Before undergoing LASIK eye surgery, all candidates must undergo a thorough medical screening to ensure the procedure is safe and effective. A key part of this evaluation is reviewing your complete medication history, as certain prescription drugs can significantly impact surgical outcomes. These medications can interfere with the body's natural healing process, cause severe dry eye syndrome, or lead to refractive instability, all of which are contraindications for LASIK.
Medications Affecting the Body's Healing Process
Any medication that compromises the immune system or hinders the body's ability to heal poses a significant risk for LASIK surgery. The procedure involves creating a thin flap in the cornea, which must heal properly to ensure a stable and clear outcome.
- Isotretinoin (Accutane, Amnesteem, Claravis): This powerful oral acne medication is a significant contraindication for LASIK. Isotretinoin works by reducing the output of oil glands, which can lead to severe and chronic dry eye. The resulting dry eye can increase the risk of corneal scarring, improper healing, and infection after LASIK. Most surgeons require patients to be off isotretinoin for a significant period, often 6 to 12 months, before considering the surgery.
- Systemic Steroids (e.g., Prednisone): Oral corticosteroids can suppress the immune response, delay wound healing, and increase the risk of infection. Patients on high-dose or long-term steroid therapy are typically not candidates for LASIK. The decision depends on the dosage and the underlying condition being treated.
- Immunosuppressants: Medications used to suppress the immune system in patients with autoimmune disorders (like lupus or rheumatoid arthritis) or organ transplants prevent proper healing and increase the risk of post-operative complications. These patients often have compromised healing mechanisms and are generally ineligible for LASIK.
Medications Causing Severe or Chronic Dry Eye
LASIK can temporarily exacerbate dry eye symptoms as a normal part of the healing process. For individuals already prone to dry eyes due to medication, this effect can be amplified, leading to poor healing, discomfort, and poor visual outcomes.
- Antihistamines and Decongestants: Over-the-counter and prescription allergy medications are known to cause dry eyes. While often a temporary concern, your surgeon may recommend discontinuing use in the weeks leading up to and following surgery to ensure the eyes are in optimal condition for healing.
- Certain Antidepressants: Some antidepressants can cause dry eye as a side effect. Your surgeon will evaluate your specific medication and its impact on your tear film to determine if it will affect your LASIK recovery.
- Hormonal Medications: Oral contraceptives and other hormonal therapies, particularly those containing estrogen, can affect tear production and corneal thickness. These effects may be temporary and a surgeon will assess stability before proceeding.
Medications Causing Refractive Instability
Refractive stability—having a stable vision prescription for at least a year—is a fundamental requirement for LASIK. Certain medications can cause fluctuations in vision, making it impossible for the surgeon to accurately determine the correct laser treatment.
- Amiodarone: This antiarrhythmic drug can cause corneal deposits, which can affect the accuracy of the laser treatment. Patients on this medication are generally disqualified from LASIK.
- Other Medications: Less common drugs like colchicine, sumatriptan, and levonorgestrel implants can also cause ocular side effects that influence LASIK eligibility.
Underlying Conditions and Their Medications
It's important to remember that it is often the underlying medical condition, for which the patient is taking medication, that is the primary reason for disqualification. For example, a patient with lupus is typically on immunosuppressants, and both the disease and the medication can impair healing and increase risk.
Comparison of Medications and LASIK Impact
| Medication Type | Common Examples | Primary Impact on LASIK | Waiting Period Before Surgery |
|---|---|---|---|
| Oral Acne Medication | Isotretinoin (Accutane) | Causes severe and chronic dry eye, impairs healing | 6–12 months off medication |
| Systemic Steroids | Prednisone | Suppresses immune system, delays wound healing | Dosage and condition-dependent; often contraindicated |
| Immunosuppressants | Azathioprine, Methotrexate | Inhibits healing, increases infection risk | Contraindicated; risk outweighs benefits |
| Antihistamines/Decongestants | Loratadine (Claritin), Pseudoephedrine | Causes dry eye, affects tear film quality | May require temporary discontinuation before surgery |
| Hormonal Medications | Oral Contraceptives | Can cause refractive instability, affect tear film | Surgeon assesses stability; may require temporary pause |
| Antiarrhythmics | Amiodarone (Cordarone) | Causes corneal deposits that affect laser accuracy | Generally considered a contraindication |
What to Do If Your Medication Disqualifies You
Being ineligible for LASIK due to medication does not mean you have no options for vision correction. Your ophthalmologist can discuss safe alternatives that may be suitable for your specific situation. These alternatives may include:
- PRK (Photorefractive Keratectomy): This procedure reshapes the cornea's surface without creating a flap. While PRK has a longer recovery time, it may be an option for some patients, although many of the same medical contraindications still apply.
- ICL (Implantable Collamer Lens): For patients ineligible for laser eye surgery, phakic intraocular lenses can be implanted to correct vision. This procedure does not require corneal reshaping.
- Refined Glasses or Contact Lenses: Non-surgical correction remains a safe and effective option for many. In cases where medication causes refractive instability, managing your vision with glasses or contacts is often the most appropriate course of action.
Conclusion: The Importance of a Thorough Medical History
Because a patient's overall health and medication regimen directly affect healing and outcomes, open communication with your ophthalmologist is vital for determining LASIK eligibility. Hiding or forgetting to mention a medication, whether prescription or over-the-counter, can lead to serious complications, including delayed healing, corneal problems, and infection. While a drug might not permanently disqualify you, it may require a significant waiting period or a different treatment approach. A qualified eye surgeon will assess your full medical history and help you find the safest path to clear vision, whether through LASIK or an alternative.
