They are floaters and 99% of people over 60 have them. They come and go, one of life’s things.
I haven’t had lazer, but have had new lenses, it’s done by numbing ones eye, they then cut into the white bit go inside and somehow dissolve the lens at the back of the iris. They then put a man or woman made lens in its place. Apparently it’s made of the same material as fighter jet canopies. The operation awake mind, takes about 10 minutes. I can now see like an eagle. Thing is my girlfriend and others says at certain angles and light they can see my purples shining silvery. Just right for Halloween “eh” I have very dark brown almost black irises.
