Will crying while healing from an eyelid lift cause damage?

Cry all you want, just don't rub your eyes.  Gently dab the tears with a soft tissue. The greatest threat to a well done blepharoplasty is bleeding and hematoma.  Pre-operatively, avoid blood thinners such as aspirin, Vit E, fish oils, and anticoagulants.  Make sure your blood pressure is under control as the surgery may drive it up and promote bleeding.  Rest after surgery without stress or exercise to avoid bleeding for 10 days to be safe.  

In my opinion, crying will not cause damage but it usually comes with increased blood pressure which causes bruising and swelling.

Thank you for your question. Crying will not effect your outcome, however rubbing your eyes will. Gently dab with a cloth tissue. Hope you feel better. Best of luck, Dr. Heffernan
