To see or not to see

My eyesight. after having cataract surgery there was some problems with my retina with too much fluid behind it. The doctor injected steroids directly into my retina near the eyeball and we waited for the blurry vision to clear up. After both eyes were injected the vision return to 20/20. However, today there was a large white mass above the left eye over the left eye. I called my friend BethAnn and she took me immediately to the doctor's office. The doctor said that the mass was quite normal after having the steroids injected into my eye and that it would be allright
