Where do you have such abysmal care? I can see any specialist within days. Got my cataracts done this year over a month. First eye scheduled two weeks after diagnosis. Never had a problem or delay scheduling an mri or other scan.
While cataracts are important to you, that surgery is not specialized. It is routine. Specialists, especially at top teaching hospitals/centers, treat life-threatening and often somewhat rare problems. They get the "big problem" cases. And generally, have a good track record treatment.
