The Visx Laser and is FDA approved for up to 5 diopters of astigmatism

Jennifer J. Lee, MD answers: Correcting astigmatism with Intralase with Lasik?

I am going to be getting the Intralase with wave-guided Lasik with the Visx Star4 laser. The astigmatism is at a cylinder 3.75 and 2.75 in the other my SPH numbers are moderate at 3.25 and 3.50. My glasses prescription has been stable for about 6 years. Should I be concerned that the surgeon will be able to correct the astigmatism?

The amount of astigmatism that you have currently should not be an issue with the VISX laser as it is now FDA approved for up to 5 diopters of astigmatism. Your surgeon will mark your eye carefully and you should be able to have a good refractive result.  With either the intralase laser or PRK the shape of your cornea should not cause an issue.

Most likely they will be doing wavefront measurements and any higher order aberrations will also be fixed during your corrective procedure.
