30 days post op upper blepharoplasty- incisional dehiscence? (Photo)

Generally the best thing is to put an antibiotic ointment on the raw skin.  If it seems to be getting worse (swelling, redness, tenderness-signs of infection) or you have bleeding, arrange to be seen by the surgeon covering call for your surgeon or go to an emergency room.  I suspect the need to actually do that is small but listen you your own concerns and take action if you feel it is necessary.

Thank you for the question. The wound will heal with time with antibiotic ointment. It is vital to contact your board certified plastic surgeon. Good luck.

At this point you may want to keep it clean and apply a thin layer of antibiotic ointment (the same one that was probably prescribed to you after surgery). This incision will likely heel on its own. You can see your cosmetic surgeon next week for evaluation. The hard nodule at the distal end is most likely scar tissue that should settle with time and gentle massage. 

The pictures you've posted are not alarming. Just keep the incision moist and well protected with large sunglasses. Avoid stressing the incision and contact your surgeon on Monday. There is no emergency here. This will likely heal just fine and if necessary, Your surgeon may revise the scar in the future or treat a hypertrophic, hyper pigmented or widened scar with LASER resurfacing. The hard nodules at the end of the incision are expected scar tissue which will begin to organize and contract at 3-6 weeks post-trauma.

This isn't very common, but the eyelid wounds can be susceptible to coming apart up to a few weeks after surgery.  I always warn my patients to not rub, pick at the wounds after the sutures are out for a few weeks to avoid dehiscence.  The hard nodule at the outside corner is not uncommon and will usually flatten and soften over weeks to a few months.  I don't know how you sleep, but if you are a face/stomach sleeper you may need to start wearing a mask at night to help protect your healing eyelids.  As far as what to do now, you can keep antibiotic ointment on the incision and follow up with your surgeon when back in town.  Some small areas will heal fine without further intervention, but some restoring and cleaning up of the wound edges may be needed for the best result.  If you get increasing redness, pus, or pain then I would get oral antibiotics prescribed.  Try to avoid getting the wound wet and keep the area clean.  Best regards.
