Is My Vision Too Good for LASIK? Exploring the Possibilities

As someone who has always had perfect vision, I’ve often wondered if my eyesight is too good for Lasik. Like many people, I’m intrigued by the promise of better vision without glasses or contacts, but I’m also hesitant to mess with something that’s working just fine. After all, Lasik is a surgical procedure and it involves permanently altering the shape of your cornea – that’s not something to take lightly.

However, as I’ve researched Lasik over the years, I’ve come to learn that there are many factors that determine whether or not you’re a good candidate for the procedure – and having perfect vision isn’t necessarily one of them. In fact, some people with mild prescription glasses can be turned away from Lasik due to other factors, such as issues with the thickness of their cornea or the shape of their eye.

So, is my vision too good for Lasik? The answer is that it’s not that simple. While the overall health of your eyes is an important factor, there are a number of other factors to consider as well. So if you’re thinking about Lasik, it’s important to do your research and talk to a qualified ophthalmologist to determine if it’s the right choice for your unique situation.

What factors determine eligibility for LASIK surgery?

Not everyone is a good candidate for LASIK surgery. A thorough eye exam is necessary to determine your eligibility for the procedure. Here are some of the factors that are taken into consideration:

  • Age: A person must be at least 18 years old before they can undergo LASIK surgery.
  • Stable vision: Your vision prescription must have been stable for at least one year before the surgery.
  • Overall eye health: You should not have any underlying eye diseases or conditions that could affect the success of the surgery.
  • Eye anatomy: The shape and thickness of your cornea will be evaluated to determine if LASIK is a safe option for you.
  • Eye injury or infection history: If you have a history of eye injuries or infections, you may not be eligible for LASIK surgery.
  • Other medical conditions: Certain medical conditions such as autoimmune diseases may make LASIK a risky procedure.

Additionally, your lifestyle and occupation may affect your eligibility for LASIK. For example, if you engage in contact sports or work in an occupation where there is a high risk of eye injury, LASIK may not be recommended.

Can someone with perfect vision get LASIK?

It’s a common misconception that only those with poor vision are eligible for LASIK surgery. However, individuals with perfect or near-perfect vision may also benefit from LASIK. Here’s what you need to know:

  • Although LASIK is primarily used to correct refractive errors such as nearsightedness, farsightedness, and astigmatism, it can also enhance visual acuity in those with already good vision.
  • For example, individuals who have 20/20 vision may still experience blurry vision or other visual aberrations, such as halos around lights, glare, or difficulty reading in low light settings.
  • LASIK can address these issues by reshaping the cornea to create a clearer, sharper image on the retina, ultimately improving visual acuity and reducing the need for glasses or contacts.

However, it’s important to note that not everyone is a good candidate for LASIK, regardless of their visual acuity. Other factors, such as age, overall eye health, and corneal thickness, may impact a person’s suitability for the procedure. Prior to undergoing LASIK, it’s important to consult with an experienced eye surgeon to ensure that the procedure is safe, appropriate, and likely to achieve the desired results.


So, can someone with perfect vision get LASIK? The answer is yes! If you experience visual aberrations or other issues, LASIK surgery can help achieve a clear, crisp vision that may not have been previously attainable. However, as with any medical procedure, it’s important to explore your options, consult with a qualified surgeon, and make an informed decision about your eye health and vision care.

Ultimately, LASIK surgery is a powerful tool that can transform the way we see the world, but it’s important to approach it with caution and respect for the complex nature of our eyes and vision. Whether you’re considering LASIK for the first time or are simply curious about what it can do for your vision, take the time to learn more about the procedure, its benefits and limitations, and how it may be able to help improve your quality of life.

The role of corneal thickness in LASIK eligibility

One of the most important factors to consider before having LASIK eye surgery is corneal thickness. A thin cornea can make it difficult to perform the procedure safely and effectively, so doctors must evaluate each patient’s corneal thickness before determining their eligibility for the surgery.

