A pocket-sized self-illuminated diagnostic instrument is described which projects a series of white dots upon the cornea from the center to the periphery radially disposed in a fashion similar to an astigmatic dial. The battery-operated instrument allows for a rapid qualitative estimate of corneal astigmatism and the meridians involved.
本文描述了一种袖珍式自发光诊断仪器，该仪器从中心到周边以类似于散光视标的方式在角膜上投射出一系列径向排列的白点。这种由电池供电的仪器能够快速对角膜散光及相关子午线进行定性评估。
