My prescription going in was -7.5 in my right eye and -6.75 in my left. For those who don't know, that's pretty dang terrible. I could not function beyond walking around my house, without corrective lenses.
Since 7th grade, I almost exclusively wore contacts. My glasses were on my night stand and another pair in my glove box, just for security's sake....
14 days before LASIK, I was told to stop wearing contacts and revert to glasses in order for any corneal deformation induced by my contacts to reverse. This was especially important since I wore "toric" contacts.
On 11/20, Insight LASIK in Boulder performed my surgery. While I am functional without any further corrective lenses, my vision is far from 20/20. I'll be going in tomorrow morning for an exam to determine where I stand, and hopefully schedule the touch up. If I had to venture a guess, I'd say I am no better than 20/30 in my left and north of 20/40 in my right. There is a fairly significant disparity between the two, for the moment.
Nevertheless, I am confident that Insight will make it right. Evidently with prescriptions as strong as mine were, needing a touch up (after a conservative, first pass) is not uncommon.
It makes sense to me that under-correcting is a much safer bet simply because it can be touched up... over correcting cannot. I will report back once i've been touched up and am "as good as I'm going to get".