Factors that affect corneal thickness

  • Age
  • Gender
  • Genetics
  • Eye disorders
  • Injuries or surgeries on the eye

Corneal thickness requirements for LASIK

The cornea is the outermost part of the eye and the first structure that light passes through before entering the inner eye. During LASIK, a thin flap is created in the cornea, and a laser is used to reshape the corneal tissue in order to correct refractive errors.

In order to be eligible for LASIK, a patient’s corneal thickness must be at least 500 microns. Anything less than that can increase the risk of complications during the surgery and may not provide enough tissue to create a flap that will heal properly.

Corneal Thickness LASIK Eligibility
Less than 500 microns Not a candidate for LASIK
Between 500-550 microns Evaluation required
More than 550 microns Candidate for LASIK

Patients with corneas between 500-550 microns may still be eligible for LASIK, but their doctor will need to perform additional tests to evaluate their cornea’s stability and determine if the procedure can be safely performed.

Can LASIK cause overcorrection in patients with exceptional vision?

Lasik is infamous for providing patients with an improved vision by correcting the refractive errors such as nearsightedness, farsightedness, or astigmatism. However, it is a common question that comes to mind- “Can LASIK cause overcorrection in patients with exceptional vision?”

  • It is improbable for Lasik to overcorrect the patient’s vision, especially those who have exceptional vision.
  • The Lasik procedure aims to improve the vision of patients by precisely reshaping the cornea.
  • The chances of overcorrection depend on the surgeon’s experience, skill set, and the type of refractive error the patient has.

Keep in mind that Lasik is an adequate surgical procedure to improve the vision. It is essential to consult your surgeon and discuss your options to understand the procedure’s detailed process.

Additionally, Lasik technology is continually evolving, so it is best to choose a reputable Lasik center with cutting-edge technology to get precise results.

Factors that a surgeon considers to prevent overcorrection

Lasik is an efficient procedure to correct the patient’s refractive errors. However, it is essential to follow its strict guidelines to prevent any complications or overcorrection. Here are some of the factors that the surgeon considers to avoid overcorrection:

  • The thickness of the patient’s cornea
  • The pupil size of the patient
  • The type of refractive error
  • The patient’s age
  • The patient’s overall health, prescription medications, and medical history

The surgeon performs a detailed analysis of every patient to ensure the best results. The chances of overcorrection depend on the patient’s eye anatomy and the surgeon’s skill set.

Side effects of overcorrection

Overcorrection after Lasik is rare, but if it occurs, patients may experience side effects such as:

Possible Side effects of Overcorrection Description
Blurred Vision If the patient is overcorrected, it can cause blurry vision, making it difficult to perform everyday tasks, such as reading or driving.
Halos and starbursts The light that enters the patient’s eye spreads and causes halos and starbursts, making it difficult to focus in low light conditions.
Dry eye Patients with overcorrection may experience dry eyes, making it itchy, burning, or red.

It is essential to follow the post-operative recovery instructions and regularly attend follow-up appointments to ensure a risk-free and successful Lasik procedure.

In conclusion, overcorrection after Lasik is uncommon, especially in patients with exceptional vision. Unlike traditional glasses/contacts, Lasik allows patients to experience clear vision without any hassle. Remember to discuss and consider all your options before getting the Lasik procedure and choose a reputable center with expertise.

How is astigmatism taken into consideration during LASIK screening?

During a LASIK screening, the surgeon evaluates several factors to determine if a patient is a good candidate for the procedure. One of these factors is astigmatism, which is a condition that causes blurred vision due to the irregular shape of the cornea.

  • Astigmatism can be measured using a device called a keratometer, which measures the curvature of the cornea at various points.
  • In some cases, additional tests may be needed to evaluate the severity of the astigmatism and determine if it can be corrected with LASIK.
  • The surgeon will also take into consideration the patient’s overall eye health, visual acuity, and prescription strength before making a final determination.

If a patient has significant astigmatism, it may not be possible to fully correct it with LASIK alone. In these cases, other vision correction procedures such as PRK or implantable lenses may be recommended.

It’s important for patients to communicate any pre-existing conditions or concerns with their surgeon during the initial consultation, as this can help ensure the best possible outcome for their vision correction procedure.

