What Are Light Adjustable Lenses and How Do They Work?
For decades, choosing an intraocular lens (the artificial lens that replaces your natural lens during cataract surgery) meant making a permanent decision before surgery. You and your eye doctor would do your best to predict what lens power would work, but you couldn’t know for certain until after the lens was already in your eye.
However, the Light Adjustable Lens, also called the LAL, gives you the ability to actually experience your vision and then customize it to match your lifestyle and preferences. With the LAL, you can have much better control and personalization of your vision outcomes after cataract surgery.
Keep reading to learn how the Light Adjustable Lens works, what makes it different from other lens options, and whether it might be the right choice for your eyes.
What Are Light Adjustable Lenses?
Light Adjustable Lenses are the first and only intraocular lenses that can be customized after they’re implanted in your eye. The lens is made from a unique material that contains special light-sensitive molecules.
After you heal from cataract surgery, your eye doctor can use carefully controlled ultraviolet light to reshape the lens while it’s in your eye. This changes how the lens focuses light, which means changing how clearly you see at different distances.
Unlike traditional lenses that come in fixed powers, Light Adjustable Lenses give you flexibility. If your vision isn’t quite right after surgery, you’re not stuck with it. The lens can be adjusted multiple times until your vision is exactly what you want. Once you’re happy with the results, a final light treatment locks in your vision permanently.
How Do Light Adjustable Lenses Work?
The process of getting Light Adjustable Lenses involves a few distinct phases, each designed to give you the best possible outcome.
The Initial Implantation
Your cataract surgery with a Light Adjustable Lens follows the same basic procedure as any cataract surgery.
Your surgeon removes your cloudy natural lens and replaces it with the Light Adjustable Lens. The surgery itself takes about the same amount of time as traditional cataract surgery, and the recovery process is similar too.
After surgery, you’ll focus on healing for a few weeks. You’ll need to wear special UV-protective glasses whenever you’re in bright light or outdoors. This is important because you don’t want any uncontrolled UV light reaching your lens before your scheduled adjustment appointments. These glasses protect your lens and ensure that only the planned adjustments happen at the right time.
The Adjustment Process
About two to three weeks after surgery, once your eye has healed enough to measure your vision accurately, the real magic begins. You’ll come back to Lalin Eye for your first light treatment appointment.
During this visit, your doctor will check your vision and discuss what you’d like to achieve.
The light treatment itself is quick and painless. You’ll sit at a device that looks similar to the instrument used to examine your eyes. This device delivers precise patterns of UV light to specific areas of your lens for about 90 seconds.
You might need two to four of these treatments, spaced a few days apart, to reach your ideal vision. Between treatments, you’ll continue wearing your UV-protective glasses. You’ll also notice your vision changing as each adjustment takes effect. This gives you a real-world preview of what your vision will be like, and you can provide feedback to help guide the next adjustment.
The Lock-In Treatment
Once you and your eye doctor are completely satisfied with your vision, there’s one final step. A lock-in light treatment uses UV light differently to make the lens changes permanent. After this treatment, the lens won’t change anymore, even with UV exposure, so you can stop wearing the protective glasses.
The entire process from surgery to final lock-in typically takes about six to eight weeks. While this is longer than traditional cataract surgery, many patients find the ability to customize their vision well worth the extra visits.
Who Is a Good Candidate for Light Adjustable Lenses?
Light Adjustable Lenses can be an excellent option for many people having cataract surgery, but they do require certain commitments and work best for specific types of patients.
You need to be willing and able to attend multiple follow-up appointments over several weeks. Each adjustment requires a visit to your eye doctor, and you can’t skip these appointments or rush the process. If you travel frequently or have difficulty getting to appointments, this might not be the best lens choice for you.
You must also be diligent about wearing the UV-protective glasses during the adjustment period. Forgetting to wear them outside or in bright light could cause unwanted changes to your lens. If you’re someone who struggles to remember to wear protective eyewear consistently, talk with your doctor about whether this technology is right for you.
Light Adjustable Lenses tend to work particularly well for patients who have specific visual demands or those who want the reassurance of being able to fine-tune their vision. If you’re someone who notices small differences in clarity, or if you have a hobby or profession that requires precise vision, this customizable approach can be especially valuable.
Your overall eye health matters too. Certain eye conditions may affect whether you’re a good candidate. During your consultation at Lalin Eye, your doctor will evaluate your eyes thoroughly and discuss whether Light Adjustable Lenses are appropriate for your situation.
