Cataract and Cornea Astigmatism Correction
A common refractive condition caused by either an irregularity in the curvature of the cornea (corneal astigmatism) or the lens (lenticular astigmatism), astigmatism results in the blurring of all images, whether they are near or far. This usually occurs when the cornea is shaped like a football with a steeper curve in one direction and a flatter curve in the other, rather than round like a basketball. This uneven shape causes light rays entering the eye to focus on more than one point, rather than only on the retina as they should.
Referred to as “the emerging standard” and a “triumphant moment in cataract surgery,” the AcrySof® IQ Toric IOL corrects for cataracts with pre-existing astigmatism simultaneously by delivering more precise, predictable outcomes and quality distance vision—without the need for glasses following surgery.
The AcrySof® IQ Toric IOL may also eliminate, in many cases, the need for limbal relaxing incisions, a technique in which incisions are made at the edge of the cornea to cause it to heal in a more spherical shape.
The latest in a long line of IOL innovations from Alcon, the AcrySof® IQ Toric IOL takes the most trusted platform for precise astigmatism correction and adds the enhanced image quality of an aspheric lens. The chromophore filters blue light without impacting color vision or the quality of vision. Some visual effects may be expected including halos around light during low light or in night time conditions.
