LASIK is a permanent laser surgery on the surface of the eyes to reduce the need for corrective lenses.
LASIK can correct distance vision problems and some astigmatism.
Beyond the age of 40, if both eyes have been corrected for distance with LASIK, it’s likely you’ll need reading glasses to see clearly up close.
Once people reach their 40s, most begin to experience presbyopia — otherwise known as difficulty focusing up close. If both eyes have been treated for distance at the time of LASIK, reading glasses are usually needed at or around age 40 to help with close vision.
LASIK is a refractive surgery that involves removing part of the tissue of the cornea to reduce or remove the need for glasses.
LASIK is designed to be permanent, meaning as long as the shape of the eye stays the same, the effect will be lasting. A small number of people experience shifts or changes in their prescriptions after LASIK, and these can often be corrected with a second round of treatment. Unfortunately, LASIK does not prevent other eye conditions like presbyopia or cataracts, so if these happen later in life, they usually require separate treatment.
Most people under 40 will not need glasses to see their best at distance after LASIK. But, as presbyopia often develops around the age of 40 and beyond, it is common to start needing reading glasses to see well up close. If both eyes are corrected for distance with LASIK, then reading glasses or a single reading contact lens will be needed if presbyopia sets in. If only the dominant eye was corrected for distance (monovision), then reading glasses may not be needed.
LASIK does not make presbyopia worse. But people with nearsightedness (myopia) who do not get LASIK are often able to avoid the need for reading glasses by removing their distance glasses to read.
If you are concerned that your LASIK-corrected vision is worsening, an eye exam will help to determine the cause. If you are developing shifts in your distance prescription, repeat LASIK may be able to help. Reading glasses or a monovision contact can help if presbyopia has started. Cataract surgeryCataract surgery is likely to restore your vision if cataracts have formed.
LASIK surgery is a safe and effective treatment to get rid of or lessen the need for distance glasses. Most of the time, the improvement is permanent. If the prescription shifts after LASIK, then LASIK can usually be repeated. Still, LASIK will not prevent other conditions like presbyopia and cataracts from affecting your vision. And, after age 40, reading glasses are often helpful for focusing up close. A monovision contact is one alternative to reading glasses.
