We evaluated a miniaturized digital and electronic tonometer, the Tono-Pen, for accuracy of intraocular pressure measurement in the presence of a contact lens. In the manometric study, the Tono-Pen was used to measure a known intraocular pressure, ranging from 10 mm Hg to 60 mm Hg in a cadaver eye over soft contact lenses with different powers and a plano-T bandage lens. There was significant bias in pressure measurement over all contact lenses except for the plano-T, which had no bias at any level. In the clinical study, the intraocular pressures of 40 eyes in 20 normal patients were measured with and without a plano-T contact lens in place. Analysis of variance showed no significant interactive effect between the right and left eyes, with or without the lens. There was no significant difference in the Tono-Pen measurement of intraocular pressure over a plano-T contact lens compared with no lens.
我们评估了一种小型数字式电子眼压计——托诺笔（Tono-Pen），以确定在佩戴隐形眼镜的情况下测量眼压的准确性。在压力测量研究中，使用托诺笔在一具尸体眼上，通过不同屈光度的软性隐形眼镜和平光T型绷带镜，测量已知眼压，范围为10毫米汞柱至60毫米汞柱。除平光T型镜片在任何眼压水平均无偏差外，在所有隐形眼镜上进行眼压测量时均存在显著偏差。在临床研究中，对20名正常患者的40只眼睛在佩戴和平光T型隐形眼镜的情况下测量眼压。方差分析显示，无论有无镜片，左右眼之间均无显著交互作用。与不戴镜片相比，托诺笔在平光T型隐形眼镜上测量眼压时无显著差异。
