Light Adjustable Lens

Light Adjustable Lens (LAL) Implants

At Eastside Eye Physicians, we are proud to be one of the first providers of the Light Adjustable Lens™ from RXSight® in Michigan. For the first time, your vision can be fine-tuned and optimized to your personal preference after cataract surgery. Adjustability takes cataract surgery to the next level by delivering a lens customized specifically for your eyes, your lifestyle requirements, and the way you actually use your vision every day. Light adjustable intraocular lenses are designed to help patients reach their desired vision after healing.

Patients throughout Macomb County and Metro Detroit visit our Shelby Township and St. Clair Shores offices to learn whether this advanced technology is the right fit for them.

What Is the Light Adjustable Lens?

The Light Adjustable Lens is an intraocular lens (IOL) implanted during cataract removal to replace your cloudy natural lens. What makes this implanted lens different from every other lens implant is what happens next: its lens power can be adjusted after surgery with targeted ultraviolet light to customize your vision.

Traditional IOLs are manufactured to a fixed prescription. Before surgery, your surgeon uses precise measurements and calculations to choose a lens and set a visual target with the goal of giving you the best vision possible, but the eye is a living structure, and healing can shift the final result slightly. With a standard lens, whatever you end up with is what you keep, and any remaining refractive error is typically managed with glasses or contact lenses.

For patients considering cataract surgery who want more personalized vision correction and greater freedom from glasses, the Light Adjustable Lens removes much of that guesswork. After your eye has healed, the implanted lens can be fine-tuned with targeted UV light to change its lens power based on how you actually see in daily life, then locked in once you are happy with the result. Below, you will learn how the Light Adjustable Lens works, what the light treatments and protective eyewear involve, who may be a good candidate, the benefits and tradeoffs to consider, and how to schedule a consultation.

How the Light Adjustable Lens Works

The lens contains photoreactive molecules called macromers. When a precise pattern of UV light is applied to a specific area of the lens, the macromers in that area react and reshape the lens curvature by a controlled amount. Changing the curvature changes the power of the adjustable intraocular lens used during IOL implantation.

This allows your surgeon to correct astigmatism by changing curvature and to make spherical and cylindrical power changes as part of your vision correction after cataract surgery. It also makes it possible to fine-tune the balance between distance and near vision, including customized monovision, where one eye is set slightly toward reading vision and the other toward distance.

Once you and your surgeon reach the desired visual outcome, two lock-in sessions are performed after the final light treatment. Each light treatment lasts approximately 90 seconds. These use up the remaining photoreactive material so the lens becomes permanently locked, and final adjustments are locked in 24 hours after the last treatment.

The Customization Process

Cataract surgery with a Light Adjustable Lens follows the same familiar outpatient process as standard cataract surgery. The customization phase begins afterward, once the eye heals over about 2–4 weeks and the adjustment process can begin.

Vision may be blurry immediately after surgery as a normal part of early recovery.

The same standard cataract surgery risks apply, including infection and inflammation.

Post-Surgery UV Light Treatments

The adjustment phase typically begins two to four weeks after your second eye surgery is completed, once your eye doctor confirms your eyes have healed well enough to begin treatment. During a comprehensive medical eye exam, we measure your vision and discuss how your eyes are performing in the activities that matter most to you, whether that is reading, driving at night, working at a computer, or time on the golf course, so we can select a custom prescription based on your visual target and daily goals.

Based on those results and your goals, your surgeon applies a light treatment in our office using the light delivery device. Each treatment is painless, non-invasive, lasts approximately 90 seconds, and requires no anesthesia beyond dilating drops.

Most patients complete three to five total treatments spaced several days apart, which usually includes two or three light adjustments followed by the two lock-in treatments. Between visits during the adjustment phase, you get to live with the change and decide whether you want additional refinement, and because that fine-tuning happens through office treatments, additional surgery is usually avoided. Very few procedures in eye care offer that kind of test drive before the result is finalized.

Wearing Protective UV Eyewear

Because the lens is designed to respond to ultraviolet light, it must be shielded from all incidental UV exposure until the lock-in treatments are complete. Beginning the day after your first surgery and continuing until your final lock-in visit, you will need to wear UV protective glasses during all waking hours, both outdoors and indoors, to protect the lens from direct sunlight and other outdoor sources during the adjustment phase.

We provide these glasses to you, and our team will review exactly when and how to wear them. You should remove them only when sleeping or applying eye drops, and routine eye drops do not interfere with the process when used as directed. Sunlight through a car window, light from a screen, and standard indoor lighting can all contain enough UV to affect an unprotected lens, so consistent use is essential. Patients who are unable or unwilling to commit to wearing the eyewear as directed are generally not good candidates for this lens.

Once your lock-in treatments are finished, the glasses are no longer needed and your customized vision is permanent. Wearing them consistently throughout treatment supports a successful outcome.

Benefits of Light Adjustable Lens Implants

Patients choose the Light Adjustable Lens for several reasons:

• Personalized results. Your prescription is tailored to your eye after healing rather than predicted in advance.
• Higher accuracy. An FDA study found that patients receiving the Light Adjustable Lens were significantly more likely to achieve 20/20 distance vision without glasses than patients receiving a standard monofocal lens.
• You choose your vision. You experience each adjustment in daily life and give input before anything is locked in.
• Excellent astigmatism correction. Residual astigmatism can often be adjusted after surgery to correct astigmatism without a second procedure.
• A single focal point. Because the lens maintains one focal point, it may reduce night-vision distortions such as glare or halos.
• Customized monovision. If you want to reduce your dependence on reading glasses, monovision can be tested and adjusted rather than committed to blindly.
• A strong option for complex eyes. Patients with previous LASIK, PRK, or RK often have less predictable IOL calculations, and adjustability helps compensate for that.
• Long-term value. For many patients, the investment can mean long-term savings on glasses, contacts, and other vision correction needs.

Is the Light Adjustable Lens Right for You?

The Light Adjustable Lens is an excellent choice for patients who have a visually significant cataract, which often develops as a normal part of the aging process, want the greatest possible freedom from glasses, and are motivated to be involved in refining their own results.

It may not be the best option if you have significant macular or corneal disease, a history of herpetic eye disease, pupils that do not dilate well, difficulty holding steady fixation, or if you take medications that increase sensitivity to UV light. Because the process requires multiple return visits over several weeks, it also works best for patients who are able to keep a consistent follow-up schedule and are not traveling during that window.

The only way to know for certain is a thorough evaluation. During your medical eye exam at Eastside Eye Physicians, we assess the health of your cornea, retina, and optic nerve, take detailed measurements of your eyes, and talk through your visual priorities before recommending a lens.
