1. What are the reasons to operate on the lens?

There are two primary reasons to consider surgery of the natural lens of the eye:

  1. The lens is opaque/cloudy and it's dysfunctional
    The lens has become opaque and hazy and is not able to focus light well, resulting in impaired vision at all distances.

  2. The lens is still clear but it's dysfunctional
    The lens, while still clear, is unable to change its focus for near vision, and your reading/near vision is impaired; or your lens is mismatched for your eye, resulting in an extreme glasses prescription.

For all of these situations, the surgery involves operating on the lens of the eye and replacing it with a clear man-made lens in order to better focus the light and improve your vision.
