Eye Care After Cataract Surgery Do You Agree With What I Am Thinking?

Do you agree with what I am thinking? - eye care after cataract surgery

The ophthalmalogist operated'm dumping my father.
My father had surgery for cataracts. After surgery, the doctor suggested my father to eat, fish oil, omega-3, etc. for the health of the eyes.

However, this doctor has never suggested to my father, eating, vitamins, years before cataract surgery.

Does not make sense to people for their health as soon as possible and to look after the surgery? Meaning, so my dad would have the doctor about vitamins, long said before the operation.

Do you agree?
