Expert Solution

Step 1: Define Cataracts

Cataracts:

These are the eye conditions which are common where the natural lens of the eye becomes clouded over time.
This clouding leads to blurred vision and decreased eyesight.
This clouding results from the accumulation of damaged proteins and the natural aging process.
Genetics, injury, or certain medical conditions may all be the factors that cause cataracts.
The only effective treatment for this cataract is surgical removal of the cloudy lens and replacement with an artificial one, because the lens lacks efficient repair mechanisms.
This surgery is a routine procedure with a high success rate, which restores clear vision and improves the quality of life for millions of people all over the world.
