Toric lens implants for patients with corneal astigmatism

Descripción:

Toric lenses are suitable for patients with corneal astigmatism. Astigmatism is a condition when the cornea, the front part of the eye, is like a rugby ball rather than a sphere. Toric lenses can correct astigmatism in the prescription. When a patient has a significant degree of astigmatism, a toric lens would be beneficial to help spectacle independence. These lenses have special marks at the axis of the astigmatism. They require careful pre-operative planning of the level of the astigmatism. They are inserted inside the eye after careful marking of the astigmatism meridian on the cornea and the lens is aligned along this desired meridian.
