Well, I don't like to sound so negative, but if I'd known how it would affect my sight I would not have had the nerve to go through with it.
After living my entire life with extreme myopia (nearsightedness), the surgery completely destroyed my near-sight. With the standard lenses, a focal point must be chosen and my surgeon chose mine to be 12 feet (optimal for driving). And yes, my distance vision, which had always been terrible, is now remarkable. But at a distance of 10" (which was my most acute vision previously) I now have basically white fog. Even with glasses (which I absolutely need to wear at all times, not just for reading) my near-sight isn't what it was and my mid-vision is longer than most; 3 or 4 feet.
Functionally speaking, it's now almost impossible for me to do mundane things like put on mascara or polish my toenails. House work is a total challenge because while I can see the dirt from a distance, when I get within arm's length it's not clear anymore. I work full-time and am on the computer almost all day. It's hard. I've had to get a larger monitor and increase the font size; it's very, very difficult for me to read texts or see properly to dial my cell phone.
Overall, I try to remember that many people have no sight at all - I am very fortunate. But I certainly wish I had known what the possibilities were and what issues to discuss with my surgeon before-hand. They honestly never said one word about my near-sight. Somehow I imagined I'd have all I had before and distance vision too. Please make sure all your questions and concerns are satisfied before you make final decisions. If the multi-focal lenses will allow you to see at all distances I'd say they are worth whatever they cost. Best of luck!
