It is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.
It is a very common procedure and it is generally safe.
When the lens in your eye is clouded, your vision is blurred and it becomes difficult to perform your daily tasks. The doctor then recommends cataract surgery. In the early stages, it is possible to manage and the doctor may tell you to wait till the cataract needs to be operated.
Waiting for the Cataract Surgery will not harm your eyes. So you have time to think about your options. If your vision is still good, you may not need a surgery for many years.
If all the above questions suggests that you are able to do things, then you do not require a Cataract Operation right away.
