name is Amy. Paysan my  9yr old pug is my best friend. He has had a long struggle with medical problems ever since he was a puppy. On most occasion I am able to provide for his medical bills but he has tapped me out of every penny I have. He just recently had 2 surgeries for a urinary problem that his vet is still keeping a watch on. On New Years Eve he developed an ulcer in his eye that is too large and deep that the 2 doctors that saw him could not treat. They both agreed that his eye needs to be removed before the eye ruptures. This is a problem for me since I have already given everything I had for his previous medical conditions. He is being seen by Dr. Kristen Andrews at Stockton Hill Animal Hospital in Kingman, AZ. Please help me help my boy. Thanks for your time.
