If you haveÂ astigmatism, you know that it makes it harder for you to get a good prescription for glasses or contacts, and that it interferes with your vision at all distances. It may also interfere with your ability to see clearly after cataract surgery. However, ToricÂ IOLÂ allow us to correct your astigmatism and have clear distance vision or near vision.
AstigmatismÂ is when your cornea is shaped more like a football than a basketball. This shape of lens has not one focal point, but two (or sometimes more), which means that no matter how hard your eye tries, it cannot get a good focus on objects at any distance. To correct this, you can either reshape the cornea with surgery, such as LASIK or a special cornea reshaping procedure, or you can use an additional lens that counteracts the astigmatism.
Toric IOL After Cataract Surgery
AfterÂ cataract surgery, you have many options for the lenses you will receive. You can get a monofocal lens that allows you to see at one distance, or aÂ multifocalÂ orÂ accommodating lensÂ that can let you have a full range of vision after surgery, but unless you get a Toric IOL, your astigmatism will remain. Since astigmatism affects your vision at all distances, it is more likely that you will need glasses all the time after cataract surgery if you do not get a Toric lens.
If, however, you receive a Toric IOLÂ during cataract surgery, you will likely have clear vision without spectacles or contacts for either distance or near vision. For the other type of vision, you can likely select inexpensive vision options, such as off-the-rack reading glasses from your corner pharmacy.
There is as yet no lens that combines Toric vision correction with multifocal or accommodative vision correction available in the US, though the manufacturers of ReSTOR have released such a lens in Europe and are seeking approval for release in the US in 2012.
