This is : A large amount of astigmatism. You should see a corneal specialist to evaluate your corneas for a ectatic disorder like keratoconus.

This indicates: A lot of astigmatism. This much astigmatism should be evaluated for possible corneal problems. Be sure to see a corneal specialist for this evaluation.
