Monofocal toric intraocular lenses correct astigmatism.
Astigmatism is an abnormal curve of the cornea that causes irregularity and elongation of the image. Such irregularity occurs when the cornea is not spherical but oval, and the image created is not clear or properly focused. Up to 30% of patients or candidates for cataract surgery have this type of refractive error.
The implantation of a toric intraocular lens is a long-term solution for astigmatism and the correction of the image created in the eye.
