I absolutely HAVE to work the following day after my upper bleph. Is this going to compromise my healing?

Thank you for your question. I think it's reasonable that you be able to take off a couple days for work from your blepharoplasty. Your surgeon should guide you in this decision. Going back to work one day after your operation may not be prudent.  

I would highly recommend that you do not work the day following your upper eyelid surgery.  It does help to rest a bit and it is helpful to keep ice on and off the area for the first few days.  Overexertion and lack of icing could lead to more swelling or bleeding, which could prolong your healing.  

Each surgeon has his or her guidelines for postoperative care. Allow yourself proper time to heal to avoid complications or prolonged healing. Some surgeons may allow a limited work schedule the next day depending on the scope of the surgery and the type of work. Consult with your surgeons as he or she knows the scope of the surgery and the specifics about you.
