Astigmatism is a common refractive eye condition that that is most often due to an uneven curvature of the cornea. If the cornea were perfectly shaped, it would have a spherical round even shape, like a basketball. In eyes that have astigmatism, the cornea is typically curved more like an oblong, football-like shape, similar to the shape of the back of a teaspoon. “Depending on the degree and orientation of the unequal curvatures, astigmatism can cause mild or even severe blurry vision,” explained Dr. Cassidy.
Patients with cataracts and who are in need of cataract surgery have three choices when considering how to correct their astigmatism. First, patients can simply choose to be dependent on wearing eyeglasses after cataract surgery in order to correct astigmatism. Second, if appropriate, some patients may opt to have an additional surgical procedure called Limbal Relaxing Incisions (LRI) or third, patients can elect have an astigmatism correcting toric lens implant in which the astigmatism correction is incorporated into the lens prescription just as in eyeglasses. “Toric lens implants are placed in the eye in exactly the same manner as ordinary lens implants at the time of cataract surgery and correct the astigmatism as part of the cataract surgery operation,” further explained Dr. Cassidy.
