Dear HGT 95
Sorry for your disappointment with your medical.
My advice is dated, but I would recommend that you seek specialist advise from an eye surgeon. Many years ago I worked with a surgeon who operated on the eye muscles of "lazy "eyes with a high degree of success. I remember him saying that a lot of middle aged people need treatment due to lack of follow up progress checks from when they were younger.
Hope my advice helps, and good luck.
