TORIC INTRAOCULAR LENSES
Astigmatism means that the front surface of the eye (the cornea) is shaped like a football instead of a baseball – it has two curves – one longer that the other. Because the eye is only able to focus one curve at a time, the other curve is out of focus. The word astigmatism comes from the Latin “a” meaning without and “stigma” meaning point – without a point focus! Having cataract surgery when there is a significant corneal astigmatism is best corrected by a TORIC astigmatism correction lens.
