Here's my 2 cents on this subject,I was seen halos when I look at lights and when I looked up to the moon there where one moon in the middle and dozen moons around the center one.Well I went in to eye surgery very worried about the whole situation,to my amazement all went really well.The Doctor did 20 patients that morning,I ask the nurse if they had a production line going on, that made her day.Well the way they do it is they make an incision on the outside corner of your eye.They stick this really fine tube suck out your eye lense and thru the tube they stick a folded man made lense and when it reaches inside it opens up and they stitch it in place.Done in about 7 minutes once they start.I now see really bright again.Ed get it done nothing to worry about.I was given some really dark sun glasses and some drops to put in and I was seen good that same afternoon.
