Does a blehparoplasty help people with grave's disease?

Depends. Usually orbital surgery for severe proptosis / lid retraction first, then extraocular muscle surgery for alignment issues, and lastly lid surgery, so it may help, but have to be careful about dry eye.
Generally no. Grave's disease causes the contents of the orbit to expand and push the eyes forward and out. There are several stages of surgical procedures which can help reposition the eyes, but none of these correct the grave's disease itself. A blepharoplasty may be indicated after the grave's is controlled and eyes repositioned, but the risks are much higher and generally are not necessary.
Depends on severity. Depending on the amount of lid puffiness, and presence or absence of lid retraction, the eyelid position and the excess fat and skin can be corrected to improve the appearence. Many people after the acute phase of the disease , are left with eyelid problems that can be fixed with different types of eyelid surgery.
Not usually. Graves disease may make the eyes more prominent due to swelling and fullness of the tissues inside the eye socket. This may in fact make blepharoplasty surgery more risky for patients with grave's disease. And should be done with caution.
YES. Yes, but it is not a traditional therapy. It may involve removal or repositioning of the fat in addition to movement of bones (orbit) around the eyeball (globe).
No. It risks more exposure of the globe and is contraindicated. Other more involved operations can be of benefit.
Surgery can help . Graves disease, creates several effect on eyes; retracts the eyelids and can push the eyeball forward. Eyelid surgery can reduce retraction and raise the lower lid giving a more vatural look to eyes.
Surgery can help . The surgery to treat the eye problems (prominant eyes) associated with grave's disease typically is a different procedure than than a cosmetic blepharoplasty.This may involve work on the bones around the eyes.
