Cataract surgery is the kind of surgery that most people after a certain age would require because the forming of cataracts is something that is quite a normal process.
Cataracts occur when the natural lens that every human being possesses inside their eye becomes cloudy and unclear.
So of course if this lens becomes unclear to view through, it would also distort vision. This is the problem that a cataract surgery would fix, something that many people over time develop. Although cataracts are developed over a long period of time and they are most usually experienced by people of an older age, there are chances of them developing in a more rapid pace as well.
