Hi. I'm online and happy to answer your question today.
I do not believe that the type of refractive error really helps in one way or another when it comes to lasik.
The most important factors when considering lasik are what your surgeon finds on pre-op exam and testing. There are many issues that come into play when deciding if lasik is right for you and your surgeon, along with yourself, are best qualified to make this determination.
Does this make sense to you?
That is not necessarily true. It depends more on your corneal topography, the axis of your astigmatism and the thickness of your corneal stroma. That being said, all things being equal, you should be in the range that can be treated. Once again, only your surgeon can determine this after pre-op testing.
