The difference of mean intraocular pressure among readings obtained with the lens in place, after lens removal and lens reinsertion were not statistically significant in bandage contact lens group and in low myopic contact lens group. But the high myopic contact lens group showed statistically significant difference of mean intraocular pressure obtained with the lens in place, after lens removal and lens reinsertion. In addition, the intraocular pressure readings measured immediately after myopic contact lens reinsertion revealed poor reliability.关键词 Tono-Pen , Soft contact lenses

我们把受测者分为三组：低度近视组，高度近视组和配戴治疗性隐形眼镜组，每组分别以受测者未戴隐形眼镜时的眼压做基准，而以其他三种情形的眼压分别与之比较，结果发现以Tono-Pen测量低度近视组和配戴治疗性隐形眼镜组的眼压值可信度较高，但是戴上隐形眼镜之后马上测量的眼压值较不准确，而高度近视组的测量值则出现变异的现象，可信度较低。

We placed the lens holder, testing lens, and the assistant lens in the testing optical path. When the testing lens was mounted in the lens holder, we took five dynamic interferograms. After rotating the testing lens by 180 degrees along the edge of the testing lens, we took another set of interferograms. Then, we could evaluate the centering error of the testing optical element by analysing these two sets of interferograms.

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.
