If you’re preparing for cataract surgery, one of the most important decisions you’ll make with your surgeon is which type of intraocular lens (IOL) will replace your clouded natural lens. While cataract surgery itself is a highly successful and straightforward procedure, the IOL you choose plays a major role in determining how well you’ll see afterward—and whether you’ll still need glasses.

As a board-certified ophthalmologist and cataract specialist, Dr. Brent Bellotte helps each patient navigate this decision based on their vision goals, lifestyle, and unique eye anatomy. In this article, we’ll break down the differences between monofocal, multifocal, and toric IOLs, and how to decide which one may be best for you.

What Is an Intraocular Lens (IOL)?

During cataract surgery, your eye’s natural lens—which has become cloudy due to cataracts—is removed and replaced with a clear, artificial lens called an intraocular lens (IOL). IOLs help refocus light onto the retina, restoring vision. These lenses are permanent and designed to last a lifetime.

The type of IOL implanted will determine whether you’ll still need glasses for reading, distance, or both after surgery.

Monofocal IOLs: The Standard Option

Best For: Patients who want clear distance vision and don’t mind wearing reading glasses.

Monofocal IOLs are the most commonly used lenses in cataract surgery and are often covered by insurance or Medicare. They are designed to provide clear vision at a single distance—usually for far vision.

With monofocal IOLs, most patients will still need reading glasses or bifocals for close-up tasks like reading, using a smartphone, or sewing.

Pros:

• Proven, reliable results

• Lower cost or full insurance coverage

• Fewer visual disturbances (e.g., halos or glare)

Considerations:

• You will likely need glasses for reading or intermediate tasks

• Not ideal if you want to minimize dependence on eyewear

Multifocal IOLs: Greater Range of Vision

Best For: Patients who want independence from glasses for both distance and near vision.

Multifocal IOLs are premium lenses that offer multiple focal points—meaning they can help you see clearly at both distance and near ranges. These lenses use advanced optical technology to split light and provide a fuller range of vision.

Multifocal IOLs significantly reduce the need for glasses, although some patients may still need them for specific tasks like prolonged computer use.

Pros:

• Reduced dependence on glasses or contacts

• Clear vision at multiple distances

• Popular among active patients

Considerations:

• Not typically covered by insurance (out-of-pocket expense)

• May cause glare or halos, especially at night

• Requires a detailed evaluation to determine candidacy

Toric IOLs: Designed for Astigmatism

Best For: Patients with moderate to high astigmatism.

Astigmatism is a common condition where the cornea or lens has an irregular shape, leading to blurred or distorted vision. Toric IOLs are specifically designed to correct this condition during cataract surgery.

These lenses have built-in astigmatism correction, helping you achieve sharper vision without needing glasses for distance. However, like monofocal IOLs, you may still need glasses for reading or close-up work.

Pros:

• Corrects astigmatism at the time of cataract surgery

• Improves uncorrected distance vision

• Helps reduce dependence on prescription glasses

Considerations:

• May involve additional cost

• Reading glasses are often still needed

How to Choose the Right IOL

Choosing the right IOL isn’t just about what’s available—it’s about what fits your vision needs, eye health, and lifestyle. Dr. Bellotte takes time to evaluate every patient’s goals and offers guidance based on years of experience and thousands of successful procedures.

Here are some factors to consider:

• Do you want to be glasses-free for most activities? Multifocal may be a better fit.

• Do you have astigmatism? A toric IOL may be required.

• Do you prioritize sharp distance vision and don’t mind using reading glasses? Monofocal lenses are a great choice.

• Are you sensitive to visual distortions like halos or glare? Monofocal or toric lenses may provide better clarity.

Dr. Bellotte will also evaluate factors such as pupil size, corneal health, retinal condition, and lifestyle habits when recommending an IOL.

What to Expect from the Process

Before your cataract surgery, you’ll undergo a full eye exam and advanced imaging to assess your candidacy for various lens options. Dr. Bellotte will review these findings with you and explain how each IOL type would perform in your specific case.

The final decision is always collaborative—and guided by a commitment to achieving your clearest possible vision.
