In traditional cataract surgery, the surgeon implants a monofocal artificial lens, commonly called an "intraocular lens" (IOL). If you have astigmatism, however, you may still experience blurred and distorted vision because a standard IOL cannot correct corneal astigmatism. In January 2007, Medicare approved a new monofocal IOL called the Acrysof Toric IOL for patients with cataracts and astigmatism. The AcrySof Toric IOL corrects for both conditions (cataracts and astigmatism) simultaneously.
The Acrysof Toric IOL is a foldable, single piece lens that is implanted during cataract surgery to replace the clouded lens. The unique design of the AcrySof Toric IOL makes it possible to reduce or eliminate corneal astigmatism and significantly improve uncorrected distance vision. AcrySof Toric lens provides QUALITY distance vision, independent of eyeglasses and contact lenses.
Since the Acrysof Toric IOL is a monofocal lens, it will still be necessary for patients to use reading glasses for fine print. However distance vision will be greatly improved especially since a patient's astigmatism will also be corrected.
