M, I know a number of people who have had it done (none hunt). Of them, I know one person that sort of regrets it.
I've considered having it done. My concern (right word?) is as follows.
It's been around without splitting hairs for 20-25years. When I think about demographics, I think of 3 age groups
20-30
30-45
45+
So over the past 20 years. While there is lots of empirical data behind it. How much data is there on people who have had it done and are now into their late 60s and 70s. We know what can happen to us and our eyes/eyesight as we age.
People in the first age group are today in their 40s and 50s at the most and aren't old enough yet for that data to be showing and accumulating.
People in the second age group are really just starting to hit their 60s ( 40 plus 20yrs) and the problems that occur as we age. Its my guess this is where the bulk of the existing data exist. (The largest percentiles that have had it done over the past 20yrs).
People in the third age group (likely the smallest percentiles of those who have had it done) are statistics (and it's the "data" I'd want to see) are not adding to the data.
If there's one thing I don't to take many chances on.
It's my eye's and sight.
