LASIK can correct nearsightedness and farsightedness, but its ability to fix both simultaneously depends on individual eye conditions and treatment plans.
Understanding the Basics of Near and Far Sight
Near sight (myopia) means you see close objects clearly but struggle with distant ones. Far sight (hyperopia) is the opposite—distant objects appear sharp, but close ones blur. Both conditions occur because of how light focuses on the retina. In myopia, light focuses in front of the retina; in hyperopia, it focuses behind it.
These refractive errors affect millions worldwide, making everyday tasks like reading or driving challenging without corrective lenses. Glasses and contact lenses provide simple fixes, but many seek permanent solutions for freedom from dependency. That’s where LASIK comes into play.
What is LASIK and How Does It Work?
LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea—the eye’s clear front surface—to improve how light enters the eye. By sculpting the cornea with a precise laser, LASIK adjusts the focal point to land directly on the retina.
The procedure involves creating a thin flap in the cornea, lifting it, and then using an excimer laser to remove microscopic layers of tissue. This reshaping corrects refractive errors by altering corneal curvature.
LASIK is popular because it offers rapid visual recovery, minimal discomfort, and long-lasting results. However, not everyone qualifies, and its effectiveness varies based on individual vision issues.
Can Lasik Fix Both Near And Far Sight?
The straightforward answer is: LASIK can correct both near and far sight, but rarely in one single procedure for both eyes at once. Most people have one dominant refractive error—either myopia or hyperopia—and LASIK targets that issue specifically.
In some cases, monovision LASIK is employed to address both near and far vision by correcting one eye for distance and the other for near tasks. This technique helps people with presbyopia—the age-related loss of near vision—maintain functional eyesight at multiple distances without glasses.
However, monovision isn’t perfect for everyone; some patients experience reduced depth perception or slight visual discomfort adapting to this setup.
Monovision LASIK: How It Works
Monovision involves intentionally leaving one eye slightly nearsighted while fully correcting the other for distance vision. The brain learns to rely on each eye depending on what you’re focusing on—near or far.
This method suits those over 40 who develop presbyopia but want to avoid multifocal lenses or reading glasses. Success depends heavily on patient adaptability; trial contact lenses mimicking monovision are usually tested before surgery.
Limitations in Correcting Both Sights Simultaneously
Standard LASIK treats either myopia or hyperopia per eye but cannot fully restore perfect focus at all distances simultaneously due to how human eyes work. The cornea’s shape can only be altered so much without compromising structural integrity or visual quality.
People with astigmatism (irregular corneal curvature) may require additional corrections during LASIK to optimize results for distance vision but still might need reading glasses later in life as presbyopia progresses.
Suitability Factors Affecting LASIK Outcomes
Several elements influence whether LASIK can effectively fix both near and far sight:
- Age: Younger patients with simple myopia or hyperopia tend to achieve better outcomes.
- Degree of Refractive Error: High prescriptions may limit correction scope.
- Corneal Thickness: Thin corneas restrict how much tissue can be safely removed.
- Eye Health: Conditions like dry eyes or cataracts reduce candidacy.
- Lifestyle Needs: Jobs requiring precise depth perception might not suit monovision.
Eye surgeons conduct thorough evaluations including corneal mapping, pupil size measurement, and retinal health checks before recommending LASIK as an option.
The Role of Presbyopia in Dual Vision Correction
Presbyopia typically begins around age 40 when the eye’s natural lens loses elasticity, making near focusing difficult regardless of prior vision status. This condition complicates “fixing” both near and far sight with a single procedure like standard LASIK.
To tackle this challenge:
- Monovision LASIK, as mentioned earlier, offers a workaround by using each eye differently.
- PresbyLASIK, a newer variation, attempts multifocal corneal reshaping to provide simultaneous focus at multiple distances.
- Lens Replacement Surgery, such as Refractive Lens Exchange (RLE), swaps out the natural lens for an artificial multifocal lens that corrects all ranges.
Each approach has pros and cons regarding visual clarity, side effects like glare or halos, and patient satisfaction rates.
Comparing Monovision vs PresbyLASIK vs RLE
| Treatment Type | Main Benefit | Main Drawback |
|---|---|---|
| Monovision LASIK | Simplicity; avoids lens surgery; quick recovery | Possible depth perception issues; adjustment period required |
| PresbyLASIK | Mimics multifocal vision; no lens replacement needed | Less widespread availability; potential night vision disturbances |
| Lens Replacement (RLE) | Permanent multifocal correction; treats cataracts too | Surgical risks higher than LASIK; longer recovery time |
Deciding between these depends on individual needs, lifestyle demands, age, and ocular health status.
The Procedure Experience: What Patients Can Expect From LASIK?
