Treat Cataracts and Astigmatism with a Toric IOL

Toric intraocular lenses (IOLs) allow cataract patients with astigmatism to achieve crisper, clearer vision. The specialists at TLC Yonge Eglinton Laser Eye Centre in Toronto, ON, are proud to offer these advanced lenses. By choosing a toric IOL, individuals with a cataract can reduce or even eliminate their need for glasses or contacts after surgery.

What are Toric Intraocular Lenses?

If you have an astigmatism and wear contacts, you are likely familiar with toric lenses. A toric IOL is similar to a toric contact lens. Toric lenses have different powers across the device, and these correct the visual errors associated with the astigmatism. To properly correct the astigmatism, toric lenses cannot rotate the way regular contact lenses do. As such, they are usually weighted at the bottom, which prevents rotation.

For patients with cataracts and an astigmatism, toric IOLs are the only way to eliminate the need for contacts or glasses after surgery.

Toric IOLs have a similar design feature. Different lens brands vary slightly, but most have markers like dots that allow the surgeon to see the correct orientation. Once the IOL is implanted, the surgeon can adjust the lens so it aligns correctly with the astigmatism. 

Implantation of Toric IOLs

The only way to cure cataracts is with the surgical placement of IOLs. There are a variety of different types of IOLs, but only toric options can correct astigmatism in addition to other vision problems like nearsightedness. Although less common, we may recommend IOLs for patients who are not good candidates for other laser vision correction procedures.

Intraocular lenses are typically placed one eye at a time. This means your first eye must heal before we operate on the second eye. On the day of surgery, we will numb the eye with a local anesthetic. Then the surgeon will create a small incision in the eye. The natural lens is broken into pieces and removed. The surgeon then places the flexible toric IOL, which will unfold within the eye. After it unfolds, the surgeon can rotate the IOL so it is aligned to correct the astigmatism.

The procedure takes about 30 minutes to complete. Patients may need several days off of work to heal. After two to three weeks, we can place the toric IOL into the second eye.

Benefits of Choosing Toric IOLs

For patients with cataracts and an astigmatism, toric IOLs are the only way to eliminate the need for contacts or glasses after surgery. Other types of IOLs can address nearsightedness and farsightedness, but they cannot correct an astigmatism. Toric IOLs are also a good alternative for patients whose astigmatism and other complications prevents them from qualifying for LASIK or another corrective procedure.
