Cataracts and Astigmatism
Cataract patients have a choice of which IOL will work best for them, including the AcrySof® IQ Toric intraocular lens (IOL) which corrects pre-existing astigmatism at the same time that it corrects cataracts.
In one procedure, you have the opportunity to enjoy freedom from glasses or contacts for distance vision – while also seeing life through a new lens. A cataract is like a cloud over the eye’s lens, interfering with vision and making everyday activities, such as driving a car, reading text messages or seeing faces, increasingly difficult. Astigmatism is caused by an irregular curve in the cornea or the lens and makes it difficult to see fine details. Astigmatism can affect vision at all distances and is a separate problem from cataracts. Because cataract surgery is an important decision, you may have some questions. Be sure to address any questions or concerns you have with your doctor before proceeding. This is the best way to get clear answers that apply specifically to your vision and cataract surgery. During cataract surgery, the natural lens is replaced with an artificial intraocular lens. IOLs are generally made of a flexible material, making it easy for your surgeon to insert via a small incision in the cornea. When the IOL replaces the cataract-affected lens, light is able to travel through the lens uninhibited and vision is restored! Cataract patients will generally receive a monofocal IOL, which corrects cataracts but does nothing to correct existing vision problems like astigmatism. If you have astigmatism, you will still experience the blurriness associated with astigmatism after cataract surgery. Unless astigmatism is also corrected, high quality vision will not be gained.
