Just a quick note: When you quote your diopters, make sure you note if
they are for glasses, contacts, or your implanted lenses! The diopter
rating appears to change depending on the distance.

For comparison, here's my lenses:
-9.00 and -9.50 contacts
-10.75 and -11.00 glasses
-13.00 and -14.00 visian
-0.50 and 0.00 glasses after visian!

As for the comment about higher diopters having higher risks of
complications, here's what I wrote to another person considering the
surgery:

---------8<---------

I should probably mention, however, that in the initial FDA study there
were no patients with more than -15D. The next block is -10 to -15d,
and the results looked like this (out of 294 patients):

Years 20/20 20/40
1 43.4% 93.7%
2 37.5% 95.0%
3 37.5% 93.8%

I read that to mean, "Not very good odds that people with very high
diopters will keep 20/20 vision. Very good odds that they will keep
20/40 vision." I figured that even in the worst case, I'd STILL be
better off than with my old glasses. Plus, my doctor offered LASIK
touch-ups or whatever was needed to get my eyes closer to perfect.
Generally, the outcomes got worse the stronger your prescription, but no
matter what class, at least 92% kept 20/40. Also, when they say -10 to
-15, I'm not sure which diopter number this actually is. See, I'm in -9
and -9.5 contact lenses, but my IOLs say they are -13 and -14. The
diopters apparently change between contacts, glasses, and IOLs.

The way I figure it, I'm already a good candidate for a retinal
detachment anyway, so no loss there. As for cataracts, I'm totally
gambling, there. My family doesn't have a history of them, so maybe
I'll be okay for quite some time.
