To describe the role of microscope integrated optical tomography (Mi-OCT) in removal of intrastromal corneal foreign body.
A young male presented with trauma to the right eye with sugarcane stick. Ocular examination revealed two sugarcane particles, approximately 3.5 mm in greatest dimension, embedded in the corneal stroma. For removal of foreign body, Mi-OCT was switched on and the area of interest was focused. Sugarcane particles appeared as hyperreflective structures embedded in the corneal stroma with everted edges of the overlying corneal epithelium and anterior stroma.
Both the sugarcane particles were removed successfully under real time images provided by Mi-OCT without causing any inadvertent damage to the corneal stroma.
Mi-OCT can be used as an adjunct in emergency surgical procedures like removal of intrastromal corneal foreign bodies with accurate precision.
描述显微镜集成光学断层扫描（Mi - OCT）在角膜基质内异物取出术中的作用。
一名年轻男性右眼被甘蔗杆击伤。眼部检查发现角膜基质内嵌入两颗甘蔗颗粒，最大尺寸约为3.5毫米。为取出异物，开启Mi - OCT并聚焦感兴趣区域。甘蔗颗粒表现为嵌入角膜基质的高反射结构，上方角膜上皮和前基质边缘外翻。
在Mi - OCT提供的实时图像引导下，两颗甘蔗颗粒均成功取出，未对角膜基质造成任何意外损伤。
Mi - OCT可作为一种辅助手段用于诸如角膜基质内异物取出等急诊手术，具有精确的准确性。
