Microscope integrated OCT (Mi-OCT) guided retrieval of intrastromal corneal foreign body

INTRODUCTION: To describe the role of microscope integrated optical tomography (Mi-OCT) in removal of intrastromal corneal foreign body. METHODOLOGY: 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. RESULTS: Both the sugarcane particles were removed successfully under real time images provided by Mi-OCT without causing any inadvertent damage to the corneal stroma. CONCLUSION: Mi-OCT can be used as an adjunct in emergency surgical procedures like removal of intrastromal corneal foreign bodies with accurate precision.
