Laser Eye Surgery (LASIK/PRK): Pre‑Existing Conditions That Increase Risk

Certain medical conditions and factors can increase complications or make laser refractive surgery inadvisable. A thorough preoperative evaluation by an experienced ophthalmologist is essential.

Conditions That May Contraindicate or Increase Risk

1. Uncontrolled Diabetes: Impaired wound healing, higher infection risk.
2. Autoimmune Disorders: Lupus, rheumatoid arthritis – increased inflammation, poor healing.
3. Corneal Conditions: Keratoconus, corneal scars, thin corneas – structural instability.
4. Severe Dry Eye Syndrome: Compromises postoperative healing and visual quality.
5. Glaucoma: Surgery can affect intraocular pressure monitoring and management.
6. Cataracts: Cataract surgery should precede refractive surgery.
7. Retinal Conditions: Retinal detachment, macular degeneration – increased risk of complications.
8. Pregnancy or Breastfeeding: Hormonal changes alter corneal shape and healing.
9. Active Infections or Systemic Illness: Wait until fully recovered.
10. Certain Medications: Isotretinoin (Accutane), antihistamines, blood thinners – may affect healing or increase bleeding.

Next Steps

Disclose your full medical history and medications during your consultation. The surgeon will assess corneal topography, thickness, pupil size, tear film, and overall ocular health to determine candidacy.
