Hi thanks for you message, I have the latest model it is V5c or they call it EVO.
There are several reasons why i did it. It is reversible, the rational for that is that I would have it removed in 10 years and will not to need the reading glasses when I wont do as much sports. It seemed less invasive as it is an additive not permanent solution unlike Lasik.
Maybe I fell for the marketing ploy, I dont know. I do have dry eye in my left eye but the right one is good.
