Will a cararact operation correct astigmatism?

Question

Is it necessary for the eye surgeon who replaces a defective natural lens with an artificial lens (cataract surgery) to do an extra procedure to correct astigmatism or will the perfect artificial lens permit at least 20-30 eyesight? Or is the astigmatism caused by some other part of the eye that needs to be changed by the surgeon before the cataract surgery. I think that eyeglasses will correct astigmatism if it exists after the cataract surgery. If additional pre-cataract surgery is necessary to correct for astigmatism, what actual procedures are involved?

Answer 1

Irregular curvature ofthe cornea causes astigmatism, so the lens replacement will not correct it.  Astigmatism is treated with glasses, or contact lenses, or laser surgery.
