Astigmatism Correcting Lenses

Astigmatism is an imperfection in the curvature of the cornea that causes a distortion of light rays entering the eye. Patients with astigmatism generally require prescription glasses or contact lenses in order to see clearly. Cataract patients with higher levels of astigmatism who receive the standard intraocular lenses generally need glasses both for distance and near vision after surgery. A revolutionary new advancement in intraocular lens optical technology is now available that corrects astigmatism at the time of cataract surgery and reduces the need for glasses post-operatively.

Both Drs. Colvard and Kandavel have extensive experience with Toric IOLs, having participated in the original FDA clinical studies which lead to the FDA approval of the Abbott Medical Optics Toric lens. The Toric IOL redirects light rays distorted by corneal irregularities and brings them into sharper focus on the retina. Although patients who receive the Toric lens generally still need glasses for reading, Drs. Colvard and Kandavel are now able to reduce the need for distance glasses for over 90% of patients with cataracts and astigmatism with this single, precise surgical solution.
