Laser eye surgery has transformed the way we approach vision correction, offering a potential solution for many individuals seeking to reduce their reliance on glasses or contact lenses. While these procedures, such as LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy), have been successful for countless patients, they are not suitable for everyone. Various factors influence eligibility for laser eye surgery, including age, eye health, underlying medical conditions, and lifestyle. This article explores who should not undergo laser eye surgery and why, ensuring prospective patients can make informed decisions about their vision correction options.
Laser Eye Surgery
What is Laser Eye Surgery?
Laser eye surgery involves using laser technology to reshape the cornea—the clear front surface of the eye—to correct refractive errors. The primary types of laser eye surgery include:
LASIK: Involves creating a thin flap in the cornea and using a laser to reshape the underlying tissue. The flap is then repositioned.
PRK: The outer layer of the cornea is removed before reshaping the corneal tissue directly with a laser. This method is typically recommended for patients with thinner corneas.
SMILE: A newer procedure that involves creating a small incision in the cornea to remove a lenticule of tissue, reshaping the cornea without creating a flap.
Common Refractive Errors Treated
Laser eye surgery is effective for several refractive errors, including:
Myopia (Nearsightedness): Difficulty seeing distant objects clearly.
Hyperopia (Farsightedness): Difficulty seeing nearby objects clearly.
Astigmatism: Blurred vision due to an irregularly shaped cornea.
Who Should Not Have Laser Eye Surgery?
While laser eye surgery can provide life-changing results for many, certain individuals may not be ideal candidates. Below are the primary categories of people who should avoid these procedures.
1. Individuals Under 18 Years of Age
Eye Development
The eyes are still developing in children and teenagers, and their vision can change significantly during these formative years. For this reason, most eye care professionals recommend that patients be at least 18 years old before considering laser eye surgery.
Stability of Vision: Even in those who are 18 or older, it is crucial that their vision has been stable for at least one year. If a patient’s prescription continues to change, they may not achieve the desired results from the surgery.
2. Individuals with Unstable Vision
Vision Fluctuations
Candidates with fluctuating vision—common in individuals with conditions like diabetes or those undergoing hormonal changes—are not ideal candidates. Unstable vision can lead to inaccurate measurements, potentially resulting in under- or over-correction.
Diabetic Retinopathy: Patients with diabetes should manage their condition and ensure stable blood sugar levels for several months before considering surgery, as fluctuations can adversely affect vision.
3. Patients with Severe Dry Eye Syndrome
Dry Eye Symptoms
Individuals suffering from severe dry eye syndrome should postpone laser eye surgery. The surgery can exacerbate dry eye symptoms, leading to discomfort and visual disturbances.
Evaluation: Prior to surgery, patients will undergo tests to assess tear production and eye surface health. Those diagnosed with moderate to severe dry eye may require treatments to manage symptoms before being considered for surgery.
4. People with Certain Eye Conditions
Underlying Eye Health Issues
Several eye conditions can disqualify a patient from undergoing laser eye surgery, including:
Keratoconus: A progressive condition where the cornea thins and bulges into a cone shape, causing visual distortion.
Glaucoma: An increase in intraocular pressure that can damage the optic nerve, potentially worsening after laser procedures.
Retinal Disorders: Conditions such as retinal detachment or severe diabetic retinopathy can increase the risk of complications post-surgery.
Comprehensive Eye Examination
A thorough eye examination is essential to identify any pre-existing conditions that may pose a risk during or after the procedure.
5. Individuals with Systemic Health Conditions
Overall Health Considerations
Several systemic health conditions can affect candidacy for laser eye surgery, including:
Autoimmune Disorders: Conditions like lupus or rheumatoid arthritis can impede healing after surgery.
Uncontrolled Diabetes: Patients with poorly controlled diabetes may face healing complications and fluctuations in vision.
Pregnancy and Breastfeeding: Hormonal changes during pregnancy can affect vision, making it advisable to wait until after childbirth and weaning before considering surgery.
6. Patients with Unrealistic Expectations
Psychological Considerations
Candidates should have realistic expectations regarding the outcomes of laser eye surgery. While many experience significant improvement in vision, perfection is not guaranteed.
Psychological Readiness: Prospective patients should undergo counseling to assess their mental preparedness for the procedure and its potential outcomes. Patients who have unrealistic expectations may experience dissatisfaction post-surgery.
7. Those with Specific Lifestyle Factors
Active Lifestyles and Occupations
Certain lifestyle factors and occupations may influence the decision to undergo laser eye surgery. For example:
Occupations with High Risk of Eye Injury: Individuals in occupations like construction, sports, or other physically demanding fields may be at greater risk for eye injuries post-surgery.
High Contact Sports: Athletes participating in high-contact sports should discuss the risks associated with having laser eye surgery, as the cornea may be more vulnerable to injury.
Post-Surgery Care Considerations
After laser eye surgery, patients must follow specific aftercare guidelines, including avoiding swimming, strenuous exercise, and activities that could lead to eye injuries for several weeks.
8. Individuals Taking Certain Medications
Medication Impacts
Some medications can affect healing or increase the risk of complications following laser eye surgery. Patients should disclose all medications to their eye care professional, including:
Blood Thinners: Medications that thin the blood can increase the risk of bleeding and complications during and after surgery.
Isotretinoin (Accutane): Commonly used for severe acne, this medication can lead to dry eyes, which may hinder recovery.
Certain Antidepressants: Some antidepressants may impact the body’s healing response.
Consultation with Healthcare Providers
Always consult healthcare providers regarding the safety of any medications taken before considering laser eye surgery.
Risks and Complications of Laser Eye Surgery
While laser eye surgery is generally safe, it does carry potential risks and complications, especially for those who may not be suitable candidates.
Common Risks
Under or Over-Correction: Some patients may not achieve the desired visual acuity, necessitating a second procedure.
Visual Disturbances: Issues such as glare, halos, or ghost images can occur, particularly at night.
Infection and Inflammation: Although rare, infections and inflammation can occur post-surgery, requiring medical intervention.
Long-Term Considerations
Changes in Vision: As individuals age, their vision may change due to factors like presbyopia, potentially necessitating reading glasses or other corrective measures even after surgery.

Conclusion
Laser eye surgery can be a life-changing option for many individuals seeking to improve their vision. However, not everyone is an ideal candidate for these procedures.
Age Considerations: Patients should generally be at least 18 years old, with stable vision before considering surgery.
Eye Health: Pre-existing eye conditions, such as keratoconus or glaucoma, may disqualify candidates.
Systemic Health Issues: Uncontrolled diabetes, autoimmune disorders, and certain medications can impact the safety and efficacy of laser eye surgery.
Lifestyle Factors: Individuals in high-risk occupations or with active lifestyles should weigh the risks of potential eye injuries post-surgery.
Realistic Expectations: Psychological readiness and realistic expectations regarding outcomes are critical for satisfaction after the procedure.
Before proceeding with laser eye surgery, individuals should consult with qualified eye care professionals who can evaluate their specific circumstances. A thorough discussion of the risks, benefits, and alternatives will help prospective patients make informed decisions about their vision correction options. Understanding who should not have laser eye surgery can lead to better outcomes and greater satisfaction with the final results.
