Depends. Dialysis can change the osmolarity of blood. The osmolarity of the jelly like substance inside the eye and lens can also change. These changes create a flux of fluid out of these tissues. These changes the anatomy of this lens system. So prescription of eye changes. These changes are temporary and not occur each time of dialysis or everyone.
Blurred vision. Epoetin does not cause blurred vision. I would suspect other causes for the blurred vision such as diabetic retinopathy, cataract, dry eye, or other issues. The patient should see an eye doctor as soon as possible.
