摘　　要：目的评价自制角膜微型磨钻与传统注射针头在角膜铁屑异物取出术中的效果。设计回顾性比较性病例系列。研究对象铁屑异物侵入角膜基质层内的Ⅱ度角膜铁屑异物患者3475例3621眼,采用随机数字表法将患者分为甲、乙两组,甲组1730例1758眼,乙组1745例1863眼。方法甲组采用传统注射针头剔除角膜异物,乙组采用自制角膜微型磨钻清除角膜异物。主要指标手术时间、需二次手术率、角膜锈环清除时间、角膜愈合时间、术后并发症。结果甲、乙两组手术时间分别为(3.2±0.7)分、(1.1±0.2)分,需二次手术率分别为50.11%、0.81%,角膜锈环清除时间分别为(3.6±0.6)天、(1.1±0.3)天,角膜愈合时间分别为(6.8±1.1)天、(3.3±0.8)天,术后并发症发生率分别为7.0%、1.23%。两组以上各指标比较差异均有统计学意义(P均<0.05)。结论自制角膜微型磨钻较传统注射针头在角膜铁屑异物处理方面有较大的优势,在临床使用中安全有效。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.
