Can They Do Eye Transplants For Dogs?

Glaucoma can be managed medically or surgically.  When medical management fails surgery is the only option.  Enucleation is commonly performed and this can be done by your referring veterinarian.  Other surgical procedures are done by veterinary ophthalmologists.  There is not a true "transplant" procedure meaning taking an eye from another dog and placing it in your dog's socket. 
Surgical procedures for acute (sudden or very recent onset) glaucoma include cyclocryosurgery, laser surgery, filtration procedures, or enucleation.
Surgical procedures for chronic (long term) glaucoma include evisceration with prothesis (the globe is removed leaving the cornea and sclera--then a silicon prothesis is implanted and the globe sutured closed) or enucleation.
Have your veterinarian refer you to a veterinary ophthalmologist for options for you dog.

Yes you can talk to your vet!!! It is costly but it is worth it!!! Good luck!!!!!

There have been so many advances in veterinary medicine, that I'm sure there are vet opthalmologists that do corneal transplants in dogs.  I fear that the cost is prohibitive, but it's worth looking into, no pun intended.
