Who Should Not Have Laser Eye Surgery: Exploring Eligibility and Considerations


Laser eye surgery has become very popular in order to fix common vision problems like nearsightedness, farsightedness, and astigmatism. It is a procedure that can help people see better and rely less on glasses or contacts. However, not everyone is a good person for this surgery. It is important to know if you’re eligible and understand the possible risks involved. Laser eye surgery, like LASIK or PRK, uses lasers to reshape the cornea of the eye and fix vision issues. It’s a modern and advanced technique that aims to improve how the eye focuses and make vision clearer.

But before getting too excited about laser eye surgery, it is important to know that it is not suitable for everyone. Some people may have factors that make them unsuitable candidates for the procedure. By understanding who might not be a good fit, we can better understand the limitations of laser eyes surgery. Let’s take a closer look at the factors to consider when determining if someone is eligible for this surgery.

Understanding Laser Eye Surgery:

Laser eye surgery includes different procedures like LASIK and PRK that can fix vision problems. Let’s learn more about them:

LASIK (Laser-Assisted in Situ Keratomileusis):

LASIK is the most common laser eyes surgery. It involves creating a thin flap on the eye’s surface, using a laser to reshape the cornea underneath, and then putting the flap back in place. It is a quick and comfortable procedure.

PRK (Photorefractive Keratectomy):

PRK is another type of laser eyes surgery suitable for people with thinner corneas. In PRK, the surgeon removes the outer layer of the cornea, reshapes the underlying tissue with a laser, and allows it to heal naturally over time.

Laser eyes surgery corrects refractive errors, which affect how the eye’s focuses light. Here’s a simple explanation:

Nearsightedness (Myopia):

If you have trouble seeing distant objects, laser eyes surgery for myopia flattens the cornea, helping you see faraway things more clearly.

Farsightedness (Hyperopia):

If you struggle with close-up vision, laser eyes surgery for hyperopia makes the cornea steeper, improving your ability to see things up close.


For blurry or distorted vision caused by astigmatism, laser eye surgery reshapes the cornea to make it more symmetrical and fix the problem.


Several benefits of Laser eye surgery

  1. Improved Vision: It can greatly improve your vision, reducing the need for glasses or contacts. Many people experience clearer and sharper eyesight after the surgery.
  2. Convenience and Freedom: Laser eyes surgery reduces your reliance on glasses or contacts, making everyday activities, sports, and hobbies more convenient.
  3. Quick Recovery: Most people recover fast and can resume their normal activities within a few days after the surgery.


  1. Dry Eyes: Some people may experience temporary or long-lasting dryness in their eyes after surgery, which can be uncomfortable and require additional care.
  2. Night Vision Issues: A small number of patients may have trouble with night vision, such as seeing glare or halos around lights, especially in dim lighting.
  3. Under correction or Overcorrection: In some cases, the desire level of vision correction may not be fully achieve, resulting in remaining vision problems or overcorrection, where objects may appear closer than they actually are.
  4. Risk of Infection or Complications: Though rare, there is a small risk of infection or other complications with any surgical procedure. Following post-operative instructions and choosing an experienced surgeon helps minimize these risks.

Eligibility Criteria for Laser Eye Surgery:

To determine if someone is a good candidate for laser eye surgery, certain factors are considered. Let’s look at the important criteria:

Age Restrictions and Stability of Vision:

Laser eye surgery is typically suitable for adults aged 18 and above for LASIK, and 21 and above for PRK. Your vision should also be stable for about a year or two, meaning your glasses or contact lens prescription hasn’t changed much.

Evaluating the Severity of Refractive Errors:

The degree of your vision problem, like nearsightedness, farsightedness, or astigmatism, is taken into account. Laser eye surgery can correct a certain range of these issues, but extreme cases might require alternative treatments.

