There is really no treatment except surgery.

Although it's unlikely but an implanted IOL can be replaced with a different one if necessary. It is called IOL exchange. Talk to your surgeon to learn how he would handle this situation.

Avoid surgery of both eyes on the same day. Give some gap between surgery of both the eyes. When can I get the second eye operated? It will depend on the vision of the second eye. Second eye surgery can be planned within next 3-5 days.

Once a cataract has been removed, it cannot develop again. However, over time, patients may notice that their vision has once again become hazy. This condition, which can occur with any type of IOL, is known as secondary cataract, or posterior capsular opacification (PCO). Secondary cataracts can be easily treated with a simple laser procedure performed in OPD.

Your doctor will do some tests to measure the curve of the cornea and the size and shape of your eye. Also, doctors may ask you not to eat or drink anything after midnight or in the morning of your surgery.
