Curious about cataract surgery

Does cataract develop in everyone as they age?

So, after cataract surgery, is there no longer a risk of recurrence?

Some people say that cataract surgery is simple, is that really true?

How much does it cost?

If cataract surgery is simple, can I go to any ophthalmology clinic to have it done? Or should I go to a large hospital that specializes in it... My mother is currently showing some symptoms like that, so I am curious.
