[Question] Precautions during cataract surgery

My mother has already been suffering for about five years now.
I had cataracts.
The hospital suggested trying to stop the progression with medication first.
I have been administering eye drops so far.

Recently, one eye has been appearing very blurry.
They say it's uncomfortable.

There are no other symptoms, just blurry vision.
They say it feels a bit itchy.

I think it's time for the surgery.
There’s no one around who has had surgery, so I have no one to ask...

Precautions to be taken during cataract surgery
I would like to know if there are any important things I should be aware of.
