It gets rid of the cataracts and, since the natural lenses are replaced with artificial ones, it eliminates what flaws were in the originals. But the artificial lenses are imperfect, too. I did what most people do and chose lenses that gave me good distance vision but require reading glasses for any close work. Objects that are midway between the two are somewhat blurry but not so much that I need to wear glasses to see them. But I can no longer make things clearer by squinting, which is a loss, and I find that in general the replacement lenses provide a less flexible, adaptable kind of vision. As I said earlier, I would rather have my old eyes. I had to wear glasses with very thick lenses, but, with them on, I could see everything clearly. And, without them, I could still hold things really close to my eyes and see.
I do have a pair of prescription trifocals that are supposed to support near, middle, and far distance, but they're a strain to wear because my eyes are constantly having to locate the portion of the lenses that will allow me to see what I'm trying to see. I only wear them when I go out, because I don't enjoy always having to whip out a pair of reading glasses whenever I want to see something up close.
Don't get me wrong: I enjoy not having to wear glasses all the time anymore, and heaven knows the way I see now is miles better than it was with cataracts, but the rigidity, for lack of a better word, of my new vision is irksome. (It doesn't help, of course, that I frequently suffer from double vision because of MS, and it has also scarred the optic nerves in both my eyes.)
Sorry for the tome, everyone.
I can relate to vision problems. The best I can be corrected in far vision is 20/40 and I'm not even that right now in my left eye. As it stands, I can't legally drive at night. All distant vision is a bit blurry. I choose to sit towards the front, if I can. I'm hoping that when I see the opthalmologist next month, he can work on my vision in my left eye a bit more.
