There is at least a one in three chance that you have enough astigmatism to benefit from treatment during cataract surgery.  This can cost several thousand dollars.  


For some, astigmatism management is important to achieving an excellent outcome.  For others, it is not necessary.  Which person are you?  This website will show you where astigmatism comes from and how to estimate your anticipated postoperative astigmatism.  It will show you with simulators the approximate effect of your astigmatism on your vision.  You will learn how astigmatism is treated during cataract surgery.  If you like to dig a little deeper, you will learn about the optics of astigmatism and how this applies to the eye.

You will be directed to the subscription portion of our site.
