[摘要]
成像技术的进步彻底改变了眼科领域，改变了我们对眼科疾病的理解、诊断和治疗。扫频源光学相干断层扫描(SS-OCT)是一种最新的非接触式高分辨率成像技术。它进一步提高了成像深度和扫描速度，增加了新的算法和功能。SS-OCT允许对角膜结构进行三维评估，提供角膜前、后表面的曲率和高度图以及角膜厚度图。这可以帮助眼科医生筛查和诊断角膜病变，如圆锥角膜、角膜营养不良和变性。SS-OCT更快、更精准和更灵敏的角膜测量有助于对即将进行角膜和屈光手术的患者做好术前计划和术后监测。文章总结SS-OCT技术的发展及其在角膜疾病中潜在的临床效用与在手术中的应用进展，以支持更多未来可能的研究和临床治疗。

[Abstract]
Advances in imaging technology have revolutionized the field of ophthalmology, changing the understanding, diagnosis, and treatment of ophthalmic diseases. Swept-source optical coherence tomography(SS-OCT)is a non-contact high-resolution imaging technology. It further improves imaging depth and scanning speed, adds new algorithms and features. The application of SS-OCT enables the three-dimensional evaluation of corneal structures, offering curvature and height maps for both the anterior and posterior surfaces of the cornea, as well as precise corneal thickness mapping. These invaluable tools aid ophthalmologists in effectively screening and diagnosing various corneal lesions such as keratoconus, corneal dystrophy, and degeneration. Moreover, the enhanced speed, accuracy, and sensitivity provided by SS-OCT measurements facilitate improved surgical planning and postoperative monitoring for patients undergoing refractive surgery or keratoplasty. This article reviews the development of SS-OCT technology and its potential clinical utility in corneal diseases and surgical application, in order to support more possible future research and clinical treatment.
