i am familiar w/using your blood for the eye issues as my optometrist suggested that; it sounds like you have/had something different in terms of how dry your eyes are...mine now gush and water and i've tried all eye drops; think a few mo. ago i had temporary eye plugs put in but with the post covid brain fog, i can't remember if they helped or not. i see the optometrist next week. many many yrs. ago i had bleph surgery which i believe was the main reason why i have dry eyes as eyelids don't close completely while sleeping but i think the virus has definitely affected my eyes as well as so many other body parts. so happy you're getting relief finally.
