Yag caps is a very short laser procedure done to clear cloudy vision that may occur after cataract surgery.
After cataract surgery, some people notice cloudiness (sometimes called after cataract) after several months or years. Sometimes one can develop a thickening of the back surface (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 CAPs.
In case of following symptoms, Yag CAP can be done
Usually, PCO can be treated quite simply using a Yag laser. A doctor can make a hole in the back surface of the 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. Nd Yag caps full form is neodymium-doped yttrium aluminium garnet laser.
Lasers are beams of energy that 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.
The laser procedure is considered very safe. Though there are some risks, serious side effects are very rare.
After this treatment eyesight should be restored to the level the person had following cataract surgery, provided no other problems have developed in the eye.