Overall Eye Health and Medical Conditions:

Good eye health is essential for successful surgery. You should have healthy corneas, enough tear production, and no underlying eye conditions or diseases that could affect healing. Conditions like glaucoma, cataracts, severe dry eyes, or corneal diseases may make you ineligible. Some medical conditions like autoimmune diseases, diabetes, or immunodeficiency disorders may also impact healing and increase risks. It’s important to discuss any existing medical conditions with your eye care professional to evaluate suitability for the surgery.

Pregnancy and Breastfeeding Considerations:

Hormonal changes during pregnancy and breastfeeding can affect vision stability. It’s generally recommended to wait several months after breastfeeding before considering laser eyes surgery. During pregnancy, it’s best to postpone the procedure as the effects on the baby are unknown. Laser eye surgery’s safety during pregnancy hasn’t been extensively studied. To ensure the well-being of both the mother and baby, it’s advisable to wait until after pregnancy and breastfeeding to undergo the surgery.

Following these criteria helps determine if laser eye surgery is a good option for you. It’s important to remember that specific circumstances may influence the criteria, and a thorough evaluation and consultation with an experienced eye surgeon are crucial in determining your eligibility.

Identifying Those Who Should Not Have Laser Eye Surgery:

While laser eye surgery can be a great option for many people, there are situations where it may not be suitable. Let’s see who might not be good candidates for the procedure:

Patients with Unstable Vision or Prescription Changes:

Laser eye surgery works best when your vision has been stable for a while. If your vision keeps changing or your glasses or contacts prescription keeps getting updated, it’s better to wait until your vision settles down before considering the surgery.

Individuals with Chronic Medical Conditions Affecting Eye Health:

Some ongoing medical conditions can affect your eye health and how well you heal after the surgery. Conditions like diabetes, autoimmune diseases, or problems with your immune system can impact the success of laser eye surgery. It’s important to discuss your medical history with an eye doctor to see if the surgery is safe for you.

Specific Eye Conditions that May Disqualify Candidates:

Certain eye conditions make laser eyes surgery unsuitable. These conditions include:

  1. Keratoconus: It causes thinning and bulging of the cornea, leading to distorted vision.
  2. Corneal Scarring: Scarring on the cornea can affect the surgery’s results.
  3. Cataracts: Laser eye surgery isn’t recommended if you have significant cataracts. Instead, cataract surgery may be a better choice.
  4. Glaucoma: If you have glaucoma and it’s affecting your optic nerve, laser eye surgery might not be safe for you.

Patients with Unrealistic Expectations or High-Risk Professions:

It’s important to have realistic expectations for laser eyes surgery. If you expect perfect vision without glasses or have unrealistic hopes about the outcome, it’s essential to reconsider. Also, if you work in high-risk professions like professional sports or the military, where eye injuries or extreme conditions are common, laser eyes surgery may not be recommended due to the higher risk of complications.

Identifying who should not have laser eyes surgery helps ensure safety and success. It’s vital to have a detailed discussion with an eyes doctor who can assess your specific situation, medical history, and eyes health to determine if laser eyes surgery is the right choice for you.

Potential Risks and Complications:

It’s important to know about the potential risks and complications that can occur with laser eye surgery. Here’s a simple explanation:

1. Dry Eyes:

After the surgery, your eyes may feel dry and uncomfortable. You might experience a gritty feeling or blurry vision. Usually, these symptoms improve over time, but in rare cases, they may persist or need further treatment.

2. Night Vision Issues:

Some people may have trouble seeing at night after the surgery. They may see glare, halos around lights, or have difficulty seeing clearly in low-light conditions. These problems often get better with time, but it’s good to be aware of them.

3. Under correction or Overcorrection:

While the goal of the surgery is to improve your vision, there’s a small chance that you may not achieve the exact level of correction needed. This can mean that you still need to use glasses or contacts, or you may have objects appearing closer than they actually are. Regular check-ups with your eye doctor can help address these concerns.

