To introduce a novel approach in removal of anterior chamber angle foreign body (ACFB) using a prism contact lens and 23-gauge foreign body forceps.
Data of 42 eyes of 42 patients who had undergone removal of ACFB using a prism contact lens and 23-gauge foreign body forceps from January 2008 to October 2013 were collected and analyzed. 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.
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±9.88min 22.13±8.85min; <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 3.95±1.17 mm; <0.05). The corneal limbus incision suturing were conducted in all eyes in group A, and only 5 eyes in group B.
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.
介绍一种使用棱镜接触镜和23G异物镊取出前房角异物（ACFB）的新方法。
收集并分析2008年1月至2013年10月间42例患者42只眼使用棱镜接触镜和23G异物镊取出ACFB的资料。A组20只眼采用传统方法，通过角膜缘切口用齿镊取出；B组22只眼采用新方法，通过对侧角膜缘切口取出。
A组ACFB一次取出成功率为75%（15/20），B组为100%（22/22）。A组平均手术时间显著长于B组（34.9±9.88分钟对22.13±8.85分钟；P<0.05）。A组角膜缘切口平均大小显著大于B组（4.85±1.89毫米对3.95±1.17毫米；P<0.05）。A组所有眼均进行了角膜缘切口缝合，B组仅5只眼进行了缝合。
与传统方法相比，使用棱镜接触镜和23G异物镊取出ACFB是一种更安全、有效且便捷的技术。
