Cataract Surgery - More Info, please

At first my cataract surgery seemed to have gone perfectly. Now I am not so sure. I return to the eye surgeon on Tuesday. In the meanwhile, if you had any after effects, beyond headaches, would you tell me what they were and how long the lasted?

My eye does not hurt. It does not appear to be infected or inflamed. But it does seem to be doing at least one strange visual thing - every now and then it appears as though a bubble is under the lens at the edge. It started when I was in the bed and I thought there was an insect on my pillow. I don't feel anything. I just see it. Has this happened to anyone else? Did it go away?
