顶焦度计又称对光机、查片机，可用来测量球光镜镜度、散光镜镜度、棱镜镜度以及散光轴线和光学中心点等，是眼镜片冷加工中必不可少的检测仪器。
The lensometers is also called measural lens dioptre instrument, to measure spherical lens dioptre, cylindric lens dioptre and axis, prism dioptre, and lens optical center etc.
目的：证实采用接触镜专用标准透镜组标定的焦度计不能准确测定被测角膜接触镜的顶焦度。
Objective:To confirm that the lensometer adjusted by the special lenses group for contact lenses can't express the back vertex power of contact lenses.
