I designed a small diameter magnet tip for intraocular removal of foreign bodies, particularly at the time of vitrectomy. Advantages of the intraocular tip include: (1) reduced likelihood of scraping of the foreign body along the retinal surface while in the magnetic field; (2) reduced chance of incarcerating the retina or choroid, or both, between the magnet and the foreign body during removal. Although the intraocular tip is less strong than conventional shorter tips, it provides greater control in the removal of intraocular foreign bodies when sufficient magnet strength is present.
我设计了一种小直径的磁头，用于眼内异物取出，特别是在玻璃体切割术时。眼内磁头的优点包括：（1）在磁场中时，异物沿视网膜表面刮擦的可能性降低；（2）在取出过程中，视网膜或脉络膜或两者被夹在磁体和异物之间的机会减少。尽管眼内磁头比传统的短磁头强度小，但当有足够的磁体强度时，它在眼内异物取出中能提供更好的控制。
