Paraphrasing joemike, I've got my eyes crossed for you!
Since you said earlier that dexamethasone is 6.5 times as strong as prednisolone acetate I've been curious about why your surgeon defaulted to such a strong drug, and following your story, I've suspected for a while that your problem could be steroid overdose.
I hope you've nailed it!
Interesting that everybody I know or have run across that has had cataract surgery has had both eyes done in quick succession, while my surgeries were six years apart.
