Who is Ineligible for Laser Eye Surgery?


Reasons to Avoid Laser Eye Surgery

Laser eye surgery, also referred to as LASIK (Laser-Assisted In Situ Keratomileusis), is a widely sought-after procedure for correcting vision issues like nearsightedness, farsightedness, and astigmatism. Although LASIK is generally safe and effective, it is not suitable for everyone. This article explores the reasons why certain individuals should avoid laser eye surgery and provides a comprehensive understanding of the procedure.

Understanding LASIK

LASIK is a surgical technique that utilizes a laser to reshape the cornea, the transparent front portion of the eye, in order to correct refractive errors. By modifying the cornea's shape, LASIK aims to enhance vision and reduce dependence on glasses or contact lenses. Before considering the procedure, it is crucial to comprehend the potential risks and limitations associated with LASIK.

Common Eligibility Requirements

Several eligibility requirements must be met before undergoing laser eye surgery. The following factors are typically taken into consideration:

  1. Medical Conditions and Considerations

  2. Certain medical conditions can impact the outcome of laser eye surgery. Individuals with the following conditions are often advised against LASIK:
  • Pregnancy and Breastfeeding: Pregnant or breastfeeding women are usually recommended to postpone LASIK until after breastfeeding. Hormonal changes during pregnancy and breastfeeding can temporarily alter corneal shape and affect visual stability. Consulting with an ophthalmologist is essential to determine the optimal timing for LASIK.
  • Age Restrictions: LASIK is typically not performed on individuals under 18 years of age or those whose vision is still changing. Vision stability is a crucial factor in determining the procedure's success. Alternative vision correction methods may be more suitable for younger individuals.

  • Eye Diseases and Disorders: Certain eye diseases and disorders may disqualify individuals from LASIK. Conditions such as cataracts, glaucoma, keratoconus, and severe dry eye syndrome can impact the safety and effectiveness of the surgery. A thorough evaluation by an ophthalmologist is necessary to identify any underlying eye conditions.
  • Chronic Illnesses: LASIK may not be advisable for individuals with certain chronic illnesses due to potential risks and complications associated with these conditions. Diseases such as diabetes, autoimmune disorders, and immunodeficiency disorders can affect the healing process. It is crucial to discuss these factors with a qualified eye surgeon.
  • Medications and Treatments: Certain medications and treatments can interfere with the healing process after LASIK and increase the risk of complications. Individuals taking corticosteroids, immunosuppressants, or medications affecting blood clotting may not be suitable candidates for the surgery. Ophthalmologists consider an individual's current and past medications and treatments.
  1. Unrealistic Expectations

Having realistic expectations about the outcomes of LASIK is crucial. While LASIK can significantly improve vision, it may not guarantee perfect vision or completely eliminate the need for visual aids. Unrealistic expectations can lead to disappointment. Therefore, individuals considering LASIK should have a clear understanding of the potential benefits and limitations of the procedure.




  1. Corneal Thickness

Corneal thickness plays a significant role in determining LASIK eligibility. Individuals with thin corneas may not have enough tissue for the laser to safely reshape, potentially increasing the risk of complications. Ophthalmologists assess corneal thickness through various tests to determine suitability for LASIK.

  1. Dry Eye Syndrome

Individuals with severe or chronic dry eye syndrome may not be suitable candidates for LASIK. Dry eye syndrome can cause discomfort, blurred vision, and slower healing after the surgery. Effective management of the dry eye condition is necessary before considering LASIK.

  1. Unstable Vision

LASIK is most effective when performed on individuals with stable
