Found the piece of paper my vision Rx is written on:

OD (right eye): -400+200X113
OS (left eye): -375+250X070

Okay. So near as I can tell: in my right my nearsightedness is four diopters, and my hyperopic astigmatism is two diopters, at 113 degrees. In my left eye, my nearsightedness is 3.75 diopters and my hyperopic astigmatism is 2.5 diopters, at 70 degrees.

Apparently if my astigmatism is worse than two diopters, the correction I'm going to get with surgery is rather unlikely to be perfect.

This doesn't explain why my right eye is the one that sees worse with my contacts. Also, the base curvature of my corneas is 7.5. Which is, according to the eye people at work, pretty damn curvy. Hence the problems I had with soft torics.

Blargh.

Heh. Now I'm curious what everyone else's Rxs are. Post'em if you got'em.

I just looked up the definition for "hyperopic," and I think I must be reading the Rx wrong. In hyperopic astigmatism, if I'm looking at a grid/tic-tac-toe board, etc; the horizontal ones would be clearer. But I see the vertical ones more clearly. WTF?

My Rx is -16 in one eye and -16.5 in the other. Which is very, very, very myopic. I am not sure on the rest of it, though. I'm only slightly astigmatic, so I never paid much attention.

Wow, that's pretty bad. The site I'm looking at says that past 10 diopters, you won't even get in shooting range of 20/20 with laser surgery.

It's frustrating. My glasses give me 20/15, but my contacts give me around 20/25 or 20/30. I get so frustrated trying to read things, whether close up or far away, with my contacts on. You can legally drive with that vision and no correction, but how do those people read any road signs!?
