I am working with a team at HCMC in Minneapolis and they sent me to see a neuro opthamologist (Dr. Marian Rubenfeld). I had convergence issues as well and a bunch of other issues (saccades, tracking, nystagmus.... I could go on). So far the prisms are making me more naucseous.... (I hope this is just a temporary adjustment period thing). I am absolutely miserable. Constant dizziness, nausea, and a sense of being off balance for 7.5 months. I guess I was hoping for a miracle with the prisms
