Twenty eyes in group A received the conventional approach by using toothed forceps through corneal limbus incision, and 22 eyes in group B underwent the novel method through the opposite corneal limbus incision. RESULTS:The success rate of ACFB once removal was 75%(15/20) in group A, and 100%(22/22) in group B. The average operation time of group A was significantly longer compared with group B(34.9±9.88 min vs 22.13±8.85min; P〈0.05). The average size of corneal limbus incision in group A was significantly larger than that of group B(4.85±1.89 mm vs 3.95±1.17 mm; P〈0.05). The corneal limbus incision suturing were conducted in all eyes in group A, and only 5 eyes in group B. CONCLUSION:Removal of ACFB using a prism contact lens and 23-gauge foreign body forceps is a safer, more effective, and convenient technique compared with the conventional approach.展开更多
