I was 53 when I had the laser treatment you refer too which was just over 2 years ago. I am delighted with the result, yes, I have to wear 'cheapo' reading glasses in poor light now, but the benefits outway the negatives massively. I have never had dry eyes and stopped using the drops they provided after 24 hours!!
I was reccomended to have the more expensive procedure (just like you), they said this would reduce the very small chance of problems by half, so I decided to pay the exra.
I would reccomend anyone in a similar position to have it done, but maybe this has a lot to do with the fact that I have had no problems to date.
