Easy and Accurate Operation
Obtaining accurate interpupillary measurements with the PDM is easy. Operators simply align the measuring lines to the Purkinje images on the patient's corneas. Measurement data can be obtained for a single eye, or both eyes, and results are accurate to within 0.5 mm. Interpupillary distance for a range of focusing points can be obtained by selecting the appropriate focus distance on the circular dial. The PDM's LCD displays measurement data in a clear, easy-to-read format.
Long Battery Life
The PDM automatically switches off after one minute of inactivity to ensure long battery life. In addition, the patient fixation target is illuminated by a low-power LED, further extending battery life and ensuring virtually maintenance-free operation.
