    Someone told me to get soft lenses to replace the natural lens when my
    cataract is removed. I have searched the net and found no information
    on this.

    Are there two types of lenses? What are the advantes/disadvatages of
    each? Are there different qualities of lenses being used? Are the
    differences in quality of lenses used in Ontario, Canada significant?

  2. I believe you are referring to foldable vs. rigid implant lenses.

    Foldables are usually made of silicone or soft acrylic, and can be folded or
    placed in a tubular injector and can go through a small (ie <3mm) incision.

    Rigid lenses, the only kind used up to maybe 10 years ago, and still
    occasionally used, are polymethylmethacrylate plastic, and go through a 4.5
    to 7mm incision.

    Optically they are about equivalent. The advantage of the foldable is the
    smaller incision size.
