Some people are "ok" on the quinolones. The FDA has put a stronger warning on them for MGers. Since you need the drops, take each day at a time. If your breathing, swallowing, or generalized symptoms become worse, I'm sure they can find a different drop for you.
The dilation drops contains Atropine, which does the opposite of Mestinon. But your eyes should not be dilated this long. My eyes are dilated longer than most people, but not for days. The eye doctor obviously doesn't realize that "massive amounts" of those dilation drugs are not a good idea in MG! I always ask for less that what other have.
How are you doing now?
All of those eye drops can affect MG. Some people do worse on them than others. If you are still not doing well, you should speak to the prescribing doctor again.
I'm sorry this is affecting you. I hope the surgery went well.
