If the Acanthamoeba has been in your friends eye for 2 years then
there would most probably be quite amount of damage.  Which seems to
be the case as she can not see through it properly.  Is the
Acanthamoeba still present or has the treatment been successful?  If
there is still Acanthamoeba present then she is probably being
reinfected.  A good source of Acanthamoeba is contact lenses, if she
wears them and still has organisms in her eye then she should dispose
of the cleaning/storage solutions, lenses and washing/storage
containers and get new ones.  Another part of this is if she is using
the correct cleaning/storage solutions, because if homemade
alternatives are used instead of the commercially produced ones then
it is not surprising that this infection has occurred.

I do not know much about relieving the pain of the eye, or the cause
of it.  Sorry but I can not give much help with this part.
