摘要
相干光断层扫描(optical coherence tomography,OCT)是一项非接触性、非侵入性、高分辨率的生物组织结构显像技术,可提供形态学图像和量化分析。其在角膜屈光手术方面的应用除了角膜厚度的测量、角膜瓣的评估、负压对视网膜影响的评估等方面之外,在圆锥角膜的筛查、角膜病变的观察与手术设计、术前黄斑区病变的筛查和术后视力预测等方面也发挥重要的作用。重视OCT在角膜屈光手术中的综合应用,有利于提高角膜屈光手术的效果。
Optical coherence tomography （OCT）, a non-contact, non-invasive high resolution imaging of biological tissue structure technology, can provide morphological image and quantitative analysis. Application of OCT on the corneal refractive surgery is not confined to the corneal thickness measurements, corneal flap assessment and evaluation of the effect of negative pressure on the retina. OCT can also play an important role in keratoconus screening, corneal disease observation and operation design, preoperative screening of the pathological changes in the macular area and postoperative prediction of vision. OCT optimal application is important for the im- provement of efficacy in corneal refractive surgery.
