If you are getting cataract surgery, one of the biggest decisions is which type of intraocular lens (IOL) to have implanted. IOLs are artificial lenses placed in the eye. They replace the lens removed during cataract surgery.

Today's IOLs correct vision and reduce the need for glasses or contacts after surgery. Here is an overview of the main types of IOLs surgeons use most often. It will cover the benefits, potential disadvantages, and situations each lens best suits.

Monofocal IOLs

Monofocal IOLs are the most common type of lens implanted during cataract surgery. They have a single focus, allowing one to have good vision for distance or near objects. 

Surgeons frequently use the Alcon Clareon Monofocal IOL. It provides excellent distance vision and a reduced need for glasses after healing. It is a great option for active lifestyles. 

The Bausch + Lomb IC-8 Apthera and enVista IOLs are both premium monofocal IOLs. However, they differ in their design and features. The IC-8 Apthera is a small aperture IOL that provides an extended depth of focus. The enVista is a glistening-free IOL. Which IOL is right for you will depend on your needs and preferences.

Toric IOLs

Toric IOLs correct astigmatism along with nearsightedness or farsightedness. Astigmatism causes blurred vision from irregularly shaped corneas. Many patients choose toric lenses like the Alcon Clareon Toric or the Johnson & Johnson TECNIS Eyhance. These provide crisp, clear vision at all distances. The main drawback of toric IOLs is the extra cost over standard monofocal lenses. However, for those with high astigmatism, the benefits often outweigh the expense.

EDOF IOLs

Extended depth of focus (EDOF) IOLs are newer lens options that give an extended range of vision whereby one can see clearly for both distance and near tasks. The Alcon Clareon Vivity EDOF IOL is an excellent choice for those seeking a reduced need for glasses without the potential side effects of multifocal lenses. It uses a unique design to achieve exceptional visual range. The one drawback is that vision may be less sharp for reading fine print than multifocal IOL options. But ease of adaptation is better with EDOF lenses.

Multifocal IOLs

Multifocal IOLs have different zones for near, intermediate, and distance vision. They allow clear vision at most ranges without wearing glasses. Many opt for the Johnson & Johnson TECNIS Symfony due to its excellent focus range. 

The PanOptix by Alcon is another popular choice, providing sharp near vision. The tradeoff is possible side effects like halos at night. Multifocal lenses also require a period of neuro-adaptation to get used to the zones. However, 85% of wearers report high satisfaction.

Light-Adjustable IOLs

Light-adjustable lenses use a unique technology that allows ophthalmologists to customize and enhance vision after surgery using a harmless laser. The RxSight Light Adjustable Lens is the most advanced option for patients who want to be less dependent on glasses. 

The eye doctor performs refinements during an office visit after healing. The only disadvantages are added costs due to the customization process and limited availability. But it is a revolutionary choice for some patients.

Which IOL Is Right for You?

When choosing an IOL, there are a few key factors surgeons consider:

• The patient's eye health and measurements

• The patient's visual needs and lifestyle

• The patient's occupation and hobbies

• The patient's willingness to pay added out-of-pocket costs if needed

During a cataract evaluation, eye doctors thoroughly discuss all IOL options. Excellent choices are available to reduce the need for glasses while maximizing visual clarity. Cataract surgery is now safer and more effective than ever. With advancements in IOL technology, finding a customized solution offering quality vision after the procedure is easier.

Bottom Line

If cataracts are present, one should not put off surgery out of concern for subpar results. Schedule an exam to review the IOLs best suited for your eyes and visual goals.
