Had the retinal scan and the lady explained everything and then when the pics were done said it looked OK, but once last years and the year befores pics had been compared wit these they'd let me know. I even got a little slip of paper telling me what to do and which hospital to go to if there was an alergic reaction, which is a new thing, well different from last year. Some one was moaning about it because it was obvious, but it isn't to everyone!
