Toric lens implants are not necessary after cataract surgery, according to Koch Eye Associates. Patients with moderate to significant astigmatism who want to correct it permanently can choose toric lenses for their intraocular lens implants. Alternatively, astigmatic patients can receive basic monofocal lens implants and wear corrective eyeglasses after surgery.
Toric intraocular lens implants effectively correct the focus of astigmatic eyes just as contact lenses do, explains Koch Eye Associates. On rare occasions, patients who receive toric lens implants have to move a lens back in place when it rotates out of its position. However, less than 1 percent of patients have such an experience. Insurance plans typically do not cover toric lens implants.
