In general, LASIK is considered to be a safe procedure for adults of all ages. The U.S. Food and Drug Administration (FDA) publishes that you need to be at least 18 years old in order to qualify for LASIK. (Learn More) In general, the average age at which people undergo a LASIK procedure is between the ages of 20 and 40. (Learn More)
There is no specific age that is considered too old for the surgery, but certain considerations and recommendations need to be explored in the older population.

How Old Must You Be to Get LASIK? (Minimum)
How old you are is a significant factor in deciding whether or not to get LASIK. LASIK surgery is not FDA-approved for anyone under the age of 18 except in very rare cases where a child may be extremely nearsighted in only one eye. The U.S. National Library of Medicine (NLM) publishes that the use of some lasers is only approved for people aged 21 and older.
Refractive errors, such as myopia (nearsightedness), can continue to evolve up until your mid-20s, the Federal Trade Commission (FTC) explains, so it is actually better to wait until at least then in order to for your eyes to be done growing, maturing, and changing.
LASIK surgery involves altering the shape of the cornea to correct a refractive error in order to sharpen the images focused on the retina using an excimer laser. In this way, things such as farsightedness and nearsightedness (when images are blurry either far away or close up) can be corrected. Astigmatism, a misshapen cornea, can also be corrected through LASIK surgery.
Typical (Recommended) Age Range for LASIK
As your eyes typically stabilize by age 20 (or sometimes a few years into your 20s), and they may change again at age 40, the typical age range for a LASIK procedure is between age 20 and 40. This is generally considered to be the ideal and recommended age range.
Before age 20, your eye prescription is often not done changing. Nearsightedness in particular can continue to worsen.
After age 40, people can develop presbyopia. Presbyopia is also called "aging eyes" and can occur any time after age 35, the National Eye Institute publishes. Presbyopia occurs when you struggle to see things clearly up close, often requiring the use of reading glasses. As you age, the lenses in your eyes harden, and the small muscles are unable to contract the less flexible lenses for a sharper image as they can when the lenses are more pliable and softer in younger eyes.
Presbyopia often occurs simultaneously with other refractive errors, such as farsightedness (hyperopia), nearsightedness (myopia), and astigmatism. Presbyopia cannot be directly corrected with LASIK surgery, but a procedure called monovision can be a consideration. Monovision corrects each eye separately. One eye is corrected for nearsightedness, and the other for farsightedness. You will need an adjustment period to get used to this. It may not be suited for everyone, as it can take some getting used to.
Eye Stability and Age Considerations for LASIK
In order to be eligible for LASIK surgery, your eye prescription needs to be stable for at least a year. This means your eyesight needs to have been unchanged for at least a year — and sometimes two — in order to ensure that the correction is ideal and will not require another surgery in the near future.
The FTC reports that about 10 percent of Americans who undergo LASIK will need retreatment, or a second surgery, down the line in order to maintain the vision correction the procedure initiated. This is especially true if the refractive error being corrected is significant. LASIK corrects for a certain range of prescriptions, and your ophthalmologist can ensure that your eyesight falls into the correctible range.
Pregnancy can impact the stability and measured refraction in your eyes. After having a baby, you should wait until you are done breastfeeding before considering LASIK.
Certain medications, such as steroids, can impact eye health and measurements. They should be stopped for a period of time before screening for a LASIK procedure.
General health must be good for LASIK to be a consideration. This means both eye health and the rest of the body. LASIK is a surgical procedure, and your body needs to be able to heal itself properly after the procedure.
To establish your candidacy for LASIK, the initial assessment will include a baseline evaluation to determine what level of correction is needed, the FDA explains. In order to come up with an accurate baseline, you will need to stop wearing contacts for a few weeks, so your corneas can return to their normal shape. This ensures an accurate evaluation that can lead to the best possible surgical results and vision improvements.
Age Cap for LASIK
You can hardly ever be considered too old for LASIK surgery, but there are certain considerations that need to be explored as you age. There are several age-related conditions that can impact the eye and therefore influence eligibility for LASIK surgery.
By age 60, for instance, most people will experience some level of cloudiness, or opaqueness, in their lenses. When the lens of the eye gets clouded with age, it is generally due to a cataract. About half of the population between the ages of 65 and 74 suffer from cataracts, and that number jumps to 70 percent by age 75. LASIK surgery does not correct or prevent cataracts.
If your eyes show any signs of a cataract, it may be recommended to wait until they are formed and then have a specialized cataract surgery that can take out the clouded lens and replace it with an artificial implant, clearing your vision. If you have LASIK before developing cataracts, you are likely to need another surgery. LASIK can make the cataract implant surgery more complicated.
Glaucoma and dry eyes are also conditions that often affect older eyes and can impact eligibility for LASIK. Glaucoma occurs when fluid builds up in the eye and presses on the optic nerve. This pressure can increase during a LASIK procedure, so if you suffer from significant glaucoma, LASIK is typically inadvisable, but if the condition is mild, you may still be a candidate.
LASIK surgery involves creating a corneal flap in the outer layer of the cornea, ablating the inner tissue, and then replacing the flap. This procedure can decrease your tear production and therefore exacerbate dry eyes.
The American Refractive Surgery Council reports that dry eyes are a common side effect of LASIK surgery. Due to this, it is not recommended to get LASIK if you already suffer from extremely dry eyes. As we age, tear production decreases, and dry eyes can become worse. This is more common in women, especially following menopause, so it is something to consider before undergoing LASIK surgery. There are other laser corrective eye surgeries that may be preferable in these cases.
How to Know When It’s the Ideal Time to Get LASIK
In order to ensure that it is the right time for you to get LASIK, you can use the following set of guidelines:
- Your eyeglass or contact prescription has been stable for at least 12 months.
- You and your eyes are in good health.
- You are at least 18 but preferably in your mid-20s or older.
- You do not have any cloudiness in your eyes or suffer from cataracts, glaucoma, or excessive dry eyes.
Speak with your ophthalmologist to determine your candidacy for LASIK surgery and when the ideal time for you and your eyes might be.
