LASIK for farsightedness and reading

You might already know that laser eye surgery can fix nearsightedness, but can LASIK also fix farsightedness?

Yes, LASIK can correct farsightedness for patients who qualify for the procedure. The correction is often permanent and usually doesn’t require additional follow-up procedures.

In the past, farsightedness could only be treated by wearing glasses or contact lenses. Both solutions are still widely prescribed, but laser eye surgeries now offer an alternative for people who want to avoid the hassle of glasses or contacts.

If you qualify, a brief LASIK operation can be a lifelong solution to this common condition.

Farsighted vision vs. nearsighted vision

If you’re farsighted, distant objects appear most clearly while close-up objects are blurry and difficult to focus on.

For nearsighted people, the opposite is true. They might be able to read a book without glasses, but making out a distant street sign seems almost impossible.

You may hear eye doctors refer to farsightedness by its medical name, hyperopia. It isn’t nearly as common as nearsightedness (myopia), but farsightedness is still considered common. About 5% to 10% of Americans are farsighted, according to the National Eye Institute.

Farsightedness occurs when the shape of the eye is slightly shorter from front to back, compared to a normal eye. This causes light to focus past the back of the eye (the retina), making near objects look fuzzy.

You can’t be nearsighted and farsighted at the same time, at least not in the same eye. It is possible, however, to be farsighted in one eye and nearsighted in the other — but that’s rare.

If you have blurry vision at both near and far distances, the odds are that you have astigmatism, which can also be corrected by LASIK (or corrective lenses).

How LASIK treats farsightedness

A farsighted LASIK patient goes through roughly the same process as a patient with nearsightedness or astigmatism.

During a LASIK procedure, a patient’s eyes are numbed with anesthetic eye drops before a flap of tissue is pulled back, giving the surgeon access to the cornea. Once the cornea is accessible, an ultra-precise laser changes the cornea’s surface. Don’t worry — this laser shuts off automatically if there’s any eye movement.

Finally, the surgeon puts the tissue flap back in its original place, where it heals mostly within the next few hours.

LASIK eye surgery for farsightedness may not be suitable for people with high levels of hyperopia, thin corneas or other health considerations. If you find out you’re not a good candidate for LASIK, you may still qualify for PRK, implantable lenses or other forms of laser eye surgery.

Can LASIK correct presbyopia?

If you’re over 40 and struggle to read small print even while wearing glasses or contacts, you might have presbyopia, a natural part of the aging process that affects your near vision.

People with presbyopia often find they need to hold reading material at arm’s length to see it clearly. For those who qualify, LASIK and other types of surgery can treat presbyopia symptoms. Here are a few of the methods typically used:

  • Modern LASIK for reading can correct vision problems caused by presbyopia with a technique called monovision LASIK, where an eye surgeon fully corrects the vision in one eye and intentionally leaves the other eye a little nearsighted. The corrected eye will then see distant objects very clearly, while the nearsighted eye provides sharper near vision without corrective lenses. That might sound strange at first, but the human brain is very good at adapting to changes like this.

  • Another eye surgery for reading is multifocal LASIK, which reshapes the surface of the eye (the cornea) to loosely resemble a multifocal eyeglass lens. This procedure comes with a higher risk of later experiencing glare and halos, which can be difficult to reverse.

  • Corneal inlays also reduce the need for corrective lenses, but only for people with farsightedness caused by presbyopia. During this procedure, a laser is used to create a small pocket in the middle of one eye’s cornea. A tiny optical device — called a corneal inlay or corneal implant — is then placed in this pocket, which eventually seals back up by itself.

Can LASIK reduce the need for reading glasses?

If you’re a candidate for LASIK, yes.

Readers can be useful for farsighted people who don’t have presbyopia, and for people as they age and the effects of presbyopia set in.

When farsightedness or presbyopia is physically corrected with a LASIK procedure, the need for reading glasses can be drastically reduced or eliminated altogether.

An eye surgeon or ophthalmologist will be happy to answer any questions you have about LASIK or other forms of corrective eye surgery.

After a brief eye exam, they can help you decide if laser eye surgery is right for you, based on your personal preferences, vision prescription and any relevant health conditions.
