How a Toric IOL Works

When a patient's natural lens must be surgically removed to eliminate a cataract, the toric IOL replaces it and corrects for astigmatism at the same time.

Astigmatism (blurry vision at all distances) is due to an abnormally shaped eye, and the toric IOL corrects for this by refocusing the light entering the eye so that it will focus in one spot on the back of the eye, as it should.
