That's great you're doing well so far! I haven't looked back in the threads, but I'm sure you received well advise here. Being you mentioned blurry vision, Chemo, Cisplatin is one, and other medications can cause various eye problems such as dry eyes, itchy eyes, conjunctivitis, even blindness in some cases like mine, etc. You should let your doctors know of any vision changes just the same as you would with changes in hearing and neuropathy.
