[Concern] Do I really need surgery for cataracts?

A few days ago, I received a call from my mother, and she said she has cataracts.

Then, he says he needs to undergo surgery and is very worried.

First, I reassured them that cataracts are a common condition that develops with age and that surgery is not difficult, but I am worried because of their advanced age.

My mother is currently 82 years old, and I want to know if surgery is the only best option for her cataracts.

Is there no other way?

I'm also curious about practical tips to delay cataract surgery.