4. Corneal Flap Complications:

In LASIK surgery, a thin flap is created on the cornea. There’s a slight risk of complications related to this flap. These can include the flap moving out of place, irregularities in the flap, or cells growing under the flap. Although these complications are rare, they may require additional treatment or, in rare cases, further surgery.

5. Infection and Other Complications:

Like any surgery, there’s a small risk of infection or other complications. Following the instructions provided by your surgeon after the surgery can help minimize these risks. Factors like slow healing, thinning of the cornea, or scarring can also contribute to complications.

Importance of Informed Consent and Thorough Pre-Operative Assessment:

Before the surgery, your eye doctor will have a detailed discussion with you about the potential risks, complications, and limitations of the procedure. This is called informed consent. They want to make sure you fully understand the benefits and possible drawbacks so that you can make an informed decision. A thorough pre-operative assessment is also crucial. It involves examining your overall eye health, checking the shape and thickness of your cornea, evaluating your vision, and discussing your medical history. This helps identify any potential issues and ensures the best possible results.

Managing Expectations and Understanding Limitations:

It is important to have realistic expectations about the surgery. While it can greatly improve your vision, it might not give you perfect vision, and you may still need glasses or contacts for some activities or as you get older. Every person is different, so it’s important to have open and honest communication with your eye doctor. They can give you a clear idea of what to expect based on your specific situation and answer any questions you have. By being well-informed, having realistic expectations, and following the advice of your eyes doctor, you can make a confident decision about laser eyes surgery and minimize the potential risks and complications.

Alternative Vision Correction Options:

If laser eye surgery isn’t the right choice for you, don’t worry! There are other ways to correct your vision. Let’s look at some simple and advanced options:

  1. Glasses and Contact Lenses: Glasses and contact lenses are common and easy ways to improve your vision. Glasses are like a pair of customized lenses that you wear on your face, while contact lenses sit directly on your eyes. They come in different styles and prescriptions to suit your needs. Your eye doctor can help you find the right fit and prescription for clear vision.
  2. Implantable Lenses: For people with more serious vision problems or who can’t have laser eye surgery, implantable lenses can be an option. These special lenses are surgically placed inside your eye, alongside your natural lens. They can correct your vision and give you clear sight. Implantable lenses are usually recommended for those with very high nearsightedness or thin corneas.
  3. Corneal Implants: Corneal implants are small, clear devices that are put into your cornea (the front part of your eye) to reshape it and improve your vision. They’re often used for people with a condition called keratoconus, which makes the cornea bulge out. The implants help flatten the cornea and make your vision clearer.
  4. Personalized Consultations and Professional Advice: The best way to decide on an alternative vision correction option is to talk to an eye doctor. They can give you personalized advice based on your specific needs and eye health. They’ll consider things like your prescription, the shape of your eyes, and your lifestyle to recommend the best option for you. It’s important to work with a professional who can guide you through the decision-making process.

Final Thoughts on “Who Should Not Have Laser Eye Surgery”

laser eye surgery is a popular procedure for vision correction, but it may not be suitable for everyone. It’s important to understand the eligibility criteria and potential risks of eyes surgery. Certain individuals, such as those with unstable vision, chronic medical conditions affecting eye health, specific eye conditions, or unrealistic expectations, may not be good candidates for laser eye surgery. However, there are alternative options available for vision correction. These include glasses, contact lenses, implantable lenses, and corneal implants. Each option has its own benefits and considerations, and it’s crucial to have personalized consultations and professional advice from an eye care specialist to determine the best choice for your specific needs.

Before making a decision, it’s important to thoroughly understand the potential risks and complications associated with laser eye surgery. Informed consent and a comprehensive pre-operative assessment are essential to ensure the best possible outcomes. Managing expectations and understanding the limitations of the surgery will contribute to a more satisfying experience.

By considering alternative vision correction options and seeking professional advice, you can find the right solution to improve your vision and enhance your quality of life. Remember to consult with an eye care professional who can guide you through the decision-making process and help you make an informed choice about the best path for your vision correction journey.
