Is the Light Adjustable Lens Worth It?

Quick answer: The Light Adjustable Lens is usually the most expensive lens option in cataract surgery, and it demands about five extra office visits for adjustments and lock-ins. What you buy with that money and time is precision: published registries put it at 93 to 94% of eyes within half a diopter of target, about half a step of a glasses prescription, versus roughly 80% for conventional lenses with the best formulas (separate studies, not a head-to-head). If being as independent from glasses as possible matters to you, I think the extra cost is worth it. If you're fine wearing glasses, a standard lens gives excellent vision and you can skip the expense entirely.

Light Adjustable Lens pros and cons, as I lay them out in my own practice.

Cons

Usually the most expensive lens option, and the upgrade is out of pocket.
About five extra office visits in my practice, sometimes more if dry eye delays an adjustment; you get up to three adjustments and two lock-ins.
UV-protective glasses until the lock-ins are done.
Not the right fit if you're fine wearing glasses or can't commit to the visits. The standard lens gives excellent vision.

Pros

Your lens power is fine-tuned after your eyes heal instead of relying only on the pre-surgery prediction.
Registries report 93 to 94% of eyes within half a diopter of target, versus about 80% for conventional lenses with the best formulas (separate studies, not a head-to-head).
Each adjustment is about 90 seconds of light per eye.
Suits patients who want to be as independent from glasses as possible.

Patients ask me this one straight out: "Doc, is the adjustable lens really worth the extra money?" In my own exam room I lead with the two disadvantages, so that's where we'll start.

The two disadvantages I tell every patient

It's the most expensive lens. It's the newest lens, and it costs the most. Insurance covers the standard lens; everything about the adjustable one is an out-of-pocket upgrade.

It also requires a lot of extra follow-up visits, and in my practice you should plan on about five extra visits compared to a standard or trifocal lens, sometimes more.

How many follow-up visits does the Light Adjustable Lens need?

At each adjustment visit, our optometrist checks the glasses prescription in both eyes and works with you to find a prescription that makes you happy with both eyes working together. Once you're happy, they dilate your eyes, which takes some time. Then we do the light treatment, about 90 seconds of light per eye. We send you home, and a week or so later you come back and do the same thing again. You get up to three adjustments, and then two lock-in procedures that make the result permanent.

If we can't get an accurate prescription, the adjustment waits, and the most common reason is dry eye. When your eyes are really dry, there's sometimes a lot of intensive dry eye treatment required before we can trust the measurements. I've written about how many adjustments patients typically need and what lock-in actually is if you want the full timeline.

So yes, the Light Adjustable Lens is a lot of extra work, for you and for us. That's partially why it's the most expensive option.

What you get for it

Even with the most accurate formulas, conventional lens power selection lands within half a diopter of target about 80% of the time. With the adjustable lens, we don't have to predict. We measure your real prescription after your eyes heal and dial the lens in, and the published registries report 93 to 94% of eyes within half a diopter. Those are different studies on different patients, so it's not a head-to-head. I've compared the LAL and the LAL+ and the LAL against the PanOptix Pro trifocal separately if you're weighing lens types rather than cost.

That precision really matters if you're trying to become independent from glasses. A lens that lands a little off target can mean you paid for premium vision and still reach for glasses.

So is it worth it?

You're going to have these lenses in your eyes for the rest of your life. You'll be looking through them every waking moment. Getting the lens on target, getting what you're actually hoping for rather than leaving it up to chance, is worth paying for. People spend more on a designer purse or a watch than on the artificial lens they'll use every waking moment for the rest of their life. So if glasses independence is very important to you, I do think the extra expense is worth it.

It's also important to say that you do not need this lens. The standard lens that insurance covers gives excellent vision, and if you don't mind wearing glasses, it's a great choice and the adjustable lens is money you don't need to spend. Nobody should talk you into it. It's also not the right fit if you can't commit to those visits.

Common questions

How much does the Light Adjustable Lens cost?

It's typically the most expensive lens option in cataract surgery, and the full amount is out of pocket because insurance covers only the standard lens. In my practice the price includes the lens itself, the adjustment and lock-in visits, and the UV-protective glasses, so the adjustments aren't billed separately as you go. Exact pricing varies by practice and by what your surgery involves, so ask for the all-in number at your consultation, and ask specifically whether the adjustments and lock-ins are included.

Why does the Light Adjustable Lens cost more than other premium lenses?

The lens itself costs the practice more than a fixed lens, and the practice has to own the light delivery device and staff about five extra visits for every patient. You are paying for the lens and for the extra time it takes to get it right, which is part of why the number differs from one practice to the next. The standard lens that insurance covers gives excellent vision, so the question is whether the fine-tuning is worth it to you.

How many extra visits does the LAL really take?

Plan on about five extra visits compared to a standard or trifocal lens: adjustment visits (up to three, each with a prescription check, dilation, and a light treatment for each eye) plus two lock-ins. Dry eye or an unstable prescription can stretch the schedule further.

Is the LAL worth it if I don't mind wearing glasses?

Probably not. I implant this lens every week and I still tell people that. The standard lens gives excellent vision with glasses, and the adjustable lens's advantage is precision for people chasing glasses independence. If glasses don't bother you, put the money elsewhere.

Does insurance ever cover the Light Adjustable Lens?

No. Insurance pays for the surgery and the standard lens. Anything premium, including this one, is out of pocket, and this one usually costs the most.

Is it worth it for your eyes?

Hopefully this answers the cost question and puts you more at ease. Whether the lens fits your eyes at all is the bigger question, and that one takes a consultation with exact numbers in hand. OC Eye Associates, Irvine.
