Who is studied
This study will enroll pediatric patients aged 0 to 16 years who were diagnosed with traumatic cataract and underwent cataract surgery at the Eye, Ear, Nose, and Throat Hospital of Fudan University, or the Eye Hospital of Wenzhou Medical University, or the First Affiliated Hospital of Nanjing Medical University. Eligible patients may have experienced either blunt or penetrating ocular trauma. Both unilateral and bilateral cases are included. All participants must be able to complete regular follow-up evaluations for at least 5 years after surgery. The study population reflects a broad spectrum of post-traumatic cataract severity and treatment modalities, representing real-world clinical settings.
