Well long term
steroids is not good. Durezol is pretty strong. 5 months on
steroids is a long long time. You could try weaker steroid like lotemax, you could discuss topical Restasis or Xiidra. You could try lipoflow treatment for your MGD, you could try MG probe and express. You could see a rheumatologist to see if you have any underlying auto-immune disease that might cause severe dry eyes and slow healing such as Sjorgren's Syndrome, rheumatoid arthritis, sarcoid, etc.
