Declining eyesight

[mek]

So my mother in-law (Thai) is having declining/blurry eyesight. I think maybe cataract. She is a bit hesitant going to see a doctor. I told my wife that I don't mind to help since I know that surgery can be quite expensive. 

Any recommendations on hospitals where in case it is cataract she can have surgery done at a decent price. We are in the Nonthaburi / Bangkok area
