Sugar had cataract surgery in January. She is 10 year old bichon, so it is a bit different; age related cataract vs. juvenile & dog vs. cat. But I am SO glad we did this. She can SEE! Well worth it. We only did one eye for now, on the surgeon's recommendation. One eye was completely blind with the cataract. The other has about 30% peripheral vision. So the surgeon recommended doing the blind eye, that way if anything went wrong, the dog still had the limited vision.

For funding, you can try www.imom.org.
For payment plans, you can try www.carecredit.com

Also, check with your state veterinary association. The RI vet group does have a grant program.

Is there a vet nuniversity program near you? They may have a funding option; however, that may require that you use their facilities and docters; it sounds as though you have found an excellent surgeon already. maybe his office also has some suggestions for funding options.
