To overcome the problem of cataract, surgery should be performed. Especially if these symptoms are very disturbing. If not interfere, usually wait until the cataract becomes mature. In cataract surgery, the lens with the lens removed and implanted IOL (Intraocular lens) are included in the lens capsule.

This method is rarely used because the resulting wound is large enough.
The lens is removed by using laser. Injuries tend to be less than if you use a knife.
With this technique, the lens is not removed intact, but destroyed first. Emulsification or destruction done using the phaco machine. This ultrasound energy machine will produce 40000 vibrations / second to destroy the lens. After the lens is destroyed, then the lens is removed and installed intra ocular lens. If using a foldable lens, injuries caused very small, about 3 mm because the lens can be folded so as to enter into the eye do not need a large incision.
The lens implant is made of PMA. The lenses are different from the original lens implanted. IOL lens can not adjust the sight distance is much closer, in contrast to the original lens that are elastic.
