Laser eye surgery offers incredible benefits for vision correction, enhancing quality of life for busy professionals and those with active lifestyles. However, not everyone is an ideal candidate. Certain medical conditions and eye health factors can make laser procedures risky or less effective. Understanding these limitations is essential for making safe, informed decisions about vision correction.
1. Unstable Vision or Changing Prescriptions
Patients whose prescription is still changing are not suitable for laser eye surgery.
Practical impact: Surgery may not correct vision accurately, leading to under- or over-correction.
Who it affects most: Young adults, people whose eyesight is rapidly changing, or those with progressive myopia.
2. Severe Dry Eyes
Chronic dry eye syndrome can complicate healing and worsen discomfort after surgery.
Practical impact: Increased irritation, slower recovery, and suboptimal visual outcomes.
Who it affects most: Office workers exposed to prolonged screen time or individuals in dry climates.
3. Corneal Irregularities or Thin Corneas
A thin or irregular cornea may not withstand reshaping during laser surgery.
Practical impact: Increased risk of complications, such as ectasia or unstable vision.
Who it affects most: Patients with keratoconus or naturally thin corneas.
4. Autoimmune Disorders
Conditions like lupus or rheumatoid arthritis can affect healing.
Practical impact: Slower recovery and higher risk of infection or complications.
Who it affects most: Individuals with systemic autoimmune conditions or immune-related eye issues.
5. Diabetes with Uncontrolled Blood Sugar
Uncontrolled diabetes can impair corneal healing and increase infection risk.
Practical impact: Higher likelihood of complications and delayed recovery.
Who it affects most: Diabetic patients not maintaining stable blood sugar levels.
6. Pregnancy or Nursing
Hormonal fluctuations during pregnancy or breastfeeding can temporarily change vision.
Practical impact: Inaccurate correction and unpredictable results.
Who it affects most: Expecting or nursing mothers considering laser eye surgery.
7. Severe Glaucoma or Retinal Issues
Patients with advanced glaucoma or retinal diseases may face additional risks.
Practical impact: Increased susceptibility to eye pressure changes or post-surgery complications.
Who it affects most: Individuals with glaucoma, retinal detachment, or diabetic retinopathy.
8. Chronic Eye Infections
Active eye infections or recurring conjunctivitis can prevent safe surgery.
Practical impact: Infection may worsen or interfere with proper healing.
Who it affects most: Individuals with frequent bacterial or viral eye infections.
9. Age-Related Vision Changes
Patients with advanced presbyopia may not achieve full distance and near correction from LASIK alone.
Practical impact: Additional corrective measures may be needed post-surgery.
Who it affects most: People over 45 seeking comprehensive vision correction.
10. History of Eye Surgery or Trauma
Previous eye surgeries or significant trauma can complicate corneal reshaping.
Practical impact: Reduced effectiveness of surgery and higher risk of complications.
Who it affects most: Patients with cataract surgery, corneal transplants, or ocular injuries.

FAQs About Laser Eye Surgery Eligibility
Q1: Can I undergo laser eye surgery if I have mild diabetes?
Laser eye surgery is generally safe for patients with well-controlled diabetes. Uncontrolled blood sugar can impair healing, so an assessment of overall eye health and glycemic control is essential before surgery.
Q2: Is age a limiting factor for LASIK?
Most adults over 18 with stable vision are suitable. However, patients over 45 may need additional correction for near vision due to presbyopia, which LASIK may not fully address.
Q3: Can people with autoimmune disorders have LASIK?
Patients with autoimmune disorders are often at higher risk for complications and slower healing. Each case requires careful evaluation and may need specialised approaches or alternative procedures.
Q4: What if I have thin corneas?
Thin or irregular corneas may make traditional LASIK unsafe. Alternatives like PRK or implantable lenses may be recommended, depending on corneal measurements and eye health.
Q5: Are there temporary conditions that affect eligibility?
Yes, pregnancy, nursing, or recent eye infections can temporarily disqualify patients. Surgery can be reconsidered once conditions stabilise to ensure optimal outcomes.
