眼内异物的X 线定位方法很多,如巴尔金氏法,斯维特氏法,角膜缝环法等。其中以缝环法定位准确可靠,但该法需缝环、拆环,给病人造成痛苦。我们采用软角膜接触镜和细毫针制成的金属环做成软角膜镜定位器做×线定位。在1990年至1992年,我们用这种方法做眼内异物定位共70例,效果满意。现介绍如下。材料:选质地较厚的软角膜接触镜一只和细长的针刺针一根。制法:把细毫针紧绕在一直径11mm 或12mm的棍(如钢笔杆)上一周,用止血钳固定,然后把弯 X-ray positioning intraocular foreign body many ways, such as Barkin method, Svet’s method, corneal suture method. Among them, the accurate and reliable positioning by sewing method, but the law need to suture, remove the ring, causing pain to the patient. We use soft corneal contact lens and fine needle made of metal ring made of soft corneal mirror positioner to do × line positioning. In 1990 to 1992, we use this method to do a total of 70 cases of intraocular foreign body localization, with satisfactory results. Now introduced as follows. Material: thick texture of a soft contact lens and a slender needle acupuncture needles. System of law: the thin needle tightly around a diameter of 11mm or 12mm stick (such as the pen holder) on the week, with hemostatic clamp, and then bend
