    Question

    Can scleral lenses help after LASIK?

    Most people do well after LASIK. Some are left with dry, uncomfortable eyes or vision that glasses can't sharpen. Here's when a scleral lens can help, even without ectasia.

    The short answer

    Yes, for some people. LASIK and other laser surgeries can leave the cornea's surface uneven, which causes halos, ghosting, or blur that glasses can't correct, and they can also cause dry eye. A scleral lens covers the uneven surface with a smooth optical one and bathes the cornea in fluid. In a small study of people with irregular corneas after refractive surgery, vision and dry eye symptoms both improved. If your cornea has started to bulge (ectasia), that is a different problem, covered on its own page.

    Key points

    • Cutting corneal nerves during surgery is a main driver of dry eye after LASIK.
    • Irregular astigmatism after surgery causes blur, halos and ghosting that glasses often can't fix.
    • In one study of 35 eyes, scleral lenses improved vision and dry eye scores after refractive surgery.
    • Scleral lenses manage symptoms. They don't reverse the surgery or regrow nerves.

    Two different problems after LASIK

    When people say “my eyes haven’t been right since LASIK,” they usually mean one or both of these:

    Dry eye. Dry eye frequently follows laser vision surgery. A 2024 systematic review describes the main cause as nerve damage from the surgery itself: cutting corneal nerves sets off inflammation and reduces tear production, which destabilizes the tear film. Risk factors include having LASIK rather than surface treatment (PRK), deeper treatments, and existing meibomian gland problems.[1] LASIK and PRK are also on the list of causes of neurotrophic keratopathy, the more severe condition in which the cornea loses its feeling and heals poorly.[3]

    Irregular optics. Laser surgery can leave the cornea’s surface uneven, a problem called irregular astigmatism. An uneven surface doesn’t focus light cleanly, which causes blur, halos, starbursts and ghost images. Glasses often can’t fully correct it, because they can’t follow the bumps and slopes of an uneven surface.

    If your cornea has thinned and started to bulge after surgery, that’s corneal ectasia, which is a separate condition with its own page: scleral lenses for post-LASIK ectasia.

    How a scleral lens helps

    A scleral lens vaults over the cornea and rests on the white of the eye. You fill it with sterile saline before insertion, so the cornea sits under a pool of fluid all day. That does two things:

    • The smooth front of the lens replaces the uneven surface of the cornea as the eye’s main focusing surface, which reduces the distortions behind halos and ghosting.
    • The fluid keeps the cornea wet and shields it from the drying, rubbing effect of blinking.

    Scleral lenses are used across the range of post-surgery problems: irregular astigmatism, ectasia, and dry eye.[4] More detail is on the pages for irregular astigmatism and severe dry eye.

    What the research shows

    The evidence specific to LASIK without ectasia is limited. The clearest study followed 19 people (35 eyes) with irregular corneas after refractive surgery, all fitted with scleral lenses after other contact lenses had failed.[2]

    • Vision: best corrected vision improved from 0.33 to 0.08 on the logMAR scale, where lower is sharper and 0 equals 20/20.[2]
    • Dry eye symptoms: scores on a standard questionnaire (the OSDI, where higher is worse) fell from 66.2 to 42.4.[2]
    • Optical quality: measures of light scatter and higher-order aberrations, the irregular distortions behind halos and ghosting, also fell significantly.[2]

    The authors concluded scleral lenses can be an alternative to further surgery on these eyes.[2] It was a small, single-center study, so it shows what’s possible rather than what any one person should expect. Symptoms improved on average, but they didn’t disappear.

    What to expect day to day

    Scleral lenses add a routine: inserting, removing, cleaning, and sometimes a midday refill. In a survey of people using therapeutic lenses for dry eye, 75% of scleral lens wearers reported midday fogging or clouding, and 72% spent more than 20 minutes a day on dry eye care.[5] If fogging is a problem for you, the page on blepharitis and MGD explains why the eyelids matter.

    Common questions

    Does a scleral lens press on my LASIK flap?

    A scleral lens is designed to vault over the whole cornea and rest on the white of the eye, with a layer of fluid between the lens and the cornea. Your fitter checks that clearance at your visits. If you have concerns about your flap, ask your fitter and your surgeon to look at it together.

    I had LASIK years ago and my night vision has slowly gotten worse. Is that dry eye or something else?

    It could be many things, including dry eye, a change in your prescription, a cataract, or, less commonly, the cornea starting to bulge (ectasia). Get a full exam with corneal mapping before assuming it's one cause. The right treatment depends on what's found.

    Can scleral lenses fix the dry eye from LASIK for good?

    No. A scleral lens keeps the cornea bathed in fluid while you wear it, which can ease symptoms a lot, but it doesn't treat the underlying cause. Dry eye treatment usually continues alongside the lens, guided by your eye doctor.

    Do scleral lenses correct astigmatism?

    Yes. A scleral lens vaults over the cornea on a layer of saline, which smooths out astigmatism coming from the front of the eye, including the irregular kind that glasses and soft lenses can't correct well. Some people still have a little astigmatism left over, often from inside the eye or from the lens flexing, and the fitter can build a correction for it into the front of the lens.

    Can scleral lenses fix double vision?

    If the double or ghost image is in one eye, and it's caused by an irregular cornea such as keratoconus, a scleral lens often reduces or clears it by giving the eye a smooth optical surface. If you see double only with both eyes open, because the eyes aren't lined up, a standard scleral lens won't fix that, though prism can be built into some custom lenses. Double vision that comes on suddenly needs prompt medical assessment, because some causes are serious.

    Can scleral lenses help with light sensitivity?

    Sometimes. If your light sensitivity comes from a damaged, dry, or irregular front surface of the eye, a scleral lens may reduce it by covering and bathing the cornea and by smoothing the glare and halos an irregular cornea causes. A standard scleral lens is clear, though, so it doesn't block light, and it won't help light sensitivity that comes from inside the eye, the nerves, or migraine. New light sensitivity while you're wearing scleral lenses can be a sign of a problem: remove the lens and call your eye doctor.

    Can I wear scleral lenses with blepharitis or MGD?

    Yes, most people can, but treating the eyelids is part of making the lenses work. Blepharitis and meibomian gland dysfunction (MGD) disturb the tear film over the front of the lens, which can make vision hazy a few hours into the day. Research links this front-surface fogging to poor wetting of the lens surface and to eye surface inflammation. Lid treatment, a lens surface treatment, and sometimes a planned midday clean and refill can all help.

    Can I wear scleral lenses after cataract surgery?

    Usually, yes, once your surgeon and fitter agree your eye has healed. Cataract surgery replaces the eye's natural lens, but it doesn't smooth an irregular cornea, so people with keratoconus, a corneal transplant, or other corneal irregularity often still need a specialty lens afterward. Scleral lenses are also one option for people who are left without a lens implant. Medicare Part B covers one set of contact lenses after each cataract surgery that implants a lens, with rules that are worth checking.
