Why Might I Need Glasses After LASIK?

The whole point of LASIK surgery is to remove the need for glasses, right?

LASIK surgery permanently corrects vision problems like myopia (nearsightedness) and astigmatism, usually eliminating the need for glasses or contact lenses immediately after the procedure.

What many don’t realize is that LASIK surgery doesn’t protect against presbyopia — age-related farsightedness — which usually develops between the ages of 40 and 50.

For this reason, even individuals who have had successful LASIK surgery may need reading glasses once they become farsighted.

What is Presbyopia?

Presbyopia is a condition where the interior focusing lens thickens and loses elasticity. Less elasticity makes it more difficult for the lens to focus light on the retina, so the point of focus falls behind the retina. This makes close-up objects like books and computer screens appear blurry.

Presbyopia is a perfectly natural — if somewhat frustrating — part of the aging process. Unlike hyperopia (standard farsightedness), presbyopia is related to aging.

Since LASIK is generally performed on patients 20-30 years old, most will still experience presbyopia when they reach age 40-50, and will most likely need reading or computer glasses at that time.

What is LASIK?

LASIK is a laser eye surgery that corrects vision in people who are nearsighted or farsighted, or have astigmatism.

LASIK can correct three refractive errors:

  1. Astigmatism – caused by an imperfect shape in the cornea of your eye.
  2. Farsightedness (hyperopia) – vision is clear for objects far away but blurry for objects that are close.
  3. Nearsightedness (myopia) – vision is sharp when looking at something close, but blurred when they are far away.

Benefits of LASIK Surgery

There are many benefits to getting LASIK, including:

  • Improved vision
  • Convenience
  • Long-lasting results
  • Quick results and recovery

Can Lasik Correct Astigmatism?

The “perfect” eyeball would be a smooth sphere with optical lenses that function at their best. But in the real world, this rarely happens. Usually, eyes are not shaped perfectly and visual acuity is therefore compromised. When you have astigmatism, the eye is elliptical – similar to a football shape. As a result of this asymmetry, light rays traveling through it scatter, and vision is blurred.

Astigmatism is a common vision condition. By definition, it is simply a refractive error like nearsightedness and farsightedness. Just like those vision conditions, astigmatism can be corrected with prescription eyeglasses, contact lenses and LASIK. At our eye care clinic, we perform comprehensive eye exams to determine your candidacy for laser surgery. Book a consultation with our optometrist about LASIK.

How can LASIK help?

If you have only a mild astigmatism, laser correction surgery may not be required. But if astigmatism is disturbing your vision, LASIK can be an option.

During this procedure, your eye surgeon will use a laser to reshape your cornea so it is more spherical and can focus light properly. LASIK thereby improves vision across your entire visual field, and not just the part of your view affected by prescription eyewear.

How successful is LASIK for correcting astigmatism?

LASIK for astigmatism can be an excellent solution when compared to alternatives, such as glasses or contact lenses. That’s because eyeglasses and contacts work by cancelling out the visual distortion, whereas LASIK totally changes and corrects the irregularity in your cornea. For many people, the procedure is transformative to their lives.

The success rate of LASIK for astigmatism is associated strongly with the vision prescription of the patient and the unique shape of the eye. Official reports state that LASIK is most suitable for people with a prescription of up to four cylinders of astigmatism. Also, if you only have a tiny amount of astigmatism, such as 0.5 diopter, LASIK may not provide a significant benefit. Therefore, the success rate of LASIK for astigmatism varies, which is why you need an experienced eye doctor to assess your eyes and vision to determine your candidacy.

Our LASIK optometrists offer specialized consultations and eye exams.

Is LASIK affordable?

Even if you have an extreme vision prescription, LASIK is still regarded as an elective treatment by most insurance policies, so it isn’t covered by their basic plans. However, significant savings are frequently offered by various insurance plans. Our staff is knowledgeable about ways to make LASIK affordable, and we’re happy to share the info!
