Astigmatism is caused by the cornea being more curved in one direction than the other, causing blurred vision. Toric intraocular lenses (IOLs) are specially shaped IOLs designed to offset that imbalance.
Toric IOLs offer cataract patients or patients with presbyopia vision correction that reduces or eliminates corneal astigmatism and delivers significantly improved distance vision without the need for glasses or contacts.
Approximately 95% of patients with astigmatism see clearly with a Toric IOL.
Patients with a standard IOL who have astigmatism have about a 25% chance of seeing clearly without glasses.
Once implanted and aligned inside the eye, Toric IOLs stay fixed in place, which then results in eliminating pre-existing astigmatism.
