Toric IOLs

Advances in Intraocular Lens (IOL) technology now provide a reliable and effective option for patients with astigmatism. Until the recent introduction of Toric IOLs, people who were considered candidates for intraocular lenses could only have their nearsightedness and farsightedness corrected during lens implant surgery. Patients with astigmatism had to either have corneal refractive surgery (LASIK, PRK, or Limbal Relaxation Incisions) after lens implant surgery or remain dependent on glasses or contacts. 

Astigmatism is caused by the cornea being more curved in one direction than the other, much like a football. Toric IOLs are specially shaped IOLs designed to offset the imbalance created by the irregular shape of the cornea. Once implanted and aligned inside the eye, they stay fixed in place thereby eliminating pre-existing astigmatism.

There are several manufacturers of Toric IOLs that are available to correct various amounts of astigmatism. Your doctor will select the Toric IOL that is best suited for your eye condition. Toric IOLs are considered “premium” IOLs which means there will be additional costs associated with these lenses.
