After cataract surgery, some people notice cloudiness (sometimes called aftercataract) after several months or years. Sometimes one can develop a thickening of the back (posterior) of the lens capsule which holds your artificial lens in place. This thickening is called Posterior capsule opacification (PCO). It is a fairly common complication of cataract surgery.
This thickening of the capsule causes vision to become cloudy. It can be removed by Yag laser capsulotomy also called as Yag CAP.
Why it is Done
In case of following symptoms Yag CAP can be done
How does it work?
Usually, PCO can be treated quite simply. Using a Yag laser, a doctor can make a hole in part of the back of lens capsule so that the light can once again pass directly to the retina. For the vast majority of people this can improve vision. This procedure is called Nd:YAG laser capsulotomy. Nd:YAG is the type of laser used for this treatment.
Lasers are beams of energy which can be targeted very accurately. The Nd:YAG laser uses very low energy levels and can delicately cut the lens capsule without any risk of damage to other parts of your eye.
What are the risks of laser treatment?
The laser procedure is considered very safe. Though there are some risks, serious side effects are very rare.
What about eyesight?
After this treatment eyesight should be restored to the level the person had following cataract surgery, provided no other problems have developed in eye.
