Getting a cataract surgery done doesn’t necessarily enable freedom from eyeglasses, especially for patients who suffer from corneal astigmatism and irregular shaped corneas. Fortunately, Toric IOL, special intraocular lenses, has been developed to allow correction of astigmatism during a cataract surgery.
Before, patients suffering from both distance vision problems and astigmatism could only correct their distance vision using a single-focus lens. Astigmatism would still require them to wear spectacles. In some cases, additional surgeries or procedures were required to solve their astigmatism problems.
With Toric IOLs, individuals suffering from cataracts now can eliminate astigmatism along simultaneously. This model of lens can give high visual acuity for long-distance vision and correct astigmatism without the need of a separate surgery or corrective procedures.