Undergoing LASIK typically takes less than 30 minutes per eye. Patients receive numbing drops so there’s minimal discomfort during surgery. A suction ring stabilizes the eye while a microkeratome blade or femtosecond laser creates the corneal flap.
The excimer laser then sculpts the underlying tissue according to pre-programmed measurements tailored to your prescription. After reshaping, the flap is repositioned naturally without stitches.
Postoperative recovery is swift—most notice improved vision within 24 hours. Mild irritation or dryness occurs initially but resolves quickly with prescribed drops.
The Recovery Timeline in Detail
- Day 1-3: Vision fluctuates; avoid rubbing eyes; use lubricating drops frequently.
- Week 1: Most resume normal activities; follow-up visits monitor healing progress.
- Month 1-3: Vision stabilizes fully; any residual refractive error may be addressed with enhancements if necessary.
Strict adherence to post-op instructions ensures optimal outcomes and minimizes complications like infection or flap displacement.
The Risks and Considerations Before Opting For LASIK To Fix Both Near And Far Sight?
While generally safe and effective, LASIK carries risks like any surgical procedure:
- Dry Eyes: Temporary or chronic dryness due to nerve disruption during flap creation.
- Visual Disturbances: Glare, halos around lights especially at night.
- Undercorrection/Overcorrection: Might require enhancement surgery later.
- Ectasia: Rare thinning/bulging of cornea if too much tissue removed.
- Lack of Perfect Vision: Some patients still need glasses for specific tasks post-LASIK.
A detailed consultation with an experienced ophthalmologist helps weigh benefits against risks based on your unique eyes.
The Cost Factor: Is Correcting Both Near And Far Sight With LASIK Worth It?
Costs vary widely depending on location, surgeon expertise, technology used (e.g., bladeless femtosecond lasers), and whether monovision techniques are applied.
| Treatment Type | Average Cost Range (USD) | Treatment Scope Covered |
|---|---|---|
| LASEK/PRK (Surface Laser) | $1,500 – $3,000 per eye | Mild-moderate myopia/hyperopia correction |
| LASIK (Standard) | $2,000 – $4,000 per eye | Mild-moderate myopia/hyperopia/astigmatism |
| LASIK Monovision Upgrade | $500 – $1,000 additional | Adds presbyopic correction by adjusting one eye |
| LENS Replacement Surgery (RLE) | $4,000 – $6,000 per eye | Cataract + presbyopic correction |
Though upfront costs seem high compared to glasses or contacts yearly expenses add up over time—and many find freedom from constant eyewear worth every penny.

Frequently Asked Questions
Can Lasik Fix Both Near And Far Sight in One Procedure?
LASIK can correct both near and far sight, but usually not simultaneously in a single procedure for both eyes. Treatment is often tailored to address the dominant vision problem, either nearsightedness or farsightedness, rather than both at once.
How Does Lasik Fix Both Near And Far Sight with Monovision?
Monovision LASIK corrects one eye for distance vision and the other for near tasks. This approach helps people manage both near and far sight, especially those with presbyopia, by allowing the brain to switch focus between eyes depending on the task.
Is Monovision Lasik Effective for Fixing Both Near And Far Sight?
Monovision LASIK can be effective for fixing both near and far sight, but it’s not suitable for everyone. Some patients may experience reduced depth perception or difficulty adapting to the difference in vision between their eyes.
What Are the Limitations of Lasik in Fixing Both Near And Far Sight?
LASIK’s ability to fix both near and far sight depends on individual eye conditions. It may not fully correct presbyopia or complex refractive errors, and some patients might still need reading glasses or other vision aids after surgery.
Who Is a Good Candidate for Lasik to Fix Both Near And Far Sight?
Good candidates are those with stable eye prescriptions and specific refractive errors that LASIK can safely treat. An eye specialist will evaluate if monovision LASIK or other treatments are appropriate to address both near and far sight effectively.
The Final Word – Can Lasik Fix Both Near And Far Sight?
LASIK offers powerful correction for nearsightedness or farsightedness individually but fixing both perfectly in one go remains complex due to anatomical limits. Monovision techniques allow many patients over 40 to manage distance and near vision without glasses effectively—but adaptation varies greatly among individuals.
For younger patients without presbyopia seeking freedom from glasses for either near or far sight alone—LASIK remains a top choice delivering excellent results quickly. Those needing full-range focus might consider alternatives like PresbyLASIK or lens replacement procedures after thorough discussion with their surgeon.
In essence: Yes, LASIK can fix both near and far sight under specific circumstances—especially using monovision—but it’s not a universal cure-all. Success hinges on tailored treatment planning aligned with your unique eyes and lifestyle demands. Consulting a qualified ophthalmologist will clarify what’s achievable for your vision goals today.
