Toric intraocular lenses are specialised monofocal lenses and are often the best option for people with astigmatism.
Astigmatism is caused by an irregular shape of the cornea that gives you some degree of blurred vision at all distances. Toric intraocular lenses give you focused vision at a single distance and also correct your astigmatism so you may not need distance glasses after surgery.
As with standard monofocal lenses, however, you will still need reading glasses to see objects clearly up close. If your degree of astigmatism is too great for a toric IOL to address in full, your doctor may recommend that you have an additional procedure.
At the time of cataract surgery or soon afterward, LASIK and limbal relaxing incisions may help to fully correct your astigmatism in combination with a toric IOL.
Toric intraocular are an excellent choice if you:
- Have astigmatism as well as cataracts.
- Don’t mind wearing glasses or contact lenses for some distances.
- Are less comfortable adapting to change and learning new skills.
- Wish to avoid a possible increased risk of some night vision symptoms
Monovision may also be a good option for people with astigmatism who wish to minimize their dependence on glasses and who adapt to change more easily.
A good way to correct astigmatism as well as cataracts
If you have astigmatism in addition to cataracts, cataract treatment with a toric IOL can often address it, making your vision even clearer after surgery than it was before you developed cataracts. This can also reduce your dependence on glasses or contacts after surgery.
As with all surgery, patients with additional health conditions should ask their doctor what clarity of vision they can reasonably expect in their specific case.
More Information about Toric Intraocular Lens

Because they are monofocal lenses like standard IOLs, toric IOLs only provide clear vision at one distance-near, mid-range or distance. So you can expect that you will need glasses or contacts at all but one of these distances. For most patients, eyesight improvement is most important for distance vision, and they use reading glasses to see close objects clearly, just as many people do before cataracts.
Because astigmatism is caused by an asymmetrical surface of the cornea, toric IOLs have asymmetrical powers of correction. Rarely, a toric IOL may shift its position as your eye heals. If this happens, you will need to have it realigned in a follow-up procedure in order to see clearly again. Sometimes people with astigmatism may need additional procedures such as LASIK or limbal relaxing incisions to reach their best vision.
