a control panel operated by the examiner, for driving the drive mechanism or measurement section by manual operation; and a control means that measures the eye axis length by controlling the measurement section and controls drive of the drive mechanism in accordance with the control signal that is...
A dual-axis chart is a graph that lets you plot data sets with different types or scales of measurement against two separate axes. One axis is typically on the left, and one is on the right. This setup allows you to compare different yet related information in a single, coherent visual,...
The point source of light approaches the eye. As it approaches, the point source increases in size. When the light source becomes sufficiently large, the fixation target becomes visible. Upon touching of the instrument to the eye, ultrasound measurement of the dimension of the eye preferably ...
