I recommend returning to your plastic surgeon for advice or seeking out another plastic surgeon or an oculoplastic surgeon for a personal consultation or a second opinion. I cannot be more specific with you with only this photo
Swelling should not be present this long after surgery. It is likely some other problem. See your surgeon or an oculoplastic specialist.
Very hard to tell much from these photos. It looks like you have some fullness of the left, which might be due to muscle or fat. For either of these you might benefit from a revision. What does your surgeon say?
Without an operative report, and an exam it is not possible to explain why your eye is swollen. Did you have any fat grafts? We do not know exactly what was done at your procedure. Follow up with your Plastic Surgeon to compare pre op photos with the final result. A revision may be needed. Best wishes!
