@cherriann and @johnbishop. Thanks for this information. It doesn't sound too awful if everything goes well when he corrects it. I hope tired eyes from too much screen time or this posterior capsulotomy is all this periodic blurriness is. I've been checking the grid chart for macular degeneration, which the ophthalmologist said I'm in the early stages of, regularly; and the lines are still straight. I guess I'd better start learning about that during my allotted screen time. Thanks again and thank goodness for 2 sunny days in western PA. Nancy
