Understanding the Differences Between Light Adjustable Lenses and Multifocal IOLs

When considering cataract surgery in Bismarck, North Dakota, many patients want the most advanced option for restoring clear, customized vision. One question we frequently hear at Dakota Eye Institute is: “Are Light Adjustable Lenses (LALs) multifocal?”

The short answer: No, Light Adjustable Lenses are not multifocal.
However, they offer a unique benefit that even multifocal lenses can’t — the ability to fine-tune vision after cataract surgery with light treatments.

In this article, we’ll explain the differences between Light Adjustable Lenses vs. multifocal lenses, how RxSight LAL lenses work, and who might benefit from each.

What Are Light Adjustable Lenses?

The Light Adjustable Lens, or LAL, is a groundbreaking cataract lens developed by RxSight. Unlike traditional intraocular lenses (IOLs), the LAL can be adjusted after surgery using controlled ultraviolet (UV) light. This allows your cataract surgeon to fine-tune your prescription for the sharpest vision possible.

Key Features:

• Single-focus monofocal design
• Offers customizable vision after surgery
• Great for patients with a history of LASIK, PRK, or complex prescriptions
• High success rate using light adjustable lenses

So, while the LAL is not multifocal, its post-surgical adjustability offers a level of precision not available with traditional lenses.

What Are Multifocal Lenses?

Multifocal IOLs are designed to give you vision at multiple distances — near, intermediate, and far — all at once. They’re a popular choice for patients hoping to reduce their need for reading glasses after cataract surgery.

However, multifocal lenses:

• Cannot be adjusted after surgery
• May cause glare or halos at night
• May not offer the same visual clarity as LALs for certain patients

LAL vs. Multifocal: What’s the Difference?

So, Are Light Adjustable Lenses Worth It If You Want Multifocal Vision?

If you want to reduce your dependency on glasses after surgery, Light Adjustable Lenses can still help. Using a technique called monovision, your cataract surgeon can adjust one eye for distance and the other for near vision, offering functional results similar to a multifocal lens.

However, if you need full multifocal capabilities and don’t want monovision, a multifocal IOL might be the better option.

Pros and Cons of Light Adjustable Lenses

Pros

• Personalized vision correction
• Ideal for patients with prior laser eye surgery
• Fewer night vision issues than some multifocal lenses
• Available through expert cataract surgeons in Bismarck

Cons

• Not multifocal by design
• Requires UV protection glasses post-op
• Higher light adjustable lens cost
• Requires multiple follow-up appointments for adjustments

What Patients Say

According to light adjustable lens patient reviews, many people report sharper vision and greater satisfaction compared to standard cataract lenses — especially when managed by experienced providers like Dakota Eye Institute. While LALs may not eliminate glasses for every situation, most patients enjoy dramatically improved vision clarity and comfort.

Light Adjustable Lens Cost vs. Multifocal Lens Cost

Both options are considered premium cataract lenses and are typically not fully covered by insurance. The cost of the light adjustable lens includes the lens itself and the adjustment visits. We’re happy to discuss all your cataract surgery cost options, including HSA/FSA usage and financing.
