I am not a doctor but I will tell you that I had my throid removed a year ago (
graves disease)
and I still have lid retraction. If TSI nad Trab antibodies are normal,
and your daughter has still bulging eyes, then thyroid surgery cannot offer a lot. If there are these specific antibodies, then yes. Maybe surgery is a sollution.
In general, It may take three years for the eyes to go back, even if you are eythyroid.
