Information On Upgraded Toric Intraocular Lenses
Astigmatism is a condition in which both distant and near objects appear blurred. The cornea and lens of the eye are ideally spherical. When one or both are curved more steeply in one meridian than another, the optics take on a toric shape, somewhat like a football. This uneven curvature prevents light rays from focusing to a single point on the retina, blurring the visual image somewhat like a funhouse mirror. Astigmatism often occurs in combination with myopia (nearsightedness) and hyperopia (farsightedness). The Alcon Toric intraocular lens compensates for corneal astigmatism. It has two meridians of different power, which can be aligned with the steep and flat meridians of the cornea. While no guarantee can be made as to the final result, there is a better chance you will be able to see clearly in the distance without glasses if a toric lens is implanted.
