Astigmatism is a condition that occurs when the cornea has an oval shape instead of a spherical shape, and causes blurry vision at all distances. Toric IOLs are designed to compensate for this while simultaneously correcting near and distance vision in the same way as glasses or contact lenses. These IOLs are known as "Premium Lenses" because of this double correction.
A toric lens can be implanted during cataract surgery to correct a patient’s astigmatism, thereby eliminating or reducing the need for glasses following cataract surgery. While cataract surgery can improve distance vision, a Toric lens is an excellent solution to correct astigmatism during the same procedure, further reducing the need for eyewear following cataract surgery.
Toric IOL Options
The FDA approved the AcrySof IQ Toric IOL (Alcon) in September 2005. Toric IOLs can correct 1.50 to 3.00 D of astigmatism. This lens also is available in aspheric versions for crisper vision. Different models also can filter potentially damaging ultra-violet or blue light.
Risks include poor vision due to the lens rotating out of position, with the possibility of further surgery to reposition or replace the IOL. These can be discussed with your cataract surgeon at Northeastern Eye Institute.
