Toric contact lenses
Toric contact lenses are used to correct astigmatism. Certain patients have what is known as corneal astigmatism. What that means is, instead of the cornea being shaped in a round fashion like a basketball, it has a more oblong shape in one of its positions, one of the parts of the cornea – more like a football rather than a basketball. Toric lenses are used to correct this astigmatism in the contact lens. The main advantage for people with astigmatism is they can get better vision with a toric contact lens because the astigmatism is corrected as compared to a regular soft contact lens; however, sometimes the contact lens may be a little less comfortable to wear and may de-center.
