Can LASIK Correct Nearsightedness and Farsightedness at the Same Time?

Can LASIK Correct Nearsightedness and Farsightedness at the Same Time

Verified Reviews

LASIK, a popular laser eye surgery, is widely known for correcting vision issues. But can it correct both nearsightedness (myopia) and farsightedness (hyperopia) simultaneously? The short answer is yes. Through advanced techniques like Monovision LASIK and Presby-LASIK, it is possible to address both conditions, providing clearer vision for people who struggle with seeing objects both near and far.

Understanding Nearsightedness and Farsightedness

Nearsightedness (Myopia):

  • Difficulty seeing distant objects clearly.
  • Light focuses in front of the retina due to a longer-than-normal eyeball or overly curved cornea.

Farsightedness (Hyperopia):

  • Difficulty seeing close objects clearly.
  • Light focuses behind the retina because the eyeball is shorter than normal or the cornea is too flat.

How LASIK Works

LASIK works by reshaping the cornea, the clear front part of the eye, to ensure light focuses directly on the retina. For nearsightedness, the cornea is flattened, while for farsightedness, it is steepened.

LASIK for Nearsightedness

Nearsighted individuals have corneas that are too curved. LASIK flattens the cornea, allowing light to focus correctly on the retina, improving distant vision.

LASIK for Farsightedness

For farsighted individuals, LASIK surgery steepens the cornea to bring the focus point closer to the retina, which enhances near vision.

Monovision LASIK

Monovision LASIK is a specialized technique where one eye is corrected for distance vision and the other for near vision. This is often referred to as “blended vision”. The brain learns to use both eyes together, merging the two fields of vision. This approach is particularly beneficial for those over 40, who may experience age-related vision changes.

How Monovision LASIK Works

  1. Assessment: The surgeon determines the dominant eye (typically used for distance vision) and the non-dominant eye (for near vision).
  2. Trial with lenses: Patients often try monovision lenses before surgery to ensure they can adapt.
  3. Surgery: The LASIK procedure is performed, correcting one eye for distance and the other for near vision.

Benefits of Monovision LASIK

  • Reduces the need for reading glasses.
  • Allows clear vision at both near and far distances.
  • Adaptable for most patients, with a high satisfaction rate.

Adjusting to Monovision LASIK

  • The brain needs time to adjust, which can take a few weeks to a few months.
  • Temporary discomfort and adaptation issues are common but usually resolve.

Monovision LASIK Pros and Cons

Reduces dependence on glasses/contactsInitial adjustment period required
Clear vision at multiple distancesNot suitable for everyone
High patient satisfactionSome may still need glasses for specific tasks
Enhances quality of lifeTemporary side effects like dry eyes

Suitability for LASIK

Not everyone is a candidate for LASIK. A thorough assessment by an experienced surgeon is crucial. Factors considered include:

  • Corneal thickness
  • Overall eye health
  • Stability of vision
  • Absence of certain conditions (e.g., severe dry eye, keratoconus)

Who Should Avoid LASIK?

  • Individuals under 20 (vision still changing)
  • Pregnant or breastfeeding women
  • Those with unstable vision prescriptions
  • Patients with certain health conditions (e.g., autoimmune diseases)

Benefits and Risks


  • Improved vision without glasses or contacts.
  • Quick recovery time.
  • High satisfaction rates among patients.


  • Temporary dry eyes
  • Glare and halos around lights
  • Potential for under or over-correction
  • Rare complications like infection or vision changes

Frequently Asked Questions

Can LASIK Correct Both Nearsightedness and Farsightedness?

Yes, through techniques like Presby-LASIK and Monovision LASIK, where one eye is corrected for distance and the other for near vision. This allows clear sight at varying distances.

How Long Does It Take to Adjust to Monovision LASIK?

Adjustment can take a few weeks to a few months. The brain needs time to adapt to using each eye for different distances.

What Are the Side Effects of Monovision LASIK?

Common side effects include:

  • Temporary dry eyes
  • Glare or halos around lights
  • Initial difficulty in adjusting to the new vision pattern

Is Monovision LASIK Suitable for Everyone?

Not everyone adapts well to Monovision LASIK. It’s recommended to try monovision contact lenses first. Those who adjust well are good candidates for the surgery.


LASIK can effectively correct both nearsightedness and farsightedness, offering significant improvements in vision and quality of life. Whether considering monovision LASIK or full-distance correction, a thorough evaluation by a qualified surgeon at Liberty Laser Eye Center can determine the best approach for your specific needs.
