I had cataract surgery 3 years ago. I could get along fine with a daily routine, but the cataracts really showed up when I used a VR headset. After the surgery, my vision improved from requiring glasses for driving to nearly 20/20. Amazing.
If you are old, you may develop cloudiness later. There is a procedure to eliminate that called YAG. I had that about 6 months ago, but I still have a little cloudiness left.
I don't find it convenient to have to use readers. I need 1.25 to see my computer monitor, but 2.5 to read at normal book distance. I have been using Dollar Store readers for that, although I also have two pairs of progressive readers that I got at Walmart for $25, which work well when I am on a phone or tablet. I understand that Medicare will reimburse part of the cost for new glasses, but I'm unsure of the exact amount.
I suggest starting with the cheaper readers, to see if you can get along with single correction or if you prefer something else. When I finally decide to get a new pair of glasses, they will be progressive readers.
