Typical Astigmatism Results

Postby buddyelf » Thu Jan 14, 2010 8:24 am

Since my vision has stabilized after Lasik, I've been bothered by quite a bit of blurriness due to astigmatism. I have about 0.5 diopters in each eye.

What really concerns me is that my astigmatism is Identical to how it was before treatment. Both the axis and magnitude are the same in both eyes as before treatment.
Could it be that my astigmatism adjustment was written off?

Is this something that could be improved with another treatment?

Need full numbers... if you are -0.5 astigmatic, you could be +0.25 hyperoptic, which in my estimation, makes plano vision. -0.5 astig is not much. Most people overthink their eye adjustment after surgery.

Now, I can see if you are still -0.25 diopter or 'above' with the astig, that things are not as clear as you believe things should be. This surgery is to loosen your dependency from glasses; not to make things completely perfect.

My astigmatism stayed about the same after the Lasik surgery, too. According to the PPR, it actually got worse in my left eye. My subjective refraction for the astigmatism in my right eye went from -0.75 to
-0.50. For the left eye it went from -2.77 to either -2.48 or -2.95 (I had two post-op readings done). As you can see, my astigmatism wasn't corrected much, if at all, leading me to question whether anything was done at all for my astigmatism. The sphere (my near-sightedness) was corrected fairly accurately. The cylinder (astigmatism) was hardly changed. And this had nothing to do with regression because my vision hasn't changed much since the surgery. The problems existed immediately following the surgery and haven't changed.

Which laser did the doctor use on your eyes?

The laser has the ability to correct the amount of astigmatism that you describe. Since it has been several months since your Lasik, you should discuss with your surgeon if enhancement surgery to resolve the residual astigmatism is appropriate.

I assume that your vision clarity improves in brightly lit environments.
