Can I Choose the Vivity Lens If I Have Astigmatism?

Having the best possible vision is one element of a healthy life. Thanks to modern medicine, you can achieve that even after developing cataracts.

When cataracts form in your eyes, your natural lenses get cloudy and white. During cataract surgery, they get removed from your eyes and replaced.

The replacement lens is an intraocular lens or IOL. Depending on the type of IOL you select, you can get clear, basic vision or the sharpest vision you’ve ever had.

For the best results, you’ll need a premium IOL. Certain IOLs can also correct astigmatism during cataract surgery.

The Vivity IOL can provide enhanced vision after cataract surgery, even if you have astigmatism. Keep reading to learn more about the Vivity IOL and how it can correct your astigmatism!

What Are IOLs?

An intraocular lens or IOL is a replacement lens used during cataract surgery. It performs the same function as your natural lens of helping to focus light onto your retina.

Most IOLs can counteract the effects of nearsightedness or farsightedness. But, it takes a particular type of IOL to correct astigmatism.

Nearsightedness and farsightedness can vary in intensity. But the principal causes of each, and the resulting vision errors, are similar for both.

Both result from a misshapen cornea. Nearsightedness occurs because of a too steeply curved cornea that focuses light in front of your retina.

Farsightedness is the opposite. It occurs when your cornea doesn’t have enough curvature, which focuses light behind your retina.

Unlike the other two common refractive errors, astigmatism causes light to focus on multiple points inside your eye. This scattering is due to an irregularly shaped cornea.

It results in blurry and unfocused vision at multiple ranges. Treating astigmatism is more complicated than treatment for nearsightedness or farsightedness.

The irregularities in your cornea are less predictable with astigmatism than other refractive errors. To correct astigmatism with an IOL, you need a toric model IOL.

How Do The Different Kinds of IOLs Work?

The most basic form of IOL called a monofocal IOL, can only correct vision at a single distance. It can give you clear eyesight either up-close or far away.

After cataract surgery with a monofocal IOL, you will still need to use glasses. Depending on which distance your monofocal corrects, you will need glasses for the opposite distance.

Premium IOLs come in several varieties. Multifocal IOLs can focus vision from multiple distances. They have several focal points built into the lens to refract light from various distances.

Accommodating IOLs move inside your eye like your natural lens to change focus. Toric model IOLs are custom-made and fit to correct your astigmatism.

If an IOL comes in a toric model, it can correct your astigmatism while you also get rid of your cataracts. The Vivity IOL corrects astigmatism because it has an available toric model.

What Sets The Vivity IOL Apart?

The Vivity IOL provides stunning visual clarity over far distances and excellent vision at mid ranges. It uses a technology called non-diffractive X-WAVE Technology to give you seamless eyesight at multiple distances.

The Vivity lens has two transition elements that shift light without causing it to split. These seamless focal points give you an excellent chance of never needing glasses after cataract surgery. And, because it comes in a toric model, you have a good chance of never needing glasses, even if you have astigmatism.
