Depth and width of corneal wounds post corneal foreign body removal
Reviewed by Su Young

This was a prospective study of 63 eyes of 63 patients undergoing corneal foreign body (FB) removal with a 27G needle at the slit-lamp; 96.8% of the patients were men with mean age 35.8 ±11.0 years. Regarding location of FBs, 26 (41.3%) were in the central region, 21 (33.3%) were in the paracentral region, and 16 (25.4%) were in peripheral cornea. The mean depth and width of the corneal wounds were 117.0 ±42.5µm and 332.9 ±99.4µm, respectively. The mean percentage of corneal wound depth was 18.9 ±6.1%. From follow-up based on 20 patients, the width of the wound increased and the thinnest stromal thickness at the wound site decreased over the two months. In conclusion, based on AS-OCT findings in this study corneal FBs generally affected the anterior central and paracentral cornea with less than approximately 0.2mm depth and 0.5mm width.
