“My LASIK Wore Off” Is a Myth: What Actually Changed

Gregg Feinerman MD, FACS

September 2, 2026

I have been performing LASIK since 1998. Some of the patients I treated in the earliest years of my career are now in their late 50s, and every few weeks one of them sits down in my exam chair and says the same sentence: “I think my LASIK wore off.”

I understand why it feels that way. Twenty years ago you walked out of surgery seeing the clock across the room. Now you are holding the menu at arm’s length, squinting at your phone, and buying reading glasses in three-packs. Something obviously changed.

But it almost never was the LASIK. In this post I will explain what actually happened inside your eye, why more laser is usually the wrong answer, and what your real options are today.

Why “LASIK wore off” is almost always the wrong diagnosis

LASIK reshapes the cornea, the clear front window of the eye. Once the cornea heals, that new shape is remarkably stable. The laser does not fade, and the tissue does not grow back.

What LASIK never touched is the natural lens sitting behind your iris. That lens is what changes with age, and it changes in every human eye, LASIK or not.

In your 20s and 30s the natural lens is soft and flexible. It changes shape in a fraction of a second to bring near objects into focus. Starting in your mid-40s, the lens stiffens. By your 50s it has lost most of its ability to focus up close, and it has begun to scatter light and lose clarity. Surgeons call this progression dysfunctional lens syndrome. Patients call it “my arms are too short.”

So the cornea that LASIK built is still doing its job for distance. The lens behind it stopped doing its job for near. The result feels exactly like your LASIK failing, when in fact a different part of the eye aged on schedule.

Clinical note: two separate structures, two separate problems

LASIK corrects the cornea. Presbyopia and early cataract come from the natural lens. A 2026 review in Review of Ophthalmology put it plainly: age-related lens changes are often responsible for patients’ assumptions that their “LASIK wore off,” and presbyopia is fundamentally a lens disease. That is why the fix, when one is needed, is usually a lens procedure rather than more laser. Read more in our guide to dysfunctional lens syndrome.

When LASIK wore off for real: true regression, and how to tell the difference

I want to be fair to the question, because true regression exists. In a small number of eyes, especially those treated for higher prescriptions, the cornea can drift slightly back toward the original prescription. When it happens, it typically shows up in the first year or two after surgery, it is usually small, and it affects distance vision.

The pattern I see in patients over 45 is different in every way. The change arrives 15 to 25 years after surgery. Distance vision is often still quite good. The complaint is near vision first, then dim restaurants, then night driving. That is the signature of the lens, not the cornea.

In my office we do not guess. Ray-tracing aberrometry (the iTrace) measures the optical quality of the cornea and the lens separately, and gives the lens a score called the Dysfunctional Lens Index. If your cornea is still delivering crisp optics and your lens score has dropped, we have our answer, and it is not a laser answer.

Why more LASIK is usually the wrong fix after 45

Patients sometimes ask for a LASIK “touch-up” to restore what they had. For a stable prescription in the early 40s, that can still be reasonable. Over 45, I generally do not recommend LASIK, because the aging lens, not the cornea, is usually the real problem.

Here is the logic. A laser enhancement can only reshape the cornea. If the lens is what stopped focusing, reshaping the cornea does nothing for near vision, and it removes a little more tissue from a cornea that has already been treated once. Monovision LASIK (one eye set for distance, one for near) can buy a few years for some patients, but it trades away depth perception and does nothing to stop the lens from continuing to age. A few years later, you are back in the chair with the same complaint plus an early cataract.

Treating the lens addresses the actual cause. It also happens to be the only vision correction that removes a future surgery from your life, because a replaced lens can never develop a cataract.

What actually changed: your lens, and what to do about it

If the lens is the problem, the modern solution is to replace it. Done before a cataract has formed, that procedure is called refractive lens exchange (RLE). Done after, it is called cataract surgery. They are the same operation on the same platform; the difference is timing and who pays.

RLE takes 15 to 20 minutes per eye. I remove the stiffened natural lens through a tiny incision and replace it with an intraocular lens (IOL) chosen for your anatomy and your life. Most patients are back to normal activities within a few days. Because the natural lens is gone, it cannot cloud into a cataract later.

For a post-LASIK patient, though, there is one important wrinkle, and it is the reason this decision deserves an experienced lens surgeon.

The post-LASIK catch: your lens menu is shorter, and one lens fits it best

LASIK permanently changed the curvature of your cornea, and corneal curvature is one of the two numbers every lens-power calculation depends on. Standard formulas assume a cornea that was never lasered. Plug in a post-LASIK cornea and the math can miss, which is why a post-LASIK patient at a less experienced practice sometimes wakes up from lens surgery unexpectedly farsighted.

The second issue is optics. A laser-shaped cornea scatters light a little differently than an untouched one. The trifocal lenses that give the highest rates of glasses independence depend on a smooth, predictable cornea to work. On a post-LASIK cornea they can amplify glare and halos instead. That is why patients with prior LASIK are typically limited to a monofocal lens or the Light Adjustable Lens™ (LAL), and why I do not usually offer a trifocal in these eyes. That is not a limitation of the practice; it is honest counseling. I cover the full post-LASIK lens menu in Cataract Surgery After LASIK.

