An Intraocular Lens (IOL) is a synthetic lens used to replace a patient's natural lens during cataract surgery. Up until now, IOLs could typically only correct farsightedness or nearsightedness, but not astigmatism.
In fact, patients with astigmatism in the past had to continue to wear correct glasses or contacts after their IOL surgery, or investigate the possibilities of laser vision correction, such as LASIK, Custom LASIK or PRK. One other option eye surgeons have tried in the past decade was making an incision in the cornea to correct astigmatism.
But now, thanks to the advanced technology of premium IOLs there is a new option. With Toric IOLs astigmatism can be corrected with a lens exchange, as well.
That's good news for the estimated 20 to 30 percent of all U.S. cataract patients who also have a large degree of astigmatism.
Astigmatism results in blurred and distorted vision, caused by an irregularly shaped cornea. A normal patient's cornea is round, while a patient with astigmatism has a cornea that is oval-shaped. Toric IOLs are specifically designed to correct the vision imbalance caused by that oblong-shaped cornea.
Toric IOLs are:
- Soft, foldable lenses that are easily inserted and implanted in the eye.
- Made of safe, non-toxic materials (silicone or acrylic).
- Proven effective.
- Removable (if necessary).
- Often the best solution for complete vision improvement for patients with both cataracts and astigmatism.
There are two kinds of Toric IOLs:
- The STAAR® Toric IOL™ The world's first Toric IOL, the STAAR lens has been FDA-approved for more than 10 years.
- The AcrySof® Toric IOL™ Manufactured by Alcon®, this Toric IOL has been approved by the FDA since September 2005.
Is a Toric IOL right for you?
To determine if a Toric IOL is the right option for you, our highly skilled cataract surgeons and staff will perform tests, before your cataract surgery, to see if you have moderate or high astigmatism. If you do, a Toric IOL may be appropriate.
If you have astigmatism and are also facing cataract surgery, please contact the knowledgeable Toric IOL staff at Oklahoma City, Oklahoma based Hummel Eye Associates. We can give you the facts you need and present all of your options.
