Objective: To evaluate the effect of corneal micro drill for removing cornea iron foreign body.Design: A retrospective comparative case series.Participants: 3475 cases 3621 eyes with deep corneal iron foreign body were randomly divided into two groups, group A with 1730 cases 1758 eyes and group B with 1745 cases 1863 eyes.Methods: For group A, traditional hypodermic needle was used to remove corneal foreign body, while in group B, self made corneal micro grinding drill was used.Main Outcome Measures: Operation time, requiring second operation rate, corneal rust ring clearance time, corneal wound healing time, postoperative complications.Results: The operation time and needing second operation rate in group A and B was 3.2 ± 0.7 min and 1.1 ± 0.2 min, 50.11% and 0.81% respectively. Corneal rust ring clearance was 3.6 ± 0.6 d and 1.1 ± 0.3 d in group A and B respectively. Corneal wound healing time was 6.8 ± 1.1 d and 3.3 ± 0.8 d. Postoperative complication rate was 7.0% and 1.23%. The difference was significant (all P < 0.05).Conclusions: Corneal micro drill has a greater advantage than the traditional injection needle in the cornea iron foreign body treatment.
