Correcting Astigmatism after Cataract Surgery with Toric Intraocular Lens Implants (Toric IOL’s)
When the actual human lens of the eye becomes cloudy it is called a cataract. Since we are removing the focusing lens of the eye we must replace the natural lens with an artificial intraocular lens implant in order to help the eye focus better without having to wear big thick glasses like most of our grandparents had to do many years ago. While replacing the eye with an clear IOL can correct for the cloudiness of the original cloudy lens, until recently we did not have the capability of correcting for astigmatism which may exist. Toric IOL which are specially designed to correct for astigmatism along with overall distance vision following cataract surgery can now be used to try and reduce the amount of astigmatism post operatively improving the patients vision without glasses. The patient may still need to wear glasses for distance and near for precise vision, but with toric IOL’s we have the opportunity to improve even further the patients uncorrected post op vision.
Before Toric IOL’s people with astigmatism post operatively would have the option of wearing glasses which would correct their vision or undergoing corneal refractive surgery after their lenses were implanted. The advanced Toric IOL’s today can help correct the imbalance caused by an irregular cylindrical corneal shape in patients called astigmatism. There are several different types of FDA approved Toric IOL’s including AcrySoft Toric Lenses for example.
The risk of a Toric IOL includes poor vision as a result of the lens rotating out of position, although this risk exists with any type of intraocular lens implant. Toric IOLs are considered safe for most patients when indicated to correct astigmatism and are a viable option to correct vision problems associated with both cataracts and astigmatism. Talk to Dr. Shettle to learn more about these lens option and find out if you are a candidate to have this type of intraocular lens implant when you require cataract surgery.
