The ones being discussed are multi focal so I guess they are special made. I have astigmatism in both eyes and need something more than just the standard, they say these correct near, intermediate and far.
Honestly at this point anything is better than looking through frosted windows and using dragon soft.
You might want to try multifocal contact lenses first, just to see if you can tolerate the multifocal aspect of the implanted lens.
I've tried multifocal contacts and they are downright infuriating to me, they claim your brain adjusts. Baloney, you simply get used to less than ideal vision and less than perfect focus at any distance, over time. They are useless while driving at night, The stars are not sharp, light points such as headlights create flare patterns, and
the FAA specifically disallows them for pilots . They currently use concentric lens rings, each with a different focus distance. I believe that most multifocal cataract lenses are made this way too.
If I were to choose, I'd choose a water clear, conventional lens that corrects my distance vision to perfect. Then wear appropriate reading glasses for the near vision I desire. Clarity and sharpness is very important to me. I'm sorry you are having trouble, but it's very likely you will have amazing vision when it's over. What ever you choose, make sure you understand exactly what you are choosing.

The pictures above show how the lens is focused. Could you imagine using a camera lens like this? I will say that some people really like the multifocal lenses, and are thrilled with the results, AND fewer need glasses. Remember, my needs and wants will differ from yours.
