LASIK Age Limits: How Young and How Old Is Too Much?
What is the minimum age for LASIK?
The minimum is 18, the age for which LASIK lasers are FDA-approved, though most surgeons prefer to wait until the early to mid-20s.
Nearsightedness often keeps progressing through the teens and early twenties. Treating an eye that is still changing can mean glasses again within a few years. The FDA lists a prescription that changed within the last year as a reason you may not be a good candidate. Korean clinics generally follow the same principle.
LASIK suitability by age group
Age is only one factor; your exam outweighs it.
| Age | Typical situation | Options often discussed |
|---|---|---|
| Under 18 | Eyes still developing | Glasses or contacts; wait |
| 18–24 | Prescription may still be changing | LASIK, SMILE or PRK if stable for 12+ months |
| 25–39 | Most stable, often ideal | LASIK, SMILE, PRK/LASEK, ICL for high myopia |
| 40–49 | Presbyopia begins | LASIK with monovision, SMILE, ICL (EVO ICL label now to 60) |
| 50–59 | Presbyopia established, lens changes possible | Monovision laser, refractive lens exchange |
| 60+ | Cataract increasingly common | Cataract surgery or lens exchange, multifocal IOLs |
Why does prescription stability matter more than age?
Because laser surgery corrects the prescription you have today; if your eyes are still changing, the result will drift.
The FDA's benchmark is no change in the past year, and the US EVO ICL label likewise requires refraction stable within 0.5 D for a year before implantation. Some clinics ask for a longer record; one US provider notes that a stable prescription for at least two years is often required. That is why a 23-year-old with a changing prescription may be told to wait, while a 19-year-old with several years of identical records may be considered. Bring copies of past prescriptions to your consultation to make the case clearly.
Is there a maximum age for LASIK?
No fixed maximum exists. A healthy 65-year-old with clear lenses may be a better candidate than a 30-year-old with severe dry eye.
What changes with age is the rest of the eye. Dry eye becomes more common, and cataract risk rises from around 60. If a cataract is starting, LASIK would correct a lens that will soon be replaced, so cataract surgery in Korea may make more sense.
What happens after 40?
From the 40s, presbyopia makes close focus harder, and LASIK does not cure it.
Distance-corrected LASIK at 45 will usually leave you needing reading glasses. Some patients choose monovision, where one eye is set for distance and the other slightly for near; a contact lens trial first is wise. See presbyopia treatment in Korea.
Is monovision a good idea?
Monovision suits some people over 40 well and others not at all, which is why a trial first matters.
With monovision, your brain learns to use one eye for distance and the other for near. Many people adapt within weeks, but depth perception and night driving can feel different, and some never get comfortable. Wearing monovision contact lenses for a period before surgery lets you test it at low risk. If it does not suit you, distance correction plus reading glasses, or a lens-based option later, may be better. Ask your surgeon how much near correction they would plan and whether it can be adjusted.
Can I get ICL or SMILE at an older age?
Yes, within limits. In 2026 the FDA expanded the EVO and EVO+ Visian ICL age indication from 21–45 to 21–60.
SMILE has no special age cut-off beyond general candidacy. Over 50, lens exchange with a multifocal IOL may address distance and near together, and avoids a future cataract. Compare in ICL vs LASIK.
Does age affect LASIK risks?
Somewhat, in both directions.
Young age is a recognised risk factor for ectasia: the Randleman score treats patients under 22 as at least moderate risk, though some experts dispute the weighting. Older patients more often have dry eye and slower healing. A thorough exam, including corneal tomography and tear testing, matters at every age.
What can I do if I'm too young right now?
Use the waiting time to build the evidence a surgeon will want to see.
Because the key test is a stable prescription, have an eye exam each year and keep copies of every prescription. When you book a consultation, those records help show whether your eyes have stopped changing over the last 12 months or more. Keep contact lens wear healthy, since corneal problems from overwear can delay surgery. If you are close to 18 and your prescription is still shifting, the most useful step is simply to wait: treatment on a changing eye risks needing glasses again within a few years.

What do age-appropriate options cost in Seoul?
The right procedure often changes with age, and so does the price.
| Procedure | Typical age group | Seoul price (2026) |
|---|---|---|
| LASIK | Stable adults, often 20s–40s | ₩1.5M–₩2.5M both eyes (≈$1,100–$1,900) |
| SMILE | Stable adults, often 20s–40s | ₩2.2M–₩3.2M both eyes (≈$1,600–$2,400) |
| PRK | Stable adults with thinner corneas | ₩1.3M–₩2.2M both eyes (≈$950–$1,650) |
| ICL | High myopia; US label 21–60 | ₩4M–₩6.5M both eyes (≈$2,900–$4,700) |
| Cataract surgery | Usually 60+ | ₩1.5M–₩7.5M per eye, depending on lens |
USD figures are approximate at ₩1,350–1,400 per dollar. For lens-based options after 50, see presbyopia surgery cost and cataract surgery cost in Korea.
How do I know what's right for my age?
Book a full pre-op exam and ask the surgeon to explain each option for your age and eyes.

FAQ
Frequently asked questions
Can I get LASIK at 18?
Technically yes, as lasers are FDA-approved from 18, but many surgeons advise waiting until your prescription has been stable for at least a year, often into your 20s.
What is the best age for LASIK?
Many surgeons consider the mid-20s to late 30s ideal, because prescriptions are usually stable and presbyopia has not yet started.
Is 50 too old for LASIK?
Not automatically. Healthy eyes at 50 can be treated, but you will likely still need reading glasses unless you choose monovision, and lens exchange may be worth comparing.
Can a 60-year-old get LASIK?
Sometimes, if there is no cataract and the cornea is healthy. Many people over 60 are better served by cataract surgery or lens exchange.
Will my eyes get worse again after LASIK?
LASIK's correction is permanent, but your eyes keep ageing. Presbyopia and cataract can still develop, and a small number of patients need an enhancement.
