Urgent : Cataract (Unable to see from impacted eye; has been advised to get that eye operated): Suggestion please

Please let me know urgently about it.

One of my family member (female: 74 years old) was suffering from initial stages of cataract in one of her eye.

Yesterday, eye specialist examined, and has suggested her to get operated to avoid the risk of inflammation bursting in her eye leading to loss of eye sight.

She is already not able to see from that eye. She only senses light from that eye.

(1) What would you suggest? Should she get operated or could there be any other way to save the eye at this stage?
(2) What could be a quick home remedy?
(3) Would taking home remedy or herbal remedy at this stage assist (when she is unable to see from that eye)?

Thank you for your time. Tweet
