If you are nearsighted, you are in very good company — and you are also looking at the single most common reason people get LASIK in the first place. Nearsightedness, or myopia, is exactly what laser vision correction was first designed to treat, and it remains the condition LASIK handles best. So the short answer to “can you get LASIK for nearsightedness?” is a confident yes, for most people.
This guide from Visual Aids Centre explains how LASIK corrects myopia, how much nearsightedness it can treat, who makes a good candidate, and what the options are if your prescription is very high — so you can see exactly where you stand.
Key Takeaways
- LASIK is highly effective for nearsightedness — it is the condition the procedure treats best.
- It works by gently flattening the cornea so light focuses correctly on the retina.
- LASIK can treat a wide range of myopia, with very high prescriptions assessed case by case.
- Thin corneas or extreme myopia may be better suited to SMILE or an ICL.
- A corneal assessment confirms whether LASIK is the right fit for your degree of myopia.
How LASIK Corrects Nearsightedness
Nearsightedness happens when your eye is slightly too long, or your cornea too steeply curved, so light focuses just in front of the retina instead of on it. That is why distant objects look blurry while near ones stay clear.
LASIK fixes this elegantly: the laser gently flattens the central cornea, moving the focal point back onto the retina where it belongs. The result is clear distance vision without glasses. It is a precise, well-established correction — our guide on whether LASIK can fix short-sightedness walks through the mechanism, and because LASIK also treats farsightedness, you can see how it corrects both long and short sight.
How Much Myopia Can LASIK Treat?
LASIK treats a broad range of nearsightedness — from very mild to fairly high prescriptions. The exact ceiling depends on your individual cornea, because correcting more myopia means removing more tissue, and there must be enough healthy cornea left afterwards.
This is why there is a practical limit rather than a single universal number. Our detailed look at how much myopia LASIK can correct and the myopia power limit for LASIK explain how surgeons weigh prescription against corneal thickness to keep your correction safe.
Are You a Good Candidate?
Beyond the degree of myopia itself, a few familiar factors decide candidacy:
- A stable prescription — your nearsightedness should not have changed much in the past year.
- Adequate corneal thickness to allow safe reshaping.
- Healthy eyes free of conditions that affect healing.
- Being 18 or older, since myopia often progresses through the teens.
If you have a strong prescription, it is worth knowing that LASIK can still be excellent for high myopia in the right eyes — the assessment is what confirms it.
Options for Very High Myopia
If your nearsightedness is extreme, or your corneas are too thin for the amount of correction needed, LASIK may not be the safest choice — but that rarely means you are out of options. Two alternatives shine here:
- SMILE Pro: a flapless laser procedure that preserves more corneal strength, often suited to higher myopia.
- ICL: an implantable lens that corrects very high prescriptions without removing corneal tissue at all.
There is also a rarer, more serious form called degenerative (pathological) myopia, which needs specialist evaluation, since it involves more than a simple refractive error.
What to Expect From the Results
For nearsighted patients, LASIK results are often genuinely life-changing — most achieve 20/20 or better and wake the morning after surgery able to see across the room unaided. Recovery is fast, and the correction is permanent for a stable prescription.
Conclusion
Can you get LASIK for nearsightedness? For most people, absolutely — myopia is precisely what LASIK does best, correcting it by reshaping the cornea so distance vision becomes clear and glasses-free. It treats a wide range of prescriptions, with very high myopia or thin corneas pointing toward excellent alternatives like SMILE Pro or an ICL. The only way to know your exact fit is a corneal assessment that measures your prescription against your eye’s anatomy.

Frequently Asked Questions (FAQs)
Can LASIK fix nearsightedness?
Yes. Nearsightedness (myopia) is the condition LASIK treats best. The laser flattens the cornea so light focuses on the retina, giving clear distance vision.
How much nearsightedness can LASIK correct?
A wide range, from mild to fairly high. The limit depends on your corneal thickness, since higher corrections remove more tissue. An assessment confirms your range.
What if my myopia is too high for LASIK?
SMILE Pro or an ICL are often excellent alternatives for very high prescriptions or thin corneas, correcting vision safely without the limits LASIK faces.
Is LASIK for myopia permanent?
Yes, the correction is permanent for a stable prescription, though natural ageing can still affect near vision later in life.
At what age can I get LASIK for nearsightedness?
Usually from 18, once your myopia has stabilised. Treating eyes that are still changing risks the prescription shifting after surgery.
Will I still need glasses after LASIK for myopia?
Most people achieve clear distance vision without glasses. Reading glasses may be needed later in life due to normal age-related changes.
