Many patients do well with treatment and rehab options and life goes on as always. Some issues are never resolved due to the nature and severity of corneal damage, as in my case, where my prescription keeps changing, but life still goes on and I've learned to manage it. Some patients will never be able to adapt, for a wide variety of reasons.
Don't give up. It sounds as though you're on the right track with treatment, so give it a chance to work.
