摘　　要：术中相干光断层扫描(intraoperative optical coherence tomography,iOCT)能实时显示手术中的眼部结构,提供手术过程和器械与组织相互作用的动态视图,从而增强对手术过程的了解,促进手术关键步骤的决策,以获得最佳手术效果。目前,通过手持或集成于显微镜,iOCT正越来越多地用于各种眼前段手术中的辅助决策,特别是在白内障超声乳化手术、角膜移植、青光眼手术和配合不佳的小儿眼病患者的检查、诊断方面具有重要意义。另外,iOCT在屈光手术和眼表疾病中的作用也越来越得到重视。目前的iOCT系统的局限性与仪器的兼容性、术野的自动跟踪以及实时图像的自动化分析有关。Intraoperative optical coherence tomography(iOCT)enables real-time visualization of ocular structures during surgery and provides a dynamic view of the surgical process and instrument-tissue interactions to enhance our understanding of the surgical process,facilitate decision making at crucial steps of surgery,and optimize outcomes.At present,the applications of iOCT in anterior segment are continually expanding,whether hand-held or microscope integrated,and increasingly emerging as a useful adjunct in phacoemulsification,keratoplasty,glaucoma surgeries.It assumes both diagnostic and therapeutic importance in pediatric cases where pre-operative assessment is often not feasible.Otherwise,the applications of iOCT in refractive surgeries and ocular surface disorders is increasingly being evaluated.The limitations of present-day iOCT systems are related to instrument compatibility,automated tracking of the surgical field,and on-table volumetric analysis of the real-time images.