The good news is that one lens was practically designed for this problem. The Light Adjustable Lens is the only IOL whose power can be customized after surgery. I implant it, you heal, you test-drive your vision in real life, and then I fine-tune the lens with a series of painless light treatments and lock it in. If the calculation was off by a small amount because of your old LASIK, the lens is adjusted to your actual result rather than a prediction. It also lets patients trial mini-monovision safely before committing.

Our Light Adjustable Lens results

In our 2025 series of 137 eyes, 98% finished within 0.50 diopters of target and 91% saw 20/20 or better. Individual results vary. In the FDA clinical study, LAL patients were twice as likely to achieve 20/20 distance vision at six months without glasses compared with a standard monofocal. More than 300,000 have been implanted worldwide (RxSight, 2026). Full data at our LAL results page.

For the rare post-LASIK eye with a significantly irregular cornea, the Apthera™ IOL, a small-aperture lens, is the reserved alternative. And a high-quality monofocal or toric monofocal remains a strong choice for patients who value the crispest possible distance vision and are happy to use readers.

Who this is NOT for

I say no to RLE more often than people expect, and post-LASIK patients deserve the same candor.

If you are in your early 40s with a stable prescription and a lens that still scores well on the iTrace, you may not need lens surgery yet, and a LASIK enhancement could still be the right call. If your eye has significant dry eye, retinal disease, or a cornea that scans as irregular, the conversation changes. And if you still have a fair amount of natural focusing ability, replacing the lens would take that away, so I would rather wait.

Risk deserves a plain statement, too. RLE carries the same rare but serious risks as cataract surgery. Retinal detachment is the one I discuss most: roughly 1 in 500 for RLE versus 1 in 1,000 for cataract surgery (Passaro et al., British Journal of Ophthalmology, 2025). That difference is not because RLE is a riskier operation. It is the same surgery. The difference is the patient: RLE patients are younger, so the vitreous gel is more often still attached to the retina, and lens surgery tends to bring on its separation sooner, which is the event that can tear a retina. RLE patients are also more often highly nearsighted, with longer eyes and thinner peripheral retina. Older cataract patients have usually already passed through that separation safely. If you were a high myope before LASIK, I will examine your retina carefully and may send you to a retina colleague before we decide anything.

Why experience matters here

I have performed LASIK since 1998 and lens surgery in Newport Beach since founding Feinerman Vision in 2001, so I have planned and performed lens surgery on a great many eyes that had LASIK first, including my own patients from decades ago. I was the first surgeon in Southern California to implant a premium IOL after FDA approval in 2003, and I have served as principal investigator in FDA clinical trials of new lens technology. For post-LASIK eyes, I measure the cornea on three separate devices and cross-check them before any lens is ordered. I perform every evaluation and every surgery myself, call you the evening of surgery, and ask you to save my cell number so you can reach me directly.

What I tell my 1998 patients who think their LASIK wore off

You made a good decision with the best technology of its time, and it worked. The cornea I treated is still doing what it was built to do. What changed is the lens behind it, on the same schedule it changes for everyone.

The difference now is that you have a lens-based option that did not exist in a mature form 25 years ago, and a lens that can be adjusted after surgery to account for the cornea we shaped back then. The right next step is not another laser. It is a measurement, and an honest conversation about what your lens is doing and what you want your vision to do for the next 30 years.

Frequently asked questions

Does LASIK wear off after 20 years?

No. The corneal reshaping from LASIK is permanent. What changes after 20 years is the natural lens inside the eye, which stiffens and loses clarity with age in every eye. That change produces the reading difficulty and dimming that patients mistake for LASIK wearing off.

Can I get LASIK again if my vision changed?

Sometimes, if you are in your early 40s with a stable prescription and enough corneal thickness. Over 45, I generally do not recommend LASIK, because the aging lens is usually the real problem, and more laser does not fix the lens.

What is refractive lens exchange after LASIK?

Refractive lens exchange (RLE) replaces the aging natural lens with an intraocular lens before a cataract forms. It is the same procedure as cataract surgery, performed earlier. In post-LASIK eyes, lens choice is usually a monofocal or the Light Adjustable Lens, because the laser-altered cornea makes standard calculations less predictable and trifocals less reliable.

Why is the Light Adjustable Lens recommended after LASIK?

Because it is the only lens whose power can be fine-tuned after surgery. Prior LASIK makes lens-power calculations less predictable; adjustability solves the problem the old cornea creates, since the lens is adjusted to your actual result rather than a prediction.

Will I get cataracts after RLE?

No. RLE removes the natural lens, and only the natural lens can develop a cataract. The artificial lens does not cloud. Some patients later need a brief in-office laser to clear a membrane behind the lens, which is routine.

How do I know if it is my LASIK or my lens?

An evaluation with ray-tracing aberrometry measures the cornea and lens separately and scores the lens’s optical quality. If the cornea is still crisp and the lens score has dropped, the lens is the problem.
