Accurately assessing and dealing with anterior segment changes in the eyes of patients with lens diseases can better guide the operation details during surgery and make reasonable plans for possible intraoperative and postoperative complications. Applying the intraoperative optical coherence tomography technique, this study analyzes the correlation between preoperative, intraoperative anterior segment structural changes and postoperative surgical effects in patients with lens diseases, and evaluates the clinical benefits of intraoperative optical coherence tomography technique in lens surgery. This study is intended to further improve the diagnosis and treatment quality of clinical lens diseases.
In the eyes of patients with lens diseases, there are often some special anterior segment changes, including ectopia lentis, abnormal lens morphology, and rupture of the lens capsule. These changes can be caused by ocular trauma, congenital anomalies, or be secondary to other ocular diseases and systemic diseases. Accurately assessing and dealing with these anterior segment changes can better guide the operation details during surgery and make reasonable plans for possible intraoperative and postoperative complications. This study is based on intraoperative optical coherence tomography technique, analyzes the correlation between preoperative, intraoperative anterior segment structural changes and postoperative surgical effects in patients with lens diseases, and evaluates the clinical benefits of intraoperative optical coherence tomography technique in lens surgery. This study is intended to further improve the diagnosis and treatment quality of clinical lens diseases.
