Toric IOLIf you are considering a lens implant for after cataract surgery you should become aware of premium lens implants and their advantages over traditional monofocal implants. If you have astigmatism the Toric IOL may be the best option to discuss with your cataract surgeon.

Many patients suffer from this common eye condition known as astigmatism. Often this Astigmatism can lead to blurred or impaired vision if it becomes moderate or severe. The cause of the blurred and impaired vision is the result of the eye's cornea or lens having an irregular shape. A normal eye's cornea and lens have a circular shape whereas an eye with astigmatism has a longer more oval shape.


Astigmatism Definition – Understanding Astigmatism

Astigmatism is a refractive error where people are unable to see objects clearly from a distance or up close. Astigmatism is asymmetric steepening of the cornea or natural lens causes light to be focused unevenly. Astigmatism may occur in varying degrees in each eye and can accompany myopia or hyperopia. To individuals with uncorrected astigmatism, images may look blurry or shadowed. Astigmatism can accompany any form of refractive error and is very common/

Can TORIC IOL implants correct astigmatism after cataract surgery?

Our doctors are pleased to offer Toric IOLs for Astigmatism correction after cataract surgery. The recent advancements in Intraocular Lens (IOL) technology have now made it possible to provide an effective solution for patients that have astigmatism. Until recently, patients that were IOL candidates and had astigmatism, had no option built into the lens, which would correct the astigmatism aspect of their visual condition. Surgeons would typically perform refractive surgery or LASIK after the insertion of an IOL to correct the complete visual picture. If patients did not have astigmatism correction after IOL implantation then contacts or glasses would be required to deal with the astigmatism. With advancements in the optics of IOLs the manufacturers have now been able to accommodate for astigmatism.

Toric IOL technology uses biocompatible materials that have been successfully used in contact lenses and proven safe for the eye. There is an additional cost for this lens implant.

What happens during the TORIC IOL surgery process?

The AcrySof® Toric IOL is surgically inserted into the eye during an outpatient procedure. This process is the same process for cataract surgery and is similar to the placement of many other IOLs. You can get a complete description of the cataract surgery process on this page of our ophthalmology website but we will also provide a short description on this page for your review.

  1. First, the eyes are numbed with medicated eye drops, and the patient is given a mild sedative so that he or she will feel no discomfort during treatment.
  2. Next, a tiny incision is made in the eye, at the side of the cornea. A small probe is inserted through the incision and focused on the crystalline lens, the area behind the cornea where cataracts develop. The probe then emits sound waves causing the degenerated, cloudy crystalline lens to break into tiny pieces, which are then vacuumed away using a specialized instrument.
  3. The AcrySof® Toric lens is then inserted through the same incision in the cornea to replace the crystalline lens and complete the procedure.

* The AcrySof® Toric IOL lens is specially designed to correct astigmatism by changing how light is reflected as it passes through the eye. Using this treatment, patients with astigmatism not only experience relief from cataracts, but are also able to see clearly after treatment without the need for additional vision correction.

In January 2007, Medicare approved a new monofocal IOL called the Acrysof Toric IOL for patients with cataracts and astigmatism.  The AcrySof Toric corrects for both conditions, cataracts and astigmatism. 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 excellent distance vision, independent of eyeglasses and contact lenses.
