Cataract Lens Types: Toric, Multifocal and EDOF Intraocular Lenses

Cataract Lens Types: Toric, Multifocal and EDOF Intraocular Lenses

Cataract surgery is considered one of the safest and most successful surgeries performed today. The surgery involves removing the cloudy lens and replacing it with an artificial lens called an intraocular lens (IOL). An IOL is a clear, plastic lens that requires no care and remains permanently in the eye.

IOLs not only treat cataracts but also correct vision. You can select a standard IOL that corrects near, intermediate or distance vision, or a premium IOL that offers enhanced features. Here are some of the most popular types of premium IOLs:

Toric IOLs

Toric IOLs are designed to treat astigmatism – which is characterized by an irregularly shaped cornea or lens. In patients with astigmatism, the cornea does not properly refract light rays onto the retina and objects appear blurry and distorted. A toric IOL can correct up to 4.50 diopters of corneal astigmatism.

Multifocal IOLs

Multifocal IOLs correct a range of visual fields. The newest designs split light into several focal points to provide high quality vision. Patients who have presbyopia (impaired near vision) and astigmatism, may have success with multifocal IOLs. This type of lens often eliminates the need for glasses altogether.

Extended Depth of Focus (EDOF) IOLs

The EDOF IOL is designed to extend range of vision, including far, intermediate and near vision. This lens lengthens the spectrum of focus and provides clear vision at different distances. Because light is not focused at two distinct points, patients notice a smooth transition from far to near with reduced glare and halos.

Most cataract surgeries can be completed in 30 minutes or less in an ambulatory surgery center (ASC). After a short recovery at home, you can expect to resume your regular activities within a few days. If it is nearing time for you to have cataract surgery, talk to your ophthalmologist about which prescription intraocular lens is right for you. Your cost-share responsibility is higher with a premium IOL, but the benefits may be worth the additional investment.