Astigmatism Severity Likelihood for LASIK Correction
Mild (less than 1.00 diopter) High
Moderate (1.00-2.00 diopters) Moderate
Severe (more than 2.00 diopters) Lower

In summary, astigmatism is an important factor that is taken into consideration during LASIK screening. While mild to moderate astigmatism can typically be corrected with LASIK, more severe cases may require alternative vision correction procedures. By communicating openly with their surgeon and undergoing a thorough evaluation, patients can ensure the best possible outcome for their vision correction procedure.

The Importance of Stable Vision for LASIK candidacy

When considering LASIK surgery, it is crucial to have stable vision. Stable vision means that your eyeglass or contact lens prescription has not changed in at least a year. This is important for a few reasons:

  • Having stable vision ensures that any vision correction done during LASIK will be accurate and effective. If your prescription is still changing, the surgery may not fully correct your vision, or it may need to be repeated in the future.
  • LASIK surgery can cause dry eyes as a side effect. If you already have unstable vision and this side effect develops, it can make it more difficult to achieve stable vision in the future.
  • Pregnancy, certain medications, and medical conditions can cause changes in vision. Having stable vision before undergoing LASIK can help ensure that any changes are not related to these factors and are a true indication of your prescription.

Factors That Can Affect Stable Vision

There are a number of factors that can affect how stable your vision is:

  • Age: The eyes’ ability to focus changes with age, so stable vision may be more difficult to achieve in older patients.
  • Pregnancy: Hormonal changes during pregnancy can cause changes in vision.
  • Medical conditions: Certain eye conditions, such as keratoconus, can cause unstable vision.
  • Medications: Some medications can cause changes in vision.
  • Eye injuries: Trauma to the eye can cause changes in vision that may not stabilize immediately.

Tests for Stable Vision

Your ophthalmologist will perform a number of tests to determine if your vision is stable enough for LASIK surgery:

  • Eye exam: This exam will look for any changes in vision and assess the overall health of your eyes.
  • Corneal topography: This test measures the shape of your cornea, which is important for determining the success of LASIK surgery.
  • Pachymetry: This test measures the thickness of the cornea. A certain level of corneal thickness is necessary for successful LASIK surgery.


Having stable vision is essential for successful LASIK surgery. If you are considering LASIK, talk to your ophthalmologist about whether your vision is stable enough for the procedure.

Pros Cons
Accurate and effective vision correction Dry eye may make future vision instability more likely
Ensuring prescription changes are not caused by medications or medical conditions Age and certain medical conditions may make stable vision more difficult to achieve
Trauma to the eye can cause temporary vision instability

LASIK risks and complications for patients with exceptionally good eyesight.

While LASIK is generally a successful and safe procedure for those with nearsightedness, farsightedness, and astigmatism, there are still some risks and complications associated with the surgery. These risks are generally higher for patients with exceptionally good eyesight.

  • Overcorrection: If your vision is already close to 20/20, there’s a risk that the surgery will overcorrect and leave you with vision that’s better than 20/20. While this might sound like a good thing, it can cause discomfort and other vision problems.
  • Undercorrection: Similarly, there’s a risk that the surgery won’t fully correct your vision, leaving you with less than perfect sight.
  • Dry eyes: LASIK involves cutting a flap in the cornea, which can damage the nerves that stimulate tear production. This can lead to dry eyes, which can be discomforting and cause vision problems.

However, it’s important to note that these risks aren’t common and that most patients with good eyesight have successful LASIK surgeries. The key to minimizing your risk is to choose an experienced surgeon and have a thorough consultation before the procedure to determine if LASIK is the right choice for you.

Another potential complication of LASIK for patients with good eyesight is the development of small aberrations in the cornea. While these aberrations may be small and almost unnoticeable, they can still cause reduced contrast sensitivity or halos around lights at night.

Complication Risk for patients with good eyesight
Overcorrection Higher risk
Undercorrection Higher risk
Dry eyes Higher risk
Corneal aberrations Slightly higher risk

It’s important to discuss any potential risks and complications with your surgeon and to have realistic expectations for the outcomes of LASIK surgery, especially if you already have good eyesight. While LASIK can be a life-changing procedure, it’s important to weigh the risks and benefits before deciding if it’s right for you.

