Could I get upper eyelid surgery if I have Ehlers Danlos syndrome?

Yes eyelid surgery should be possible even if Ehlers Danlos syndrome present but important to see an oculoplastic surgeon for evaluation and treatment.

You ask an interesting question. You don't specify what kind of eyelid surgery you are considering. Every patient is different. There is no one correct answer for every patient. Your case requires that you have an in person visit and consultation with a fellowship trained Oculoplastic surgeon. You really need to have a physical examination of your eyelids and discuss your options. There are many qualified surgeons in your area.
