Odyssey Evaluation in Post LASIK Patients
Recruiting now · Phase 4
Conditions studied: Cataract
In brief
This prospective study evaluates the visual and refractive outcomes of the TECNIS Odyssey intraocular lens (IOL) implanted in patients with a history of myopic LASIK. Given the unique optical challenges of post-LASIK eyes, including altered corneal curvature and higher-order aberrations, the study aims to assess the IOL's performance in terms of distance, intermediate, and near vision, and patient satisfaction. Its design features may offer favorable outcomes in these patients.