Recommended pre-operative tests for LASIK patients with exceptional vision.

Although LASIK is a safe and effective procedure, it is not without potential complications. Therefore, it is essential to undergo certain pre-operative tests to ensure that you are a good candidate for the surgery. These pre-operative tests evaluate your eye health, including your vision, the shape and thickness of your cornea, and the overall health of your eyes.

  • Corneal Topography: This test measures the exact curvature of your cornea, which is crucial for determining the right treatment plan.
  • Pachymetry: This test measures the thickness of your cornea to ensure there is enough tissue to safely perform the LASIK surgery.
  • Wavefront Analysis: This test maps the overall quality of your visual function, including any higher-order aberrations, which can affect your vision in low light conditions.

However, patients with exceptional vision may require additional testing to ensure that they maintain their excellent eyesight after the surgery. Here are some additional pre-operative tests that LASIK patients with exceptional vision may undergo:

1. Dilated Eye Exam: This exam allows your doctor to examine the inner structures of your eye, including your retina, which can be essential for people with exceptional vision who may have underlying eye conditions that could affect their Lasik surgery.

2. Contrast Sensitivity Test: Contrast sensitivity is the ability to distinguish between different shades of gray. This test ensures that you can see well in different lighting conditions, including low light conditions, which are particularly important for people with exceptional vision who may expect nothing less than perfect vision.

3. Visual Field Testing: Visual field testing maps your peripheral vision, which is essential for people with exceptional vision, who may be using their side vision frequently for certain activities or sports. This test ensures that there is no loss of peripheral vision after the surgery.

Test Purpose
Corneal Topography Measure the exact curvature of your cornea.
Pachymetry Measure the thickness of your cornea.
Wavefront Analysis Map the overall quality of your visual function
Dilated Eye Exam To examine the inner structures of your eye.
Contrast Sensitivity Test Ensure that you can see well in different lighting conditions.
Visual Field Testing Map your peripheral vision.

By undergoing these additional pre-operative tests, LASIK patients with exceptional vision can ensure that they will maintain their excellent eyesight post-surgery. It is crucial to undergo these tests to ensure that the LASIK procedure will enhance the quality of your vision and provide you with the desired results that meet your high expectations.

Post-operative care for LASIK patients with superior visual acuity.

After undergoing LASIK surgery, patients with superior visual acuity require post-operative care to guarantee the effectiveness of the procedure and the longevity of the result. The following are some essential guidelines that every patient must follow:

  • Attend post-operative follow-up appointments with your surgeon
  • Avoid rubbing your eyes for at least a month
  • Wear protective eyewear such as sunglasses outdoors to avoid harmful UV rays

Adhering to these guidelines will help prevent complications such as infection or regression of vision. In addition to these fundamental care requirements, LASIK patients with superior visual acuity must take additional precautions to protect their exceptional vision.

Patients should avoid exposing their eyes to dust, smoke, and dry air, often often found in windy environments. Those who work in dusty or hazardous environments should wear protective goggles to reduce the risk of eye injury. It is also essential to avoid using any eye drops, including artificial tears, without consulting with your surgeon first.

Additionally, patients with superior visual acuity should expect to experience temporary halos, glare, and eye dryness after the procedure. These symptoms are common and typically subside within a few weeks, but be sure to discuss any concerns with your surgeon. In some cases, eye drops or medications may be recommended to alleviate these symptoms.

Post-operative tip Description
Avoid strenuous activities Avoid any high-intensity physical activity for at least a week after surgery, including running, swimming, and contact sports
Avoid applying makeup near the eyes Avoid applying any eye creams, mascaras, or eyeliners within two weeks after surgery
Follow eye drop medication instructions Use eye drops as instructed by your surgeon to keep your eyes lubricated and help prevent infection

Remember to follow all post-operative care guidelines provided by your surgeon to maintain your superior vision and enjoy a lifetime of visual freedom.
