To make a long story short, I have been suffering for two years after my cataract surgery. I have visited 11 doctors describing my discomfort of foreign body sensation in left eye after the surgery. All but the 11th doctor told me that there was nothing there and that I shouldn't think about it or that I was too focused on it and that I was imagining it.
I had diagnoses of dry eye, blepharitis and/or meibomian gland dysfunction. None of the treatments for those conditions relieved my discomfort.
Finally, after a year and a half, I happened upon a very knowledgeable doctor who diagnosed corneal nerve damage and conjunctivochalasis. Although the doctors don't admit to this being a direct result of cataract surgery, I never had anything at all wrong with my eyes prior to that.
I had a follow-up surgery four weeks ago to resolve the conjunctivochalasis and am still in the recovery process and hopeful that I can go back to having a normal eye again.
