This kind of sounds like what happened to me. I rocked contacts for almost 20 years, then I developed an astigmatism, and contacts weren't comfortable. I tried many brands specifically made for people with astigmatisms, and they didn't work. I'd have to pour eye drops in my eyes, which I never had to, and eventually I'd just take them out.
The surgery wouldn't work cuz of the slope of my eye or whatever. I'd still need glasses after the surgery.
Ya keretacoonus is a type of astigmatism.
The contacts made for them Don't work for me. So I have to get special ones made. So there is no way to test to make sure they work until the are made. Sucks
