Figure 1-Corneal Waveform
Pachymeters traditionally have been devices that provide the thickness of the human cornea in the form of a number that is displayed to the user. Micro Medical Devices' PalmScan P2000 is the first pachymeter in the market to push the envelope by providing users the additional ability to display, store and recall of corneal waveforms on a per patient basis.
Corneal waveforms are the visual representation of the ultrasonic echoes through the corneal stroma. Figure 1 depicts the corneal waveform of a human eye. The figure consists of two main peaks. The first is form the transducer-cornea interface, while the second peak is from the posterior corneal interface.
By adding the ability to capture, store and recall corneal waveforms and place cursors to manually measure distances, Micro Medical Devices has made measurable advances in the science of pachymetry. One of these advances is the ability to compare corneal waveforms of patients by superimposing them.
