Lower transconjunctival bleph, w/ fat grafting 15 weeks ago, why is my left eye still so swollen and asymmetrical? (photos)

Has been nearly four months since surgery and left eye remains persistently swollen even after dilute steroid injection of kenalog 10 at 12 weeks post op. Appears as though fat took too much on left side and not enough on right side. Swelling or fat under left lower lashline is pushing up lower lid and blocking significant portion of iris. Right eye looks same as pre-op photos. Can anything be done to resolve this? When should I consider revision? Scared at thought of this being permanent!
