Which Type of IOLs Should You Consider for Cataract Surgery?

Different Types of Lenses for Cataract Surgery

When the eye surgeon removes the clouded lens from the eye, they replace it with an artificial lens – also known as an intraocular lens (IOL). The new lens is designed to resemble the eye’s natural lens, which is crystalline clear. As a result, most patients who have cataract surgery see their symptoms disappear.

Did you know that the first intraocular lens was implanted all the way back in 1949? A lot has changed over the past 75 years – not just in the procedure, but in the actual IOL itself. Today, doctors have a variety of different types of lenses to choose from when recommending cataract surgery to a patient.

Let’s take a look at some of the most prominent types of intraocular lenses available today:

1. Monofocal Lenses

Also known as a single focal-powered lens, a monofocal lens has the ability to allow one point of focus – it'll either correct near vision, correct intermediate vision, or correct distance vision. A majority of patients – not all – will have their intraocular lens implants set for distance vision, but will still need glasses to see objects up close clearly.

2. Multifocal IOLs

As the name suggests, multifocal lenses allow for multiple focal points. The lens has corrective zones built into it, allowing the individual to see both near objects and distant objects clearly – a similar idea to the bifocal eyeglass lens, but the multifocal IOL allows for both near and distant vision at all times.

3. Extended Depth-of-Focus (EDOF) IOLs

Also known as Extended Range of Vision, an Extended Depth-of-Focus lens creates a single elongated focal point – unlike a multifocal lens, which allows for multiple focal points. EDOF lenses see that focal point stretched to allow distance and intermediate vision. They’re primarily used with presbyopia patients.

4. Accommodative Lenses

Accommodative lenses, sometimes referred to as accommodating lenses, allow for dynamic focusing at various distances – meaning the individual can see clearly from near, intermediate, and long distances. What makes this lens unique is its ability to use natural movements of the eye to change its focus.

5. Toric Lens Implants

Toric lenses are unique in their ability to help correct astigmatism following cataract surgery, while also improving distance vision. Toric IOLs available in both monofocal and presbyopia-correcting lenses. It allows those who undergo cataract surgery to avoid having to use eyeglasses to correct astigmatism.

6. Light-Adjustable Lens (LAL)

Perhaps one of the newest advancements with intraocular lenses, the light-adjustable lens allows for further customization and personalization after the lens is implanted into the eye. As a result, adjustments can be made after surgery to help account for any vision changes that occur during the procedure.



How to Choose the Right Type of Lens for Cataract Surgery

Thanks to the wide range of cataract lens options available today, doctors can now customize a patient’s experience with cataract surgery. With so many cataract surgery lens options to choose from, most patients are going to have one primary question on their mind – how do I know which one is right for me?

Here are some of the factors you should consider when choosing the right type of lens for cataract surgery:

• Certain IOLs are more expensive than others, so take your budget into consideration
• Do you have any refractive errors (nearsightedness, farsightedness, astigmatism) you’d like to address with the new lens?
• If you plan on doing a lot of driving at night, you might want to consider a monofocal lens.
• Some IOLs aren’t recommended for patients with certain medical conditions and eye problems, so keep that in mind.

This might seem like a lot to consider, but don’t panic – that’s where your ophthalmologist comes in handy. Before they perform the procedure, they’ll help you navigate all your options and recommend the lens that best suits your wants and needs. Their goal is to help you feel comfortable with the results.
