As you know a cateract is when part of the lens goes cloudy. Cateract
surgery involves cutting this cloudy bit of lens out and putting a plastic
bung (lens) in the hole. The cateract has to be big enough for a plastic
bung to be fitted which is why there is often many months from 1st
detecting a cateract until it is big enough to work on.
Some people will find that sometime after an operation the plastic capsule
that holds the lens will thicken, making the image fuzzy again. This
thickening can be zapped with a laser to thin it down. Thus restoring the
clarity.
This is different to laser treatment for age related long sightedness. This
is when the lens has lost its elasticity due to age. As a result the
muscles cannot stretch and squash the lens thus making focusing hard. In
this case, the laser is used to cut notches in the lens allowing it to be
stretched and squeezed again. So you dont have to wear glasses anymore.
