AcrySof® IQ Toric

AcrySof® IQ Toric logoMore than 50% of the population has an astigmatism in one or both eyes. The majority of patients undergoing cataract surgery have some form of astigmatism.  Corneal astigmatism is simply a AcrySof® IQ Toric IOLcondition that causes blurred or double vision due to the cornea of the eye being irregularly shaped. In patients who don’t have an astigmatism, their cornea is regular and round as in the shape of a doorknob or hemisphere.  In patients who have astigmatism, their corneas are more oval-shaped like the back surface of a spoon where there is a difference in the steepness in each direction.  The irregular shape of the cornea causes light rays to not properly focus on the retina (back portion of the eye). Because these light rays are skewed, people with astigmatism need prescription glasses or special contact lenses to correct this condition.
