GrannyQ, good luck in your surgery. I had horrible fears before mine and found out how silly I was being...wondered why I waited so long to do it. I could see so much better immediately...and I had nothing to fear because it was so quickly done. Do let us know how it goes, we are all thinking about you.
Dr. said it was three years after mine that the film formed behind the artificial lens that caused my sight problems. It happens in twenty per cent of the patients. The twenty twenty is with glasses, and the left eye does't see much at all, but gives me depth precision to see to drive.
