TORIC (Astigmatism-correcting) IOLs
If you are considering a lens implant for your cataract surgery you may want to familiarize yourself with Advanced Technology 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 the common eye condition known as astigmatism. A normal eye’s cornea and lens have a circular shape whereas an eye with astigmatism has a longer more oval shape. Often Astigmatism can lead to blurred or impaired vision if it becomes moderate or severe.
Astigmatism Definition – Understanding Astigmatism
Astigmatism is a refractive error that causes the inability to see objects clearly from a distance or up close. Astigmatism is an asymmetric steepening of the cornea or natural lens and 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 cataract surgeons 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 that 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 are now able to correct astigmatism in one procedure.
Toric IOL technology uses biocompatible materials that have been successfully used in lens implants and proven safe for the eye. There is an additional cost for this lens implant.
Presbyopia and Astigmatism-Correcting Advanced Technology Multifocal/Extended Range Toric
With today’s new Advanced Technology, the Multifocal/ Extended Range of Vision IOL now has the capability of correcting astigmatism as well as distance, middle, and near vision to give the patient the clearest vision.
What Happens During the Surgery Process?
The Toric IOL is surgically inserted into the eye during an outpatient procedure. This process is the same as cataract surgery with a standard, non-prescription IOL and is similar to the placement of many other IOLs.
- First, the eyes are numbed with medicated eye drops, and the patient is given a mild sedative to eliminate discomfort during treatment.
- 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.
- The AcrySof® Toric lens is then inserted through the same incision in the cornea to replace the crystalline lens and complete the procedure.
