Cataracts Treatment

I am having constantly headache (portion between the eyes, not the sides of my head) my eyes are tired and sleepy, I wanted to close my eyes always, even how many hours of good night sleep, I still feel tired & headache. I consulted several ophthalmologists, the result is immature cataracts. after applying the prescription given to me for a new set of eye glasses & medicines, like Chloramphenicol + Sulfacetamide (Spersacet -C) eye drops & Dextran 70 (Tears Naturale) eye drops. The pain is still there. Can someone help? Thanks if you can.

So my dog got cataracts and so I spent $3,000 for him to have the surgery.
First off the 3k was for both eyes, it would have only been $1,500 for one eye, but both had the cataracts. THE point is, the doc said…oh well the lense was too thin for the one eye, so we couldnt fix it.
So now my dog can only see out of 1 eye, and runs into walls and things.
Then we go for our “follow up” visits which are $120 dollars for the visit and $130 for 4 bottles of eye drops that he needs.
So every month that is $250 dollars! Come on doc, you are killin me here.
Do I have the right to ask him for a price break or for a $1,500 refund of the one eye since he didnt fix that one? Or what should I do?

I have my right eye operated but wants the left eye to be slow down in cataract build-up.
