Lasik safe for smaller/bigger pupils?
Question:
They did lots of measurements and then said one test was a bit off, and is sometimes just caused by dryness. So they said to put in eyedrops 6 times a day and come back in 2 weeks. which I did. they redid the test and said it was ok and safe to proceed.
while they didn't say anything specific to me, I overheard them talking about pupil size and how mine were just on the verge of being either too small or too big; but I can't remember which one.
but the said it was fine and want to do the surgery. but I am scared that they just want my money and while they seem nice, you never know and this is obviously a life changing event.
I looked online and saw that (i think) bigger pupils can cause problems. does anyone know if this is a major issue that I need to worry about? tks!
Big Pupils can cause an issue, especially for your vision in the dark. They use the laser on a certain diameter of your cornea, not the whole cornea, so if you have big pupils you they can dilate bigger than the correction zone in the dark. That would cause major night driving issues and other things to do with glare at night. If they did not make you feel comfortable with it, then ask questions until you are comfortable. They are one of the biggest, but not always the best. You should Read the online book by DR. Rober Maloney from the Maloney Institute. Here is his web links
The difficulty with your question, "Does pupil size matter with Lasik," is that the answer can be yes, no, and maybe.
I work for a nonprofit Lasik patient advocacy. We don’t provide Lasik, just Lasik information and we certify Lasik doctors based upon patient outcomes.
The excimer laser that reshapes the cornea during Lasik fully corrects a limited area. The size of this optical treatment zone is commonly between 6.0mm and 6.5mm, depending upon the laser and treatment required. The lasers can treat larger areas, up to 11.00mm on some, but everything outside the optical treatment zone will be undercorrected.
If your naturally dilated pupils expand beyond the optical treatment zone, then fully corrected vision from the center mixes with undercorrected vision from the outer edge. This often presents as halos or starbursts emitting from light sources at night. These halos can range from a minor nuisance to debilitation and you cannot drive.
Although this sounds like a simple formula, it is not quite so simple. Many studies have affirmed that not everyone who has an optical treatment zone smaller than their naturally dilated pupils has night vision problems. It appears that if the correction is small, the probability of night vision problems after Lasik is less, even if the optical treatment zone is relatively small.
Other issues become important too, such as the curvature of your cornea (flatter corneas are more problematic), if you have astigmatism, and even the dry eye problem you discussed.
It sounds like you are very myopic (nearsighted, shortsighted) and have at least moderately large pupils. I highly recommend you read our full article about Lasik and pupil size and discuss this in detail with your surgeon.

Not sure… you should contact another doctor for a second opinion, and maybe even a third if you want to be really safe. Tthere is a really good San Diego Lasik website that has lots of info and some very informative Lasik articles. See the links below:

I think it is same for both. But before you go for lasik try to do some consultation with your optometrist and see if you are eligible for one. Also you can consult free online about lasik.

Pupil size can be a problem, it really is a case by case issue. The only way to really determine is to get a complete evaluation and thorough exam. The second part is where the test your eye and make sure it is safe and ready for the procedure much more thoroughly. TLC is an ok place, however they only give the pre-evaluation/consultation, not the thorough exam.
I had a friend who went to Lasik Plus and they also offered the free evaluation, but also a free thorough exam. It did take a little while to do (about 90 min) however he was able to be confident he was able to get the procedure afterwards and had great success with it.
You can find a location near you and schedule an exam at:

Schedule a free exam, worst that can happen is they will tell you aren't able to get the procedure, and you won't even have to pay for the exam (most other places charge for the thorough part of the exam)
Hope this helps you!
