Hello,
My pre-op said I had 8mm (left) and 8.25mm (right) dilated pupils. These were images taken while using the various machines in the dark.

I have a moderatly weak prescription, with an astigmatism in my right eye. I currently experience halo's in my right eye at night while wearing my contact lenses.

The doctor said due to my large pupils I was at risk for night time problems, even though their laser treated a 9mm area.

I was planning on going to "no touch" PRK at London Place Eye Center in New Westminster, BC, Canada.

They have wavefront technology, which I've seen on various FAQ's may help prevent night time problems, but he never mentioned this during the exam.

How big of a risk am I taking with my ability to drive at night (which I do frequently) by getting laser eye? Will LASIK help over PRK in anyway?

Thanks!

as your doctor said, you are at risk of losing night vision. If driving at night and seeing well at night are important, do you want to still take the risk? Can you tolerate contacts?

I can not tolerate contacts, my eyes go bloodshot for 2 days after wearing them for a few hours. Glasses are simply not good for the sports i'm involved in. I've scheduled my operation for March 1st, 2006. The doctor is going to operate on a 9mm area, with "no touch" PRK (they use a laser to ablate the epithelium instead of scraping it off after putting alcohol on it). I'm fairly confident, after my research, that I'm not in too much risk, and realized after reading some places that I already see halos and starbursts at night, and that there's a 90% chance that they stay the same, or even get better after the operation.

Whats your pescription? You said its fairly low so you may be functional without glasses part time. I also cant tolerate contacts but glasses work fine. For sports perhaps you could use pescription goggles or go bare eyed if you see well enough. If you still want surgury, do one eye at a time. If you arent satisfied after getting the first eye done, leave the other alone.

I got laser eye surgery via PRK 2 months ago (touchless laser version of PRK from london place eye center), and it's been great. My night vision is actually better than it was before. Everything is fantastic! My large pupils have not been a problem. Just thought I'd share, thanks!

thanks for sharing the story! do tell more! You never mentioned your pescription but im willing to bet it was around a -2. Low pescriptions are at less risk for poor night vision. If you were closer to -1, you probably could go without correction much of the time
