我们每年都收治一些角膜被栗子壳上的刺扎伤的病例.木刺折断,深深刺入角膜基质深层,有时尖端进入前房,断端不暴露在角膜表面.由于木刺吸收水分膨胀紧紧嵌在角膜组织中,取出很困难.对这样的异物用常规的方法有时半小时也取不出.近2年我们采用角膜铲针取异物就很容易.方法是:用地卡因麻醉后,在裂隙灯下,用消毒的角膜铲针从异物周围的角膜组织刺入到木质异物上,很容易就把异物挑出.对其它角膜深层异物,可以把角膜铲针刺入到异物后面把异物挑出.
Every year, we treat some cases of puncture wounds on the shell of the chestnut shell, which break down and deeply pierce the deep corneal stroma, sometimes the tip enters the anterior chamber and the broken ends are not exposed on the corneal surface. Tightly embedded in the corneal tissue, remove very difficult for such foreign body with the conventional method sometimes half an hour can not get the past two years we use corneal shovel needle foreign body is very easy.Method: anesthesia with cocaine, Under the slit lamp, with a disinfected corneal shovel needle from the corneal tissue around the foreign body piercing wooden foreign body, it is easy to pick foreign body .Other corneal deep foreign body, you can put the corneal shovel needle behind the foreign body foreign body Singled out.
