My wife had cataracts and was referred to a specialist. The concern was the eye drainage would plug. They did not tell us that it probably would be operation but insisted that she needed to replace her glasses. We trusted them and spent 5 or 600 for new glasses. That was in June and in August she had he cataracts done and we now had a pair of glasses we did not need any more. Thanks a lot. I have no plans in going back to them. What a waste.
