You will have to sort this out very carefully.
Opthamologists are MD's who specialize in eye pathology or surgery. but don't always know what lenses are available.
Optometrists are often really good at measuring people for prescriptions and getting all the parameters just right for you.
Opticians are sometimes really clever at finding manufacturers of specialty lenses, and some of them are really good at fitting and adjusting lenses and frames. None of them seems to have it all together. As usual in the medical field you need to study up on your own problems, ask good questions, and make sure all of you professionals talk to each other.

For example, when I had cataract surgery, the Surgeon was excellent, the
refractionist was good, but the optician in the same office did not get the lenses properly centered for me, so they were useless, and had to be remade by another shop.

Good luck
MD
