Yeah, it worked pretty well for my purpose. The only downside is that the edges got a bit rounded off, leading to more distortion than ideal in my peripheral vision. It was definitely an improvement overall, in that I was less steroid-aggro while wearing them afterward. My brain had no trouble filtering out the increased distortion, vs. the visual artifacts (starbursting) from the worn out coatings.

I sanded the lenses by hand with 200 grit, then 400 grit, then 800 grit wet sand paper. There was the AR coating, but then under that there was some sort of underlying "toughness" coating that I had to completely sand through to get down to polycarbonate. That's what took the longest, since I didn't really know how far I needed to go with it, and it was fairly resistant to the abrasion. I tried soaking the lenses in isopropyl alcohol to soften the coatings, but I don't think it helped at all vs. just applying elbow grease. Once the surfaces were uniformly smooth but frosty looking, I polished them with Novus plastic polish #3, then #2, then #1. It wasn't perfect like a new lens, but the center was optically clear without any starburst reflections. With all the coatings gone, the polycarbonate quickly picks up little scratches just from cleaning, but it's quick to polish out again.

It was worth it to keep me from going completely insane for the next month it took me to get an eye exam and order new glasses.

Taking corticosteroids briefly then stopping cold turkey like that is pretty rough on your endocrine system. I had to be on the high dose for many weeks to get the desired effect, and my doctor had me slowly taper off over the course of a few months to keep from crashing like that.
