Steroid shots for ectopion and lower lid retraction. Any suggestions?

The answer depends on exactly your eyelid problem, it extent, anatomy, etc. Steroid shots do take time to work but they only so much. See an oculoplastic specialist for experience in revision eyelid surgery.

The steroid is not going to magically undo the changes from your surgery that you showed in your post operative photographs.  It will help quite the tissue and soften the appearance.  Essentially it helps speed things up but it does not transform the factors that lead to the eyelid position which are related to a motor nerve injury to the lower eyelid.  That combined with structural issues present in the eyelid lead to this unsatisfactory outcome.  It is improbable that the eyelid will resolve to a point where you will be satisfied with the cosmetic and functional outcome.  Time is needed to heal until you are ready for the reconstruction you need.  You will need to hunker down and let your body heal.  This is very frustrating and the last thing you expected following a cosmetic eyelid surgery.  

Sorry to hear of your complication. It sounds like everything you are doing so far is correct. You should not have another steroid injection. You might need surgical correction of the ectropion, but this will likely be easy for your Oculoplastic Surgeon to repair. Good luck,
