10 week post op upper and lower blepharoplasty. As you can see, one eye is bigger than the other still. Is this normal? (photo)

Tough to tell from this picture but you may have some ptosis on the left.  This may not resolve, but can be repaired at 6 months.  For the redness:  try some over the counter hydrocortisone cream for one week.  You can also ask you doctor about using a vitamin C serum which can help decrease redness.

To be honest, the photo you have provided is not ideal.  That means that it is very difficult to assess what your issues are.  At 10 weeks after surgery, it is probably that this issue will persist and many need to have revisional surgery.  Generally we advise healing 6 to 12 month before deciding that additional surgery may be needed.  

Needed to post a before photo so we could compare results... Otherwise all that can be recommended is IN PERSON second opinions... 

It's normal to have some asymmetry after blepharoplasty as you are healing.  In your photo, it looks like you have ptosis of your left upper eyelid.  Without examining you in person, it is tough to tell if this is from swelling or a weak muscle.  Your best option would be to wait a full 3-6 months from surgery to see if it heals on its own.  If not, then it is best to see an oculoplastic surgeon.

It will be difficult to provide you with a definitive answer without seeing you in person. However, you are still healing from surgery, and as the swelling improves, your eye asymmetry may improve as well. Follow up with your plastic surgeon to ask about skin care after laser treatment. Everyone has a different post-treatment protocol. Thank you for sharing your question and photo. Best wishes.
