Dry eye treatment may expand refractive surgery eligibility. A new study found that treating dry eye disease significantly improved corneal biomechanical parameters, potentially making more patients eligible for laser vision correction. Patients with mild or subclinical dry eye who previously had abnormal corneal screening results may benefit from treatment before being reconsidered for surgery.
Good news for patients who've been told they can't get LASIK: treating dry eye disease first might change that. A retrospective study published in the Journal of Refractive Surgery found that a structured dry eye treatment protocol significantly improved key corneal biomechanical measurements — the same ones used to screen patients for laser vision correction.
The study analyzed 50 eyes from 34 patients who had initially shown abnormal tomographic biomechanical index (TBI) scores — a red flag in refractive surgery screening. After completing dry eye treatment (which included preservative-free drops, omega-3 supplements, cyclosporine, and collagen punctal plugs), patients showed meaningful improvements across multiple biomechanical parameters, and their TBI scores dropped significantly.
Key Takeaways:
Why it matters: Many patients are turned away from refractive surgery due to abnormal corneal screening results that may actually be driven by dry eye disease. This study suggests that treating the underlying condition first could safely expand the pool of eligible candidates — a meaningful shift in how pre-surgical screening is approached.
