Ready to clear the dull, blurry vision and enjoy crisp, clear vision once again? When planning for cataract surgery, consider the benefits different types of intraocular lens (IOL) implant options available to you. These biocompatible, surgical-grade implantable lenses offer dramatic results for those who are ready to clear the blur that comes from cataracts.

In the interest of keeping things simple, we’ll discuss the two primary classes of IOLs: monofocal IOL and multifocal IOL. This overview should give you some idea of which option may be right for you.

Basic Monofocal IOLs

Basic Monofocal IOLs are what’s called a “fixed” focal distance lens, which means they are created to correct vision for near, intermediate or far focus.

Multifocal IOLs

Multifocal IOLs provide the patient with a combination of focal points (from among near, midrange and distance vision) within each lens for better overall vision.

Which IOL should I choose: monofocal or multifocal lens?

The best lens implant for you will depend on how you want vision correction to improve your quality of life. If you’re an avid golfer, enjoy reading, are generally active, spend time on the computer or tablet, or enjoy artful hobbies, a multifocal IOL is often an ideal choice. Rather than constantly depending on reading glasses or bifocals, the multifocal IOL can reduce or eliminate the need for corrective eyewear for many of these types of activities.

In some cases, a combination of implantable lenses is ideal, such as a monofocal IOL focused for distance and one multifocal lens for everything else. Your eye surgeon will ask you about your work, lifestyle and vision goals to help you arrive at a treatment that works best for you.

In determining the treatment plan that will give you the best vision results, your surgeon may also discuss with you several subtypes of implantable contact lenses to further customize your treatment:

Accommodating IOL is designed for clear near vision, reducing or eliminating the need for reading glasses.

Conventional Spherical IOL can be customized to tailor visual acuity to a single focal point, near or far. That means the patient can have lenses focused for reading so they can reduce the need for reading glasses, or they can choose to focus them for distance instead. 

Aspheric IOL closely matches the natural lens shape to provide excellent vision correction in low light and for patients with larger pupils.

Toric IOL offers focus in different areas of the lens and is appropriate to treat astigmatism or nearsightedness. 

Clearly, there is much to consider when deciding which vision correction procedure is right for you. To set yourself up for success, spend some time thinking about what aspects of your life are most important to you and how better vision can enhance your enjoyment of them.
