Astigmatism is common and can be classified as regular or irregular astigmatism. Learn the difference between these in this episode of A State of Sight with Isaac Porter, MD.
Most astigmatism is regular where the cornea is curved more in one direction, but irregular astigmatism can also have an effect on vision. This can be more prevalent in patients with irregular corneas from keratoconus, scars, or injuries.
