Had similar thing happen to me 5 years ago, given no options by AME, so I went to my local Optometrist with the results, who recommended another person at the local Hospital etc. They said they could train the eye with exercises, and be able to sustain the minimums, sounds weird, but it worked. Went back once I could exceed the requirements after about 4 months. Job done. AME was surprised and signed the paperwork.
Also you could probably look at going FAA, as the class one is by far less stringent.
