1a shows a hyperreflective structure (yellow arrow head) embedded in the anterior cornea, suggestive of an intracorneal sugarcane particle. The proximal end of the particle can be seen piercing through the corneal epithelium and anterior stroma causing a lamellar laceration. 1b shows that the sugarcane particle was held using Lim's forceps (red arrow) while looking at the real-time images provided by Mi-OCT. 1c shows the tract of the sugarcane particle which appeared as a hyporeflective space (orange arrowhead) in the anterior cornea. 1d shows the second sugarcane particle which appeared as a hyperreflective structure (yellow arrowhead), with a narrow tract (yellow arrow). ILM forceps (blue arrow) was guided using the real-time images to retrieve it atraumatically. 1e shows the sugarcane particle lying on the corneal surface after removal. It appeared hyperreflective with back shadowing. 1f shows lamellar tissue defect (red arrowhead) once both foreign bodies were removed.

Sugarcane particles appeared as hyperreflective structures embedded in the corneal stroma with everted edges of the overlying corneal epithelium and anterior stroma (Figure 1a (Fig. 1)). The first FB was removed using Lim's forceps under real-time Mi-OCT image guidance (Figure 1b (Fig. 1)), thus preventing inadvertent damage to the surrounding corneal tissue. Once the FB was removed, its tract could be clearly appreciated on the Mi-OCT as a hyporeflective lucency in the anterior cornea (Figure 1c (Fig. 1)). Subsequently the second organic FB was imaged with Mi-OCT and a decision to remove it with 25 gauge internal limiting membrane (ILM) forceps was made since the tract through which it entered was very narrow (Figure 1d (Fig. 1)). The lamellar epithelial and anterior stromal tissue defect (Figure 1f (Fig. 1)) was irrigated with 0.5% preservative-free moxifloxacin and balanced salt solution, and a 14 mm bandage contact lens was placed.
