Thanks for your reply. It may be the prednisone, but I think it goes back to having PMR. My doctor sent me to the ER because of the pain I was having. I saw an ophthalmologist the next morning. She said I was ripping layers off my cornea every time it happened, I really thought the cornea specialist would be helpful, but she didn't have a clue what was wrong. I will just keep using my ointment and eye drops. I think I have tried every drop out there. lol
