Yes, we had our late dog's eyes done nine, nearly ten years ago. She was 12 at the time and going blind because of diabetes. Some dogs can cope with being blind and do better without the op but our girl had panic attacks so we decide to go for it. One eye was fine, with the other, the capsule of the eye was thin and the stitches tore twice. In the end they repaired with a pedicel (graft) and she had two further happy years. Post op infection is a risk with any procedure sadly.
If it was me I would think seriously about how the dog would manage blind. many dogs (some say most) would find blindness less stressful than the operation and for them, monitoring, with removal of the eye if it becomes necessary might be a better way to go.
Would I have it done again? I think it would depend on the dog. If they seemed happy being blind then probably not. If the dog is so upset by blindness, like our old girl, then yes, i would consider it as for her, the alternative was PTS.
