Upper eyelid Surgery and under active thyroid - Will this be a contraindication for surgery?

You potential eyelid surgeon should be able to throughly examine your eye. Do not go to some idiot who performed eyelid surgery without the ability to examine and diagnosis eye surface issues. Eyelid surgery causes dry eye. Do you have dry eye? If your potential surgeon does not even have the skill, experience, and equipment to personally assess this, how will they manage these issues after surgery? Having a surgeon who relies on another doctor to examine your eyes is a formula for unhappiness.
