Really two questions:
1) I'm 31 years old and have developed mild/moderate astigmatism in my right eye (-1.00). I'm 20/25 for distance vision in that eye, but can definitely see the difference, especially at night. I'm right eye dominant, so the visual picture without my glasses looks kind of hinky to me and can result in eye strain, so I usually wear my glasses at all times. I had PRK when I was 21 with excellent results (5.00 diopters myopia in each eye to plano all around). Will a surgeon do an LRI procedure by itself? Since my astigmatism is relatively mild and I don't have any myopia, I'd like to try the less invasive procedure. My optometrist mentioned the front of my corneas are very flat from the PRK. Will this affect the LRI?
2) I had -0.50 astigmatism as of 2011, and had it go to -1.00 about 5 months ago. Is this considered stable, or should I wait until it's been -1.00 for a full year? I'm in the military, and use NVGs/goggles/gas masks, so I'd really like to ditch the glasses as soon as I can.
